Why Machine Vision Is Flawed in the Same Way as Human Vision

The pathway in the brain responsible for vision operates in several layers, each of which is thought to extract progressively more information from an image, such as movement, shape, color, and so on. Each layer consists of huge numbers of neurons connected into a vast network. Deep convolution neural networks have a similar structure. They too are made up of layers, and each of these is a network of circuits designed to mimic the behavior of neurons, hence the term neural network. Through much trial and error, computer scientists have found that these layers perform best when each extracts progressively more information about an image. And when they look at the behavior of layers individually, they find remarkable similarities to the function of specific layers in the brain.
