Finding Contours in OpenCV? http://stackoverflow.com/questions/8449378/finding-contours-in-opencv I want to retrieve the INNER contours. However when I use findContours I only seem to be getting the outer contours. How would I retrieve.. therefore only suggest functions that use the C API. i.e. findContours rather than cvFindContours Thanks. c image image processing.. cout Image file not found n return 1 Prepare the image for findContours cv cvtColor image image CV_BGR2GRAY cv threshold image image..
