What is computer vision used for? Is image classification computer vision?

Computer vision, or the ability of artificially intelligent systems to “see” like humans, has been a subject of increasing interest and rigorous research now. As a way of emulating the human visual system, the research in the field of computer vision purports to develop machines that can automate tasks that require visual cognition. However, the process of deciphering images, due to the significantly greater amount of multi-dimensional data that needs analysis, is much more complex than understanding other forms of binary information. This makes developing AI systems that can recognize visual data more complicated.

Image processing is, as its name implies, all about the processing of images. Both the input and the output are images. Methods frequently used in image processing are: filtering, noise removal, edge detection, color processing and so forth. Image processing methods are harnessed for achieving tasks of computer vision.
