RESEARCH OF LOSSY IMAGES COMPRESSION METHOD WITH APPLICATION OF ADAPTIVE QUANTIZATION
Annotation
The method of values calculation of a quantization vector factors for lossy compression schemes of images, based on using the weight criterion is offered. Comparison of base JPEG scheme and its modification on the basis of the developed method is made. The given modification exceeds JPEG scheme on 10-20 %. Generalization of the method is made for compression schemes on the basis of adaptive segmentation.
