Segment tree implementation for Rangesum

电机的机械特性图，由matlab计算以及仿真得到(Mechanical characteristics of the motor map, as well as by the matlab simulation has been calculated)

recursive mean-separate histogram equalization

there is some code in matlab that will provide help in the field if digital image processing.it includes the code of extracting region of interst, median filter, nearest neighbour point sampling technique, negative of an image etc. and it is done by myself because i am doing becholar of computer science.it does not include any copyrighted content.i hope it will help thoes people that required help in the field of digital image processing.
