I am developing a matlab code for the problem. I have a idea but would like to improve it and therefore would want to ask for opinions. We are given a jumbled up image of a human face. We have to arrange the face back into place. We will be shown and given the randomized image. The randomized image in general will comprise of parts(p's) 20(4X5,4X4...) parts. Dont expect it to be many. My idea. I will use the face that the from face of an individual is symmetrical. Therefore i plan to take the p's and place them in random order, and check for symmetry. In brief i will take left hand side of image-right hand side of image. Calculate deviation and i will set the treshold value. Any idea which iseasier to implement. I myself am not understanding how to make the code for doing the above. Any reference websites that i can read and get something read.
