AI Image Recognition: Common Methods and Real-World Applications

These insights can tell you a lot about consumers, like what brands they share or what content resonates with them. This affects how brands market to consumers, where marketers run campaigns, and even what products your business may want to create. These insights can even inform how you create ads and social media posts, since AI-powered image recognition can tell you which images and visuals produce the best results.

Let us start with a simple example and discretize a plus sign image into 7 by 7 pixels. Black pixels can be represented by 1 and white pixels by zero (Fig. 6.22). As the popularity and use case base for image recognition grows, we would like to tell you more about this technology, how AI image recognition works, and how it can be used in business. After the training, the model can be used to recognize unknown, new images.

The Process of Image Recognition System

In Figure (H) a 2×2 window scans through each of the filtered images and assigns the max value of that 2×2 window to a 1×1 box in a new image. As illustrated in the Figure, the maximum value in the first 2×2 window is a high score (represented by red), so the high score is assigned to the 1×1 box. The 2×2 box moves to the second window where there is a high score (red) and a low score (pink), so a high score is assigned to the 1×1 box.

Currently, online lessons are common, and in these circumstances, teachers can find it difficult to track students’ reactions through their webcams. Neural networks help identify students’ engagements in the process, recognizing their facial expressions or even body language. Such information is useful for teachers to understand when a student is bored, frustrated, or doesn’t understand, and they can enhance learning materials to prevent this in the future. Image recognition used for automated proctoring during exams, handwriting recognition of students’ work, digitization of learning materials, attendance monitoring, and campus security. So, let’s switch to the better and more modern way – machine learning image recognition. Each layer of nodes trains on the output (feature set) produced by the previous layer.

When computer vision works more like a brain, it sees more like people do

Solutions based on image recognition technology already solve different business tasks in healthcare, eCommerce and other industries. Image recognition (or image classification) is the task of identifying images and categorizing them in one of several predefined distinct classes. So, image recognition software and apps can define what’s depicted in a picture and distinguish one object from another. We have used TensorFlow for this task, a popular deep learning framework that is used across many fields such as NLP, computer vision, and so on. The TensorFlow library has a high-level API called Keras that makes working with neural networks easy and fun.

Essentially, you’re cleaning your data ready for the AI model to process it. On the other hand, in multi-label classification, images can have multiple labels, with some images containing all of the labels you are using at the same time. In single-label classification, each picture has only one label or annotation, as the name implies.
