i want to compare an algorithm of edge detection with others using pratt's FOM or f measure..... any good links to start studying from??

 

The way you have asked the question, the only people that can answer it are people that are conversant with BOTH, MatLab and Pratt's FOM (whatever that is). Are you having problem with just one and not the other? If so and if you understand Pratt's FOM and are just having problems with implementing it in MatLab, throw us a bone and describe the key aspect of Pratt's FOM as it relates to edge detection so that someone that is familier with MatLab and not with Pratt's FOM has a chance of being able to help you. Otherwise, you are limiting youself to a pretty narrow pool of potential responders (none of whom might be a member of this forum).
