| Abstract |
Color filter array (CFA) image warping before color reconstruction is a computationally efficient image warping method. However, quality of the warped full-color image is a little bit degraded compared with the conventional full-colour image warping. In this paper, a new color image warping is proposed by unifying CFA demosaicking and image warping. The proposed method can be regarded as a generalized image warping from a CFA image to a full-color image in one step. In the proposed method, resultant image quality is almost equal to the full color image warping without significant increase of computational load. The proposed method is applied to lens distortion correction, and results are compared with the RGB full-color image warping and CFA image warping to prove validity of the proposed method. |
