Self-similarity Driven Demosaicking
Digital cameras record only one color component per pixel, red, green or blue. Demosaicking is the process by which one can infer a whole color matrix from such a matrix of values, thus interpolating the two missing color values per pixel. The selected color configuration of the sensor usually follows the Bayer color filter array, CFA. Out of a group of four pixels, two are green (in quincunx),...
متن کاملNovel Demosaicking Method Using Nonlocal Similarity Fusion
Although most demosaicking methods assume the existence of high local correlation in estimating the missing color components, such an assumption may fail for images with high color saturation and sharp color transitions. This paper presents a demosaicking scheme by exploiting both the variance of color differences (VCD) and the non-local similarity. First, the missing green components are estim...
متن کاملColor demosaicking via fully directional estimation
Given a natural image from the single sensor, the key task is to properly reconstruct the full color image. This paper presents an effectively demosaicking algorithm based on fully directional estimation using Bayer color filter array pattern. The proposed method smoothly keeps access to current reconstruction implementations, and outperforms the horizontal and vertical estimating approaches in...
متن کاملDemosaicking methods for Bayer color arrays
Digital Still Color Cameras sample the color spectrum using a monolithic array of color filters overlaid on a charge coupled device array such that each pixel samples only one color band. The resulting mosaic of color samples is processed to produce a high resolution color image such that the values of the color bands not sampled at a certain location are estimated from its neighbors. This proc...
متن کاملAn Effective Color-difference-based Demosaicking Method
This paper proposes an effective color-difference-based (ECDB) interpolation algorithm for color filter array (CFA) image demosaicking. A CFA image consists of a set of spectrally selective filters which are arranged in an interleaved pattern such that only one color component is sampled at each pixel location. To improve the quality of reconstructed fullcolor images from CFA images, the ECDB a...
