WebLINEAR SPATIAL FILTERING A linear spatial filter performs a sum-of-products operation between an image and a filter kernel, . The kernel is an array whose size defines the neighborhood of operation, and whose coefficients determine the nature of the filter. Other terms used to refer to a spatial filter kernel are mask, template, and window. WebDigital filters, however, are not the answer to all signal processing filtering requirements.
