This paper presents a combined halftoning and compression approach, which achieves high quality halftones and compression ratios comparable to those of JBIG with much simpler encoding and decoding schemes. In the proposed algorithm, we halftone the input continuous-tone image with constraints in a controlled manner, so that we can decrease the entropy of the resulting halftones while maintaining a high level of visual image quality.
