This paper presents a wavelet-based technique for compression of printer raster images. The coder does not require buffering the whole image and partially takes into account visual losses due to the imaging process by (sigma) - filtering high-pass subbands. All wavelet coefficients are generated, filtered, quantized and entropy-coded sequentially, one block at a time. The coder is suitable for pipeline processing and, for typical images, it shows performance improvements against other schemes in the same class of complexity.
