| Abstract: | This paper considers novel lossless compression of black and white images by applying recently developed turbo compression techniques. An empirical study of image pixel statistics is initially conducted in order to enable distributed turbo compression of image rows. In particular, it is noted that while the entropy of the pixels throughout the image does not vary much, the distribution and conditional distributions of pixel values are non-stationary. Corresponding compression bounds are noted, appropriate coding schemes based on turbo-codes are developed and simulation results are reported. | ||
