Abstract
We 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 wavelettransformed images. On test images, our adaptive coding algorithm is shown to give compression effectiveness comparable to the best performance achievable by an alternate algorithm that has been previously implemented.
