Quality-efficient demosaicing for digital time delay and integration images using edge-sensing scheme in color difference domain

Universal Chroma Subsampling Strategy for Compressing Mosaic Video Sequences With Arbitrary RGB Color Filter Arrays in H.264/AVC

“…Chen et al's method can produce significant enhancement in the quality of the reconstructed mosaic video at both the cases of high and low bitrates when compared with a conventional method in H.264/AVC, leading to a pioneer achievement in compressing Bayer CFA video sequences. Then, Chung et al [10] extended the chroma subsampling method to deal with the digital time delay and integration (DTDI) CFA video sequences [3], [37], which is captured by line-scan cameras based on the Bayer CFA structure and field programmable gate arrays. Since these existing compression methods are specifically designed for mosaic sequences with the Bayer CFA-related structures, they cannot be used directly for compressing mosaic video sequences with different CFA structures due to the constraint on the mosaic structure.…”
