What is convolution in 2D?
Image is denoted as matrix inside computer. An image contains a lot of features like edge, contrast etc. In image processing features have to be extracted from the image for further study of image.
Convolution is a fundamental operation on images in which a mathematical operation is applied to each pixel to get the desired result.
For this purpose, another matrix called as kernel is used which is smaller in size of image. This is also called filter. This filter is applied on each pixel of the image and new value obtained is the value of that pixel. The image obtained is called filtered image.
In kernel each cell contain some value, that kernel is kept above the pixel and corresponding values are multiplied and then summed up this value obtained is new the value of pixel.
