Web20 de jun. de 2013 · The OpenCV documentation seems to be very clear: src – input 1-, 3-, or 4-channel image; when ksize is 3 or 5, the image depth should be CV_8U, CV_16U, or CV_32F, for larger aperture sizes, it can only be CV_8U. As you need to cater for signed values, I think your best option is to use CV_32F. Also, the documentation says.
