Abstract:
A method, apparatus and a surround view camera system. The method includes extracting block samples from at least one of a composite view geometric LUT, input fish-eye image and view overlapping region, selecting sample inliers from the extracted block samples, estimating optimal color gain for the selected block samples, performing refined adjustment based on the estimated color gain and applying color transform, and producing a composite surround view image.
