Image Nudity Filter

Image Nudity Filter is a PHP class that can be used to determine whether an image may contain nudity. It analyzes the colors used in different sections of an image to determine whether those colors match the human skin color tones. As a result of the analysis, it returns a score value that reflects the probability of the image to contain nudity. Additionally, it can output the analysed image, marking the pixels with color skin tones with a given color. It can analyze images in the PNG, GIF, and JPEG formats.
