Image Coding and Compression with Sparse 3D Discrete Cosine Transform
In this paper, an algorithm for image coding based on a sparse 3-dimensional Discrete Cosine Transform (3D DCT) is studied. The algorithm is essentially a method for achieving a su...

Video Coding using 3-D Anisotropic Dual-Tree Wavelet Transform
This paper investigates the use of the anisotropic 3-D dualtree discrete wavelet transform (DDWT) for video coding. The 3-D DDWT is an attractive video representation because it i...

3d Medical Image Compression Based On Multiplierless Low-complexity Rklt And Shape-adaptive Wavelet Transform
A multiplier-less low complexity reversible integer Karhunen-Lo?ve transform (Low-RKLT) is proposed based on multi-lifting. Conventional methods based on KLT suffer from high comp...

Anisotropic 3-D wavelet packet bases for video coding
Video coding algorithms based on 3-D wavelet transforms exist which have a competitive rate-distortion performance and are very fast because motion compensation is not needed. The...

3D Computation of Gray Level Co-occurrence in Hyperspectral Image Cubes
This study extended the computation of GLCM (gray level co-occurrence matrix) to a three-dimensional form. The objective was to treat hyperspectral image cubes as volumetric data s...
