Abstract :
New piecewise-linear basis functions called PLh functions are proposed. Using the PLh functions a new digital signal processing transform. The PLh transform, is derived. The PLh transform has an attractive feature of economy of computational effort both in computation time and in storage size. Thus the new transform is suitable for image processing and other applications in which a large number of data need to be processed. Application of the PLh transform to edge detection of a two-dimensional image is also discussed
