WebThe process of performing convolution with kernel having anchor point of a particular shape in a given input image is called dilate () function in OpenCV. The dilate () function starts with computing the minimum pixel value by overlapping the kernel over the input image. And then the image is replaced by the kernel anchor at the center. http://www.opencv.org.cn/opencvdoc/2.3.2/html/modules/imgproc/doc/filtering.html?highlight=filter2d
