Generalized Golomb Codes and Adaptive Coding of Wavelet Transformed Image Subban

IPN Progress Report 42-154 August 15, 2003Generalized Golomb Codes and Adaptive Coding of Wavelet-Transformed Image SubbandsA. Kiely1 and M. Klimesh1We describe a class of prefix-free codes for the nonnegative integers. We apply a family of codes in this class to the problem of runlength coding, specifically as part of an adaptive algorithm for compressing quantized subbands of wavelet- transformed images. On test images, our adaptive coding algorithm is shown to give compression effectiveness c
