| Summary: | The development of television systems is an important factor for many industries
involved in the acquisition, processing, storage and transmission of images. Today,
an urgent task in the use of such systems is to improve the quality of images
obtained using digital photo and video cameras. To solve this problem, digital
recursive-separable smoothing filters can be used. The paper describes the process
of operation of the algorithm for changing the size of the scanning multi-element
aperture of a smoothing trapezoidal recursive-separable filter for digital image
processing. The results of evaluating its performance relative to the same algorithm
implemented through classical two-dimensional convolution for various sizes of test
images are presented. The influence of the aperture size of the developed filter on
the change in the signal-to-noise ratio is assessed. The algorithm is implemented in
the MATLAB computing environment. |
