Abstract :
In this paper an image data compression scheme based on the periodic Haar piecewise-linear (PHL) transform and quantization tables is proposed. Effectiveness of the compression for different classes of images is evaluated. The comparison of the compression quality using PHL and DCT transforms is given.
