摘要
This paper presents an efficient post-processing/enhancement Solution capable of reducing visual artifacts introduced during the image demosaicking process. Edge-sensing weights and the original color filter array data are used to detect structural elements in the captured image, and correct color components generated by the demosaicking process using adaptive, spectral model-based enhancement operations. The solution produces excellent results in terms of both objective and subjective image quality measures. (C) 2005 Elsevier Ltd. All rights reserved.
