Image Recognition: What It Is and How It Works

We humans can easily distinguish between places, objects, and people based on images, but computers have traditionally had difficulties with understanding these images. Thanks to the new image recognition technology, we now have specific software and applications that can interpret visual information.

As always, let’s start with the basics. From time to time, you can hear terms like “Computer Vision” and or “Image Recognition”. These terms are synonymous, but there is a slight difference between the two terms. Let us explain.

Computer vision is a wide area in which deep learning is used to perform tasks such as image processing, image classification, object detection, object segmentation, image coloring, image reconstruction, and image synthesis. In computer vision, computers or machines are created to reach a high level of understanding from input digital images or video to automate tasks that the human visual system can perform.

Whereas, image recognition is a field of computer vision that interprets images to aid decision-making. Image recognition is the final stage of image processing, which is one of the most important tasks of computer vision. [1]

How does it work

Now, a few words about how image recognition works. Image recognition algorithms make image recognition possible. The first step here is gathering and organizing the data. Data organization means classifying each image and distinguishing its physical characteristics. Unlike humans, computers perceive a picture as a vector or raster image. So after the constructs depicting objects and features of the image are created, the computer analyzes them. Therefore, the correct collection and organization of data are essential for training the image recognition model, because if the quality of the data is discredited at this stage, it will not be able to recognize patterns at a later stage.

The second step of the image recognition process is building a predictive model. The classification algorithm has to be trained carefully, otherwise, it won’t be able to deliver its function. Image recognition algorithms use deep learning datasets to distinguish patterns in images. These datasets consist of hundreds of thousands of tagged images. The algorithm looks through these datasets and learns how the image of a particular object looks like. When everything is done and tested, you can enjoy the image recognition feature.

Image recognition vs. Image Processing

You should remember that image recognition and image processing are not synonyms. Image processing is a kind of computer vision. Image processing means converting an image into a digital form and performing certain operations on it. As a result, it is possible to extract some information from such an image.
Image processing stages

  • Color image processing — the colors are processed
  • Image enhancement — the quality of the image is improved and the hidden details are extracted
  • Image restoration — the image is cleaned from blurs and other unpleasant things
  • Representation and description — the processes data is visualized
  • Image acquisition — the image is captured and converted
  • Image compression and decompression — the size and resolution of the image are changed, if necessary
  • Morphological processing — the structure of the image’s objects is described
  • Image recognition — specific features of the image’s objects are identified

Image recognition: Visual Search

“The future of search will be about pictures rather than keywords.” Pinterest CEO, Ben Silbermann

Visual search uses real images (screenshots, web images, or photos) as an incentive to search the web. Current visual search technologies use artificial intelligence (AI) to understand the content and context of these images and return a list of related results. It is applied in more and more industries. One of them is e-commerce.

For instance, Boohoo, an online retailer, developed an app with the visual search feature. A user simply snaps an item they like, uploads the picture, and the technology does the rest. Thanks to image recognition, a user sees if Boohoo offers something similar and doesn’t waste loads of time searching for a specific item. Other applications of image recognition (already existing and potential) include creating city guides, powering self-driving cars, making augmented reality apps possible, teaching manufacturing machines to see defects, and so on. There is even an app that helps users to understand if an object of the image is a hotdog or not.

Visual Search Statistics

  • 90% of information transmitted to the human brain is visual.
  • 62% of millennials want visual search over any other new technology.
  • 45% of retailers in the UK now use visual search.
  • The global visual search market is estimated to exceed USD 14,727 million by 2023, an increase of + 9% over the forecast period 2018-2023. [4]

Visual Search Trends

  • Brands (in particular Mastercard) completely remove text from their images in favor of a designer expression of their identity.
  • Google search offers more and more visual possibilities with more images and an improved user interface. Google images increasingly follow Pinterest.
  • Pinterest combines visual search with text search, which should increase its reach.
  • Retailers are developing their visual search capabilities, rather than relying on search engines and social networks as intermediaries. [4].

