Image Filtering Using Convolution in OpenCV - GeeksforGeeks

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. WebMay 1, 2024 · Abstract. Image filters have wide spread use in Image processing.
