摘要

An efficient edge-based technique for color filter array demosaicking is presented in this paper. The proposed algorithm uses the channel information from several correlated neighboring pixels to reconstruct the missing color channels of each pixel. We employ a simple edge detector to recognize the edge direction of each processing channel by using directional color differences, and an efficient color interpolator to reconstruct the missing color channels by observing the color correlation and edge information. The proposed technique can prevent image blur and demosaicking artefacts; moreover, it has a fixed local window size and requires no previous training and no iterations. Extensive experimental results demonstrate that the proposed technique preserves edge features and performs effectively in quantitative evaluations and visual quality. The proposed algorithm has a simple computation structure; therefore, it is appropriate for real-time hardware implementation and can be used in many real-time applications.
