AB  - Demosaicing is a process of obtaining a full
color image by interpolating the missing colors of an
image captured from a digital still and video camera that
use a single-sensor array. To compress the demosaiced
images, conversion from RGB to YCbCr format is
required. This is a method in which a non adaptive
interpolation is used to reduce the complexity of the
technique which directly produces YCbCr format from
mosaic image, i.e., raw single sensor array digital camera
image. During computation of chrominance samples, the
green channel is omitted to reduce the complexity because
the green channel has minimal impact on the quality of
chrominance channels. This technique saves considerable
computational complexity by avoiding the need for
performing demosaicing in RGB space and then
converting from RGB to YCbCr 4:1:1. As compared with
the recent demosaicing algorithms, the proposed
algorithm produces the best demosaicing performance in
YCbCr format with respect to mean square error. This
approach outperforms other methods in-terms of no of
operations per pixel.
