At this point, computer vision is the hottest research field within deep learning. It fits in many academic subjects such as Computer science, Mathematics, Engineering, Biology, and psychology. Computer vision represents a relative understanding of visual environments. Therefore, due to its cross-domain mastery, many scientists believe the field paves the way towards Artificial General Intelligence.

Recent developments in neural networks and deep learning approaches have immensely advanced the performance of state-of-the-art visual recognition systems. Let’s look at what are the five primary computer vision techniques.

Image Classification

Image clarification comprises of a variety of challenges, including viewpoint variation, scale variation, intra-class variation, image deformation, image occlusion, illumination conditions, and background clutter.

Computer vision researchers have come up with a data-driven approach to classify images into distinct categories. They provide the computer with a few examples of each image class and expand learning algorithms. It looks at the bars and learns about the visual appearance of each type. In short, they first accumulate a training dataset of labelled images and then feed it to the computer to process the data.

Convolutional Neural Networks (CNNs) is the most famous architecture used for image classification. An average use case for CNNs is where one feeds the network images, and the network categorises the data. CNNs tend to start with an input “scanner” that isn’t intended to parse all the training data at once. For instance, to input an image of 100×100 pixels, one wouldn’t want a layer with 10,000 nodes.
