Spatially-Aligned Chroma from Luma Prediction for Lossless JPEG XS Raw Image Compression
Taizo Suzuki, Soma Yokota, Masaki Onuki
This study proposes a Chroma from Luma (CfL)-enhanced Star-Tetrix transform (STT), referred to as CfL-STT, for improving raw image compression in JPEG XS. The proposed CfL-STT inte…
Lightning-Fast Dual-Layer Lossless Coding for Radiance Format High Dynamic Range Images
Taizo Suzuki, Sara Yukikata, Kai Yang +1
This paper proposes a fast dual-layer lossless coding for high dynamic range images (HDRIs) in the Radiance format. The coding, which consists of a base layer and a lossless enhanc…
Edge-Aware Extended Star-Tetrix Transforms for CFA-Sampled Raw Camera Image Compression
Taizo Suzuki, Liping Huang
Codecs using spectral-spatial transforms efficiently compress raw camera images captured with a color filter array (CFA-sampled raw images) by changing their RGB color space into a…
Directional Analytic Discrete Cosine Frames
Seisuke Kyochi, Taizo Suzuki, Yuichi Tanaka
Block frames called directional analytic discrete cosine frames (DADCFs) are proposed for sparse image representation. In contrast to conventional overlapped frames, the proposed D…
