Abstract :
To obtain a true color image from the Bayer CFA samples, an estimation process using interpolation is performed to retrieve the missing color components of each pixel. This is commonly referred to as CFA demosaicing. In this paper, we study the relationship between the resolution of the acquired CFA image and the quality of the demosaiced color image. For this purpose, we propose new criteria based especially on the detected edges of the objects present in the scene.
