Lightning-Fast Dual-Layer Lossless Coding for Radiance Format High Dynamic Range Images
To suppress the dynamic range of the residuals in the enhancement layer, the coding directly uses the mantissa and exponent information from the Radiance format.
Edge-Aware Extended Star-Tetrix Transforms for CFA-Sampled Raw Camera Image Compression
Compared with XSTTs, the EXSTTs can decorrelate CFA-sampled raw images well: they reduce the difference in energy between the two green components by about $3. 38$--$30. 08$ \% for high-quality camera images and $8. 97$--$14. 47$ \% for mobile phone images.
Regularity-Constrained Fast Sine Transforms
In contrast, the proposed regularity-constrained fast sine transform (R-FST) is obtained by just appending a regularity constraint matrix as a postprocessing of the original DST.
Directional Analytic Discrete Cosine Frames
Block frames called directional analytic discrete cosine frames (DADCFs) are proposed for sparse image representation.
