Abstract

The digital cameras test scenes utilize a color channel cluster of mosaic example (e.g., the Bayer example). The demosaicking of the color samples in [4] is basic to the picture essence. It displays another shading demosaicking procedure of ideal directional sifting of the green- red and green-blue contrast signals. Expecting it that the essential distinction signals (PDS) between the green and the red/blue channels are low pass, the missing green samples are robustly decided in both even and additionally vertical bearing by the direct least mean square-mistake estimation (LMMSE) procedure. These directional evaluations will be then ideally intertwined to further enhance the green gauges. In conclusion, guided by the demosaicked full-determination green channel, the other two shading channels are recreated from the LMMSE separated and intertwined PDS.
