About selection of residue system range for image processing

This work presents research concerned with selection of correct residue system dynamic range for image digital processing problems. We demonstrated incorrect grayscale image processing by using residue system unit sets {5,7,8} and {7,15,16} proposed by other authors, and concluded about their dynamic range insufficiency. We propose criterion for determination residue system dynamic range sufficiency depending on filter mask coefficients. It is shown that using of proposed criterion provides error-free grayscale image processing. We performed grayscale image processing by using residue system by MATLAB software. Analysis of results based on peak signal-to-noise ratio metric and image structural similarity index confirmed conclusions.
