In this paper, we propose a simple but efficient lossless compression scheme for compound images. For natural image region in compound image, we introduce an efficient context modeling scheme, with reduced complexity in context modeling. Then, a block skip method is adopted to effectively express homogeneous regions. We also incorporate a pattern run-based representation for graphic regions. In the experiment, the proposed scheme outperforms JPEG-LS [1] and JPEG-XR [2] by 1.4 times and 2.9 times, respectively.
