Abstract:

Using the spatial and spectral correlation within the hyperspectral images, a lossless compression algorithm is presented. Band grouping is used to divide images into different groups. Different hybrid integer transform based on spatial/spectral correlation is taken for each group and to achieve progressive bit-stream, coefficients are reorganized to obtain the same structure as wavelet transformation. Transformation coefficients are then coded by bit-plane-based 3D-SPIHT coding algorithm. Experimental results show that the proposed method can remove the spatial and spectral redundancy more efficiently than JPEG-LS, JPEG2000 and the algorithms based on integer 3D-DCT or 3D-DWT. With band grouping and progressive bit-stream, the proposed method can achieve better error resilient performance.
