This approach includes two steps: Discrete Wavelet Transform (DWT) and Modified Run Length Encoding (MRLE). The former used CDF9/7 biorthogonal wavelet filters to powerfully get rid of correlation between pixels in imagery. The later put enlightening information into the lowest bit of some key-position transform coefficients. Consequently  CDF9/7 and MRLE together make hardware platform remain high real-time capability  and help reconstructed images keep good fidelity with PSNR being about 40dB  compared with the original ones. Comparison between experimentations on SPOT4's low-spatial-resolution (10m) imagery and Ikonos2's high-spatial-resolution (1m) imagery  shows this "DWT+MRLE" method having better performance for remote-sensed imagery  especially those of higher resolution. Although inferior to 8:1  Compression Ration (CR) here near 5:1 is greater than France SPOT5's 3:1 and American Ikonos2's 11:2.6 on-board data compression. More important  this method having less computational amount is good for spaceborne capability of real time. The consumed time of different image size is also presented in this paper  based on TI TMSC6416 DSP chip with 600MHz CPU cycle clock.   A black box that contains information about installation of vertical oil pipe's righting-lifters 会议论文 Conference on Machine Tool, In-Line, and Robot Sensors and Controls, OCT 25-26, 1995 作者:  Chen, WY;  Wu, FT;  Lu, JH;  Li, P 收藏  |  浏览/下载：3/0  |  提交时间：2019/12/31 oil pipe  righting-lifter  installation  self-adaptive  run-length  encoding
