Opencv prewitt c++
Did you know?
One thing to know about a Prewitt operator is that it is separable. See the Wikipedia article for details. To calculate a single output row, you need to do the following (pseudocode): int* buffer = malloc (sizeof(int) * width); for (int i = 0; i < width; i++) { // Do the vertical pass of the convolution of the first 3 rows into ...
