Fast algorithms for single chip video demosaicing
Jayanta Mukherjee, Sushmita Mitra · 2006
In a single-chip digital color imaging sensor, a color filter array (CFA) is used to obtain sampled spectral components (red, green and blue) in an interleaved fashion. Color demosaicing is the process of interpolating these regularly spaced sampled values into the dense pixel maps for each spectral component. In this paper we present several new algorithms for the demosaicing of CFA sequences. We have considered block processing and temporal prediction for increasing the speed of interpolation. Significant reduction in computation has been achieved, while preserving the quality of video at an acceptable level.
