Abstract :
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 a dense pixel map for each spectral component. We present two new color interpolation techniques with low buffer requirements for processing while developing color images with very good quality. We also present a comparative study with other interpolation techniques of similar buffer requirements
