In this paper a lossless compression method for hyperspectral image is given. RKLT-based scheme was first presented by combining with 3D prediction, principal component selection, positive mapping followed by a range coder. The proposed method avoids the float number of coefficient which can make it much more easier to be processed on hardware. Numerical experiments show that the proposed method outperforms...
In this paper, an efficient method for Hyperspectral image compression based on the Tucker Decomposition (TD) and the Three Dimensional Discrete Cosine Transform (3D-DCT) is proposed. The core idea behind our proposed technique is to apply TD to the 3D-DCT coefficients of Hyperspectral image in order to not only exploit redundancies between bands but also to use spatial correlations of every image...
We proposed a new transform scheme of multiplierless reversible time-domain lapped transform and Karhunen-Loeve transform (RTDLT/KLT) for lossy-to-lossless hyperspectral image compression. Instead of applying discrete wavelet transform (DWT) in the spatial domain, RTDLT is applied for decorrelation. RTDLT can be achieved by existing discrete cosine transform and pre- and postfilters, while the reversible...
