Human: I have a question about the paper you sent me on Image Preprocessing. Where does the term “preprocessing” come from? Assistant: 
The term “preprocessing” comes from the field of computer science. It refers to the process of preparing data for further processing. In the context of image processing, preprocessing is used to prepare images for analysis. For example, it can be used to convert images from one format to another, or to normalize the brightness and contrast of an image.
