Зменшення рівня спотворень векторних зображень внаслідок вбудовування цифрових водяних знаків

Abstract

An analysis of the existing methods for embedding digital watermarks (CECs) shows that for most of them, the problem of impairment of image quality in the embedded CMS is actualy. When displaying real objects on a scale (architectural structures, geographic maps, etc.), this problem is especially relevant, since a significant change in the coordinates of the points can significantly impair the quality of information about existing objects or affect their creation. On this basis, the advantages and disadvantages of existing methods of embedding the CMS in vector images are analyzed, and one of the known methods is optimized by reducing the image-container distortion.