Impact of AI on Image Recognition

We described how image recognition works, but you may still have a lot of questions regarding how to complete those stages. Here is an answer — do image recognition using AI. Artificial intelligence makes all the features of image recognition possible. To give you a better understanding, here are some of them:

Facial recognition

With the help of AI, a facial recognition system maps facial features from an image and then compares this information with a database to find a match. Facial recognition is used by mobile phone makers (as a way to unlock a smartphone), social networks (recognizing people on the picture you upload and tagging them), and so on. However, such systems raise a lot of privacy concerns, as sometimes the data can be collected without a user’s permission. Apart from this, even the most advanced systems can’t guarantee 100% accuracy. What if a facial recognition system confuses a random user with a criminal? That’s not the thing someone wants to happen, but this is still possible. However, technology is constantly evolving, so one day this problem may disappear.

Facial Recognition Trends in 2021

  1. Application of facial recognition models at airport

Face recognition is now being used at airports to check security and increase alertness. Due to increasing demand for high-resolution 3D facial recognition, thermal facial recognition technologies and image recognition models, this strategy is being applied at major airports around the world.

  1. Know who your customers are

In the finance and investment area, one of the most fundamental verification processes is to know who your customers are. As a result of the pandemic, banks were unable to carry out this operation on a large scale in their offices. As a result, face recognition models are growing in popularity as a practical method for recognizing clients in this industry.

  1. Robotic face recognition system

In 2020, India implemented an automatic facial recognition system, which will further improve the identity verification process for the National Crime Registration Bureau. It is expected that these systems will be very popular this year. [2]

Object recognition

Object recognition systems pick out and identify objects from the uploaded images (or videos). It is possible to use two methods of deep learning to recognize objects. One is to train the model from scratch, and the other is to use an already trained deep learning model. Based on these models, many helpful applications for object recognition are created. Visual search is probably the most popular application of this technology.

For example, the application Google Lens identifies the object in the image and gives the user information about this object and search results. As we said before, this technology is especially valuable in e-commerce stores and brands. [(3]).

Text detection

Everything is obvious here — text detection is about detecting text and extracting it from an image.

Pattern recognition

Pattern recognition means finding and extracting specific patterns in a given image. Those can be textures, facial expressions, etc.

Fingerprint scanning

Image analysis

Do you need a summary of a specific image? Then use AI for picture and image analysis. As a result, all the objects of the image (shapes, colors, and so on) will be analyzed, and you will get insightful information about the picture.

Use Cases of Image Recognition

Mobile e-commerce

An excellent example of image recognition is the CamFind API from image Searcher Inc. This technology provides an advanced level of mobile trading. CamFind recognizes items such as watches, shoes, bags, sunglasses, etc., and returns the user’s purchase options. Potential buyers can compare products in real-time without visiting websites. Developers can use this image recognition API to create their mobile commerce applications.

ViSenze is an artificial intelligence company that solves real-world search problems through deep learning and image recognition. ViSenze products are used by online buyers, online sellers, and media owners to use product recommendations and to direct advertisements. [5]

Gaming Industry

Recognition models and computer vision technologies have also had a great impact on the gaming industry. It is known that the Microsoft Kinect video game is listed in the Guinness Book of Records as the fastest-selling consumer electronics device. The game is based on computer vision and tracks the human body in real-time. [(5])

Healthcare

Detecting brain tumors or strokes and helping people with poor eyesight are some examples of the use of image recognition in the healthcare sector. The study shows that the image recognition algorithm detects lung cancer with an accuracy of 97%.

Moreover, Medopad, in cooperation with China’s Tencent, uses computer-based video applications to detect and diagnose Parkinson’s symptoms using photos of users. The Traceless motion capture and analysis system (MMCAS) determines the frequency and intensity of joint movements and offers an accurate real-time assessment.

With the increase in the ability to recognize computer vision, surgeons can use augmented reality in real operations. It can issue warnings, recommendations, and updates depending on what the algorithm sees in the operating system.

Banking

Banks are increasingly using facial recognition to confirm the identity of the customer, who uses internet banking. Banks also use facial recognition       ” limited access control ” to control the entry and access of certain people to certain areas of the facility.

For example, the Spanish Caixabank offers customers the ability to use facial recognition technology, rather than pin codes, to withdraw cash from ATMs.

