For some reason, beginners want to do edge detection on everything as a first step. So read the link Walter gave and then post your image and tell us what you want to measure and we'll tell you if edge detection is even appropriate, or the best method. Perhaps simple thresholding is what you need - we'll never know unless you share your image and your desired measurements.
