PPT-Filtering Techniques and spatial filter types

3 Filtering Filtering image data is a standard process used in almost all image processing systems Filters are used to remove noise from digital image while keeping the details of image preserved . Convolution is a general purpos e filter effect for images Is a matrix applied to an image and a mathematical operation comprised of integers It works by determining the value of a central pixel by adding the weighted values of all its neighbors tog Stacy Morgan.
