Filtering is just applying a mask to an image.Computer vision people call the linear form of these operations“convolutions”. They are actually “correlations,” since the true convolution inverts the mask.There aremany nonlinear filters, too, such as median filters and morphological filters.Filtering is the lowest level of image analysis and is taught heavily in image processing courses.
