Remote Sensing Image-oriented JPEG2000 Optimized Compression Algorithm
Based on the frame of conventional JPEG2000 compression,a segment treatment compression algorithm is put forward to solve the problem of time-consuming processing of remote sensing image. In the coding channel,the scanning stage is combined with the coding stage,so the time of the coding and deciphering process is reduced. After wavelet transformations,unimportant background information of the wavelet coefficient in high frequency sub-bands is eliminated and the handling process of important information is shortened,so the transmission time which has much correlation about compression ratios and data volume can be reduced significantly. Experimental results show the time of the remote sensing image compression,transmission and reconstruction of this algorithm can be shortened without image quality reduced.
