They all should have the same depth, CV_8U or CV_32F , and the same size. This book will also provide clear examples written in Python to build OpenCV applications. /* This program demonstrates how to use OpenCV PCA with a. But consider, what if you need not find the number of pixels for all pixel values separately, but number of pixels in a interval of pixel values?
