WebThe implementation of filter on an image is achieved by applying a suitable mask, or kernel, and performing the convolution operation. The high-boost filtered image can be obtained by convolution with masking kernels H B represented as follows: Where w = A + 4 and w, = A + 8. Figure 5.5 shows two types of mask to achieve high-boost filtering.
