Abstract

In order to cut computing and time expenses during analysis of color images, in practice often the simplified models are used. For example, application of gray-scale presentations of color images in video analysis allows reducing expenses by 2-3 times. At the same time, a part of information about the original image is lost which reduces the analysis accuracy. The error of the result depends essentially on choice of functions used for gray scaling. The algorithm of shared usage of multivariate gray-scale presentations of color images providing increase of accuracy of result is proposed. The regions of practical application are indicated, in which using the proposed algorithm does not result in additional temporary costs on corresponding procedures. Illustrative examples are given.
