【 摘 要 】

In this paper we fuzzify the bilinear colour interpolation and the non-linear colour differential correlative interpolation techniques of colour demosaicking, using the edge strength map of the mosaic image. In doing so we ensure that the edges have less participation in the interpolation thereby minimizing the interpolation error. The result is faster and more accurate colour demosaicking algorithms with application to high resolution images. The overall improvement is quite significant when it comes to colour interpolation of high definition/high resolution images containing a lot of detail or edges as proved by the extensive experimental results on state-of-the-art databases and state-of-the-art comparison.Defence Science Journal, Vol. 64, No. 1, January 2014, DOI:10.14429/dsj.64.4732
