Abstract

This paper discusses the constructing method of a general integer wavelet transform algorithm. Coupling such an algorithm with subblock differential pulse code modulation (DPCM), an encoding scheme for near-lossless image compression is obtained for remote sensing images. This method possesses the following features: (1) real-time processing is possible; (2) hardware implementation is easy; (3) the algorithm is of parallel structure; (4) only addition, subtraction and bit-shift are involved in the processing. Experiments illustrate that our algorithm is an effective encoding scheme to compress remote sensing images.
