Annotation:  This paper reveals existing methods for estimating image quality. Existing methods do not give ability to get absolute score for image quality. The main goal of the study is proposing of new effective method for evaluation of image quality. This method is based on well-known criteria for evaluation of image quality with the use of the information criterion of homogeneity. Image quality can be estimated with following criteria: brightness, contrast and tone saturation. By themselves criteria give information about general properties of image – those methods cannot be used for comparison. This paper proposes to use degree of change for criteria instead of using criteria itself. Offered method can be used for automatic selection of images for further processing. Console application was developed for experimentation with offered method with use of C++ programming language and computer vision framework OpenCV. Results of this experimentation proved high performance and effectiveness of evaluation of image quality with proposed method

Keywords:  evaluation of image quality, homogeneity, degree of change for criteria, degree of change for brightness
