Embodiment Construction
[0040] The inventive idea of the present invention is: the principle composition of the hyperspectral image compression and reconstruction device and method of the present invention is as follows figure 1shown. The present invention adopts the distributed information source coding strategy. Firstly, each spectral segment of the hyperspectral image is subjected to three-level two-dimensional 9 / 7 integer discrete lifting wavelet transform; secondly, the wavelet coefficients are organized into segments and blocks by using the CCDSD-IDC method, And encode the segment header information, DC coefficient initialization and AC coefficient depth of each block, and extract the AC coefficient and the remaining DC coefficient bit plane at the same time; finally, use the LDPC-based Slepian-Wolf encoder to realize the AC coefficient and the remaining DC coefficient bit plane Distributed source coding.
[0041] The present invention will be described in detail below in conjunction with th...
