Abstract:

Applicable for digital cameras equipped with single-sensor covered with a color filter array (CFA), a new joint color demosaicking and zooming algorithm was proposed, the interpolation directions from the raw CFA image was estimated based on the local gradients. The estimated directions were exploited consistently in the demosaicking and zooming. Experiments show that the proposed algorithm is of good performance compared with the several recently published algorithms.

Key words: demosaicking, interpolation, zooming, color filter array
