Efficient Color Image Compression Using Demosaicing
Evgeny Gershikov, Moshe Porat · 2010
In this work we introduce a new algorithm for color image compression based on inter-color correlations of the RGB (red, green and blue) primary colors of images and video. We employ the Bayer pattern, widely used in digital cameras and mobile phones, for its compression software. Our proposed method outperforms JPEG2000 for all the images tested, with a gain of more than 1dB in peak signal-to-noise ratio (PSNR) on average. Our conclusion is that the new algorithm could be useful in efficient visual communication.
