Single-sensor digital cameras capture image by covering the sensor surface with a color filter array(CFA) such that each sensor pixel only samples one of three primary color values  three color is R(red)  G(green) and B(blue). To render a full-color image  need an interpolation process commonly referred to as CFA demosaicking  is required to estimate the other two contributions for producing a full-color image. But  the noise in imaging sensors not only corrupts the color filter array  at the same time introduces artifacts during the color interpolation step and influence quality of images. In order to acquire high quality full-color images  adopt a sort of viable and effective interpolation algorithm based on gradient  at the time of removing the noise  reserve image border and detail information clearly. 2012 IEEE.
