WebFeb 15, 2024 · This might help you to understand how a kernel can blur a image. Every single pixel in the final output is a combination of the 9 pixels from the input image that are covered by the kernel matrix. Look back at the first image in the blog post. Using ‘kernel_blur’ the green number in the output matrix will be equal to 6 * 1/9 = 0.66. WebThe Fisher kernel can thus be viewed as a distance measure between the descriptor values of each image based on the mutual information of the prior classes’ descriptors distribution.
