Many tasks of computer vision produce a histogram and the program must decide whether there is a distinct peak on it, then calculate its parameters such as the height and exact location. This may be tricky. For example if the peak is asymmetrical, taking the maximum may shift location substantially. Another problem is local peaks which should be ignored. I encountered this task in areas not related to vision. Say, in spectroscopy. So there should be extensive research into possible approaches. Can anybody recommend resources for reading?
