In digital color imaging, color filter arrays (CFAs) are obtained from single chip cameras in the form of sampled spectral components (red, green and blue) in an interleaved fashion. Color demosaicing is the process of interpolating these color filter arrays (CFAs) into the dense pixel maps for each spectral component. There are different interpolation techniques for color demosaicing operations. These approaches have their limitations regarding the improvement of the quality of the images. They perform poorly in recovering the edges of the images. In this work we have applied Markov Random Field (MRF) processing over these roughly interpolated images to improve the quality of the reconstruction. We have observed that the processing improves the image quality in many cases. The edges of the reconstructed images are significantly enhanced using MRF processing. download full paper
