Abstract :
This paper introduces an artificial neural networks (ANN) based framework for joint demosaicing of color field array (CFA) raw image sequences. We propose an algorithm that offers superior resolution, signal to noise ratio and dynamic range when compared to single-frame demosaicing. A rich set of both synthetic and real world experimental results illustrates its capabilities.
