根据遥感图像编码的特殊性，提出了一种感兴趣系数编码算法。
A novel image coding algorithm based on coefficients of interest is proposed in terms of the special needs of remote-sensing images.
并选择了9/7-F、9/7-M和5/3三种传统用于图像压缩的小波来用提升方法实现从整数到整数的小波，为后面进一步研究系数编码做好准备。
Then, the 9/7-F, 9/7-M and 5/3 wavelets which use generally in image compression, are selected for factoring them into lifting steps so as to study the coefficients coding.
尤其在图像编码中，少量系数的错误不会对图像的视觉效果造成太大影响。
Especially in image coding, a few coefficient errors won't influence vision effect much.
