Kernel is a matrix that is generally smaller than the image and the center of the kernel matrix coincides with the pixels. In a 2D Convolution, the kernel matrix is a 2-dimensional, Square, A x B matrix, where both A …

WebIn image processing, a convolution kernel is a 2D matrix that is used to filter images. Also known as a convolution matrix, a convolution kernel is typically a square, MxN matrix, where both M and N are odd integers (e.g. 3×3, 5×5, 7×7 etc.). See the 3×3 example matrix given below. (1) A 3×3 2D convolution kernel. 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.
