Content-based image retrieval

Content-based image retrieval is a way of finding specific images in a group of photos. It works by looking at the details and colors inside the images and comparing them to a list of things we want to find. For example, if you search for "dog", content-based image retrieval will look through all the pictures and find the ones that have the most details and colors of a dog.
