High boost filtering method
WebAbstract. A partial differential equation (PDE) based technique is proposed and implemented to perform unsharp masking, crispening and high boost filtering of digital images. The traditional concept of unsharp masking and crispening of edges which uses Laplacian as intermediate step for smoothening the image has been extended and modified using ...

WebHigh-boost filtering can be implemented with one pass using either of the two masks shown in Fig. 3. Note that, when A=1, high-boost filtering becomes “standard” Laplacian sharpening. As the value of A increases past 1, the contribution of the sharpening process becomes less and less important. Eventually, if A is large enough, the high ...
