- W2048364940 abstract "The huge data volume of hyperspectral image challenges its transportation and store. It is necessary to find an effectivemethod to compress the hyperspectral image. Through analysis and comparison of current various algorithms, a mixedcompression algorithm based on prediction, integer wavelet transform and embedded zero-tree wavelet (EZW) isproposed in this paper. We adopt a high-powered Digital Signal Processor (DSP) of TMS320DM642 to realize theproposed algorithm. Through modifying the mixed algorithm and optimizing its algorithmic language, the processingefficiency of the program was significantly improved, compared the non-optimized one. Our experiment show that themixed algorithm based on DSP runs much faster than the algorithm on personal computer. The proposed method canachieve the nearly real-time compression with excellent image quality and compression performance." @default.
