Opencv python integral

dev = sqrt ( (C'+A'-B'-D')/4 - (mean*mean)) So computing mean and dev using integral image is very fast using integral images, especially if you want to compute those quantities at random locations and on random size of image patches. Concerning the gradient, it's more complex. WebOpenCV comes with a predefined function to calculate an integral image. void cvIntegral(const CvArr* image, CvArr* sum, CvArr* sqsum=NULL, CvArr* tilted_sum=NULL); The parameters are, as always, self explanatory: image: the source image sum: the sum summation integral image sqsum: the square sum integral image
