WebImplementation of the Fisher Kernel Framework for Image Retrieval Implementation based on the article “Large-scale image retrieval with compressed fisher vectors” … 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 (including itself) in the input image, the kernel is that function.
