| Abstract: | Because of limited storage and huge image data of VDR radar image, it is hard to deliver and store images. The integer wavelet transform and improved SPECK are syncretized. The image is transformed by integer wavelet first, then SPECK is used to code, and due to synthetical matching and Hash table are brought in, SPECK is improved. By radar image compression, it can improve not only compression speed but also compression rate, and its application is wide. |
| Keywords: | integer wavelet transform SPECK fast and lossless compression |
