Abstract

The article is devoted to the development of a digital image compression algorithm. Image compression is a type of data compression applied to digital images, to reduce their cost for storage or transmission. Algorithms may take advantage of visual perception and the statistical properties of image data. We will consider a lossy compression algorithm that is based on multi-scale analysis using a spline as a basis function. An algorithm for compressing image data with an adaptive calculation of detail coefficients has been developed. Its advantages and prospects of use for the image compression in the online communication are considered. The application of this approach give an increase in the compression ratio with the same quality of compressed images.
