In this paper, we present a new compression method for color document images based on the wavelet transform and fuzzy picture‐text segmentation. This approach addresses a fuzzy picture‐text segmentation method, which separates pictures and texts by using wavelet coefficients from color document images. The picture components and the text components are encoded by zerotree wavelet coding and by the modified run‐length Huffman coding, respectively.
