Hi there !!

Actually I am new to the field of Digital Image processing and I have to make a project in which I have to compare any input images with those in the database and give results according to the degree of similarity. The images can be any geographical maps, faces etc. but a grayscale only at this stage. 
Can you help me to know what series of techniques I must use for the purpose. As I was thinking to apply edge detection then thresholding and after that comparison of this image. but I am not sure. Is this the best possible way? 

Thanx in advace
Warm Regards
