1. A method comprising: obtaining a plurality image pixels from at least one image sensor, wherein the plurality of image pixels comprises: a first image of a first color, a second image of the same first color, a third image of a second color, and a fourth image of a third color; constructing a first disparity map using the plurality of image pixels by calculating pixel disparities between the first image and the second image via mono-chromatic stereo matching, the first disparity map being associated with a first direction; constructing a second disparity map, the second disparity map being associated with a second direction; warping the third image, along the second direction using the second disparity map, to create a corrected third image; warping the fourth image, along the first direction using the first disparity map and along the second direction using the second disparity map, to create a corrected fourth image; and combining the first image, the corrected third image, and the corrected fourth image to create a fused multi-channel color image.
