Applied Problems of Digital Image Processing: Resampling of the Raster Image

Image secondary sampling (resampling) is one of the most important procedures applied to many digital image-processing procedures. Notwithstanding the image secondary sampling is a basis for a trivial, in non-technical language, rescaling or image rotation in digital printing or in digital TV, however available literature lacks detailed and integral description of the processes that would allow for changing image sampling rate or image sampling structure from one to another value. In this paper, a shot was made at closing the gap. The monograph contains three chapters stating the algorithms of image sampling rate conversion, the technique of interpolation of a TV image with splines of the third and fifth degrees, and the technique of restriction of the width of the two-dimensional spectrum of an image performed in the digital low-pass filter before decreasing this image sampling rate are developed.
