baically i would like a class which i can use for many purposes, it should work like so: 1) photo is analyzed, face is detected. 2) many different ratios are calculated, e.g between the eyes and circumference, between the mouth and bottom of head and mouth of bottom of head. 3) there should be many of these done. Then texture should be analyzed and tone, of skin and eyes. 4) the algorythyms should then generate a code, which contains all this data. This will enable me for example to create a social network where users create accounts upload a photo, which has a code generated for it and then when they upload more photos they can have codes generated for them and if the codes match the users or any of their friends codes they can be automatically tagged. I am not looking for these codes to be completely unique and would expect them to be unique for 1 in every 100 thousand. As well as creating the class i would like you to create a simple user account creator and image uploader which automatically tags photos.
