Everything about Kernel (image processing)

Matrix used in image processing to alter an image

In image processing, a kernel, convolution matrix, or mask is a small matrix used for blurring, sharpening, embossing, edge detection, and more. This is accomplished by doing a convolution between the kernel and an image. Or more simply, when each pixel in the output image is a function of the nearby pixels in the input image, the kernel is that function. Wikipedia →
