Demosaicing and Lossless Compression Techniques

Digital cameras have become popular, and many people are choosing to take their pictures with digital cameras instead of cameras using films. The combination of a single Charge Coupled Device (CCD) sensor with a Color Filter Array (CFA) remains the predominant implementation inside the digital cameras for capturing color images. When a digital image is recorded, the camera needs to perform a significant amount of processing to provide the user with a viewable image. This processing includes correction for sensor non-linearity, non-uniformities, white balance adjustments, compression and more. An important part of this image processing chain is color filter array interpolation or demosaicing