Manufacturing

For pharmaceutical companies, it is important to count the number of tablets or capsules before placing them in containers. To solve this problem, Pharma packaging systems, based in England, has developed a solution that can be used on existing production lines and even operate as a stand-alone unit. A principal feature of this solution is the use of computer vision to check for broken or partly formed tablets.

Another example is a company called Sheltoncompany Shelton which has a surface inspection system called WebsSPECTOR, which recognizes defects and stores images and related metadata. When products reach the production line, defects are classified according to their type and assigned the appropriate class.

Image recognition and models play a huge role in the automotive sector. According to one report, by 2022, the total market for machine vision could reach up to $ 14.43 billion! [(6])

For example, Komatsu Ltd, a leading manufacturer of mining and construction equipment, recently announced plans to work with Nvidia to integrate the NVIDIA cloud technology package. The main reason for this was to extend site management services, security, and performance. It is also about implementing AI based on deep learning to track people and predict the movement of equipment to avoid dangerous interactions, thus increasing so increasing safety. [6]

Methods and Techniques for Image Processing with AI

Image processing is a method of converting an image into digital form and performing certain operations on it to obtain an improved image or extract useful information from it. This is a type of signal distribution in which the input is an image, such as a video frame or photo, and the output may have an image or features associated with that image.

Let’s start with the simplest things — methods of image processing. Currently, there are only two of them: analog and digital. The analog method is used for processing hard copies of images (like printouts). Above all, the mission of the digital one is to manipulate digital images using computer algorithms.

Regarding the techniques, they exist in spades, and we have already mentioned some of them. For instance, image restoration is considered both as a stage and technique of image processing. Here are some of the other techniques:

  • Pixelation — turning printed pictures into the digitized ones
  • Linear filtering — processing input signals and producing the output ones which are subject to the constraint of linearity
  • Edge detection — finding meaningful edges of the image’s objects
  • Anisotropic diffusion — reducing the image noise without removing crucial parts of the picture
  • Principal components analysis — extracting the features of the image

Tools for Image Recognition

Fortunately, you don’t have to develop everything from scratch — you can use already existing platforms and frameworks. Cloud Vision API from Google is one of the most popular of them. Features of this platform include image labeling, text detection, Google search, explicit content detection, and others. If you choose this option, you will be charged per image. However, the first 1000 images used each month are free.

The next variant is Amazon Rekognition (yes, we made no mistake, that’s Rekognition). It allows adding visual analysis features to your app, integrating face-based user verification, identifying diverse objects, detecting unsafe content, etc. You will be charged for using the platform, but you can still try it for free.

 

Finally, the last option to mention in our article — Azure Custom Vision Service. By using it, you can develop a new custom computer vision model and train it. Upload your own labeled images, tag them and improve your classifier — everything is very simple. Just like with Google and Amazon, where you pay only for what you use. A free trial is available as well.

Future of Image Recognition

Due to further research and technological improvements, computer vision will have a wider range of functions in the future.

Computer vision technologies will not only make learning easier but will also be able to distinguish more images than at present. In the future, it can be used in connection with other technologies to create more powerful applications.

Computer vision will play an important role in the development of general artificial intelligence (AGI) and artificial superintelligence (ASI), giving them the ability to process information as well or even better than the human visual system. In addition, by studying the vast number of available visual media, image recognition models will be able to predict the future.

Completing authorization with innovative glasses

Here are some of the most interesting ways that visual data can help us predict the future:

Ocean send erosion

NC State’s Coastal & Computational Hydraulics team developed a computer vision model called XBeach to analyze flooding and erosion during hurricanes. Computer vision helps researchers predict and reduce the future impact of severe storms on local communities and sand dunes.[7]

Deforestation

Using computer vision trained in satellite imagery and visual data from Earth, experts can remotely control those ecosystems that are threatened by deforestation. The technology helps identify and analyze emergencies and stop illegal actions before they cause unchangeable damage.[7]

Food production

Although modern agriculture still focuses mainly on growing a single crop on a large plot, computer vision software can help farmers manage a greater variety of crops more effectively by informing them what and when to plant. Machine learning can also learn from annotated images to more correctly predict yields and analyze the condition of plants and livestock.[7]
