Hi all, There are a number of free tools for image matching but it's not very easy to decipher the actual algorithm from the code that includes db management, GUI, etc, etc. I have my own image database and GUI so all I need is the actual algorithm preferably in pseudo code and not in the form of a research paper (from which I also found a lot but since I'm not that much interested in the actual science of image recognition this seems like an over kill).
My understanding of image matching is that it works by first calculating N real numbers for an image and defining a metric for pairs of N-tuples. Images are similar if their distance (defined by the metric) is small. The various free tools differ by their chosen optimization paths and their degree of specialization. My preference would be, 1. Doesn't really matter how long it takes to compute the N numbers per image 2. Lookups should be fast, consequently N should not be too large (I guess) 3. It should be a generic algorithm working on generic images (everyday photos) 4. PIL should be enough for the implementation So if anyone knows of a good resource that is close to being pseudo code I would be very grateful!
