AN EFFICIENT SUPER RESOLUTION TECHNIQUE FOR LOSS LESS COMPRESSED BAYER COLOUR FILTER ARRAY IMAGES
Journal Title: International Journal on Computer Science and Engineering - Year 2011, Vol 3, Issue 5
Abstract
In digital cameras, Bayer color filter array(CFA) images are captured and demosaicing is carried out before compression. Recently, it was found that compression-first schemes outperform the conventional demosaicing-first schemes in terms of output image quality. An efficient prediction-based lossless compression and super-resolution schemes are proposed in this paper. Compressed image is coded with rice code. The proposed compression and super resolution schemes can achieve a better compression and high image quality than conventional lossless CFA image coding schemes.
