Hi, I wrote software to do something like this a long time ago, when I worked at a usenet provider an we needed to track spam images. I broke each image down into smaller square images, and downsampled each to 8 bit, then calculated a "color average" of all the pixels in each sample. If one image matched enough samples to another image they were considered the same. It didn't work for what i needed though, because it would find similar images (a person moved an arm, but everything else was the same for example). Unfortunately, I don't have the source available.

hi guys, does anyone know anything about querying images? for example, i have a database with images files (.jpg for example), and i have another image (for example my gmail picture), i want to search images similar or "near" to my image
some points that i'm thinking about... images have many data, including meta data, maybe not only querying images (faces for example) but search a barcode or a ocr text, and many others features (i know some features when i worked with some opencv projects)
ideas and informations and experiences are wellcome :)
