Abstract

In many digital color-image systems, most notably digital cameras, raw data from the sensor is processed to produce a pleasing image. One of the main steps in this process is demosaicing, which is the process of interpolating the raw data into a full color image. The resulting image is in turn compressed to enable compact storage. Each of these two steps, namely the demosaicing and compression, creates its own artifacts on the final image. In this work we consider the two stages together, and design a demosaicing algorithm which takes into account the fact that the final image is to be compressed. Examples are given to demonstrate the above ideas.
