Convolution is a mathematical operation which apply a kernel to transform input. Let the input be a matrix (representing an image for example). A kernel is a small matrix that act like a filter that transform a part of the image via multipl Caution and addition to derive a final number as output. The kernel is applied from the top left of the matrix? Slide one number to the right each time until it is applied to the entire matrix. The output “enhanced” certain feature in the matrix in the output matrix.
