To detect the dominant points within an image first we must find the edges. In this example the edges are found using cvFindContours. The resulting contours are then processed to find the dominant points along the contour. This is done using the cvFindDominantPoints function, this function implements the IPAN99 algorithm… Read more »

Splitting multichannel images into RGB using OpenCV

To separate a multi channel image into the three component RGB channels, we can use the cvSplit function. The example below opens a RGB image and then using the cvSplit function creates three output images. #include “stdafx.h” #include “cv.h” #include “highgui.h” int _tmain(int argc, _TCHAR* argv[]) { // open and… Read more »
