Adaptive Image Demosaicing Algorithm for Artifact Suppression

Abstract

newlineOwing to the rapid advancements in technology as well as the easy availability of digital cameras and mobile phones, the usage of images and videos has increased manifolds in the various regimes such as education, healthcare, surveillance, etc. Despite the technological advancements, there is still need to improve the quality of an image as it is dependent on various factors ranging from features of cameras such newlineas its resolution, sensitivity to light, sensor s dynamic range, etc. to the conditions that occur while capturing the images such as adjustment of white balance, focus adjustment, color interpolation, color correction, compression, etc. However, Color Filter Array (CFA) interpolation is an indispensable part of image pipeline which is used to recover full resolution image from its CFA data. The requirement of CFA in color images is that there must be a minimum of three color samples at pixel location. newline
