Answer 1

It depends on the image and what you want to find. Usually when people ask for image processing advice they attach an image. You didn't do that so all I can do at this point is to point you to my File Exchange http://www.mathworks.com/matlabcentral/fileexchange/?term=authorid%3A31862 which showcases a very very small number of the thousands of methods available to you, and to the Vision Bibliography http://iris.usc.edu/Vision-Notes/bibliography/contents.html which lists practically every image processing article ever published.
