The problem of crosstalk between different color bands was seemingly overlooked by existing color demosaicking algorithms. In this paper we propose a new joint demosaicking and decrosstalk technique that corrects channel crosstalks by adaptive least-squares inverse filtering. The new technique integrates the operations of deconvolution for crosstalk removal and interpolation for color demosaicking,...
Single-sensor digital cameras capture images by covering the sensor surface with a color filter array (CFA) such that only one color sample is taken at the location of each pixel. To render a full-color image, color CFA interpolation or demosaicing using neighboring samples as a very important part of video/image processing, is required to estimate values of the other colors at each pixel. However,...
