I have to identify and catalog geometric perfumes. such as the following images: The images will always be scanned in black and white, and the actual size. and will always consist of geometric forms, such as circumferences, rectangles, ellipses ...
The idea is to find similar profiles, that is given another profile, search the ones I have cataloged and present them by level of similarity.
Is there any way to develop an algorithm for this? Where do I start? links to documentation Domino PHP; ASP ^ and C and I have a visual basic ideas.
