Abstract	This paper introduces a method about the improvement of JPEG2000 in retaining texture of image by using the transform of bandelet. The contours and textures of image are usually the important elements, especially in remote sensing image. However these textures are lost when JPEG2000 is used in the condition of large compression ratio. In this paper, bandelet is used to improve JPEG2000 because of its compatibility with JPEG2000. Wavelet coefficients are partitioned to a lot of code-blocks in JPEG2000. And these code-blocks naturally act as the units of the bandelet transform in this paper. And then some tricks are applied in the follow steps. Experiments show that with modifications mentioned above, more detail information is retained compared to JPEG2000. In addition, the peak signal noise ratio (PSNR) of image gains a little by using bandelet in compression process.
