COLOUR IMAGE ENHANCEMENT GUIDED BY A GREYSCALE IMAGE |
摘要 |
A camera device includes monochromatic and color image sensors that capture an image as a clear image in monochrome and as a Bayer image. The camera device implements image processing algorithms to produce an enhanced, high-resolution HDR color image. The Bayer image is demosaiced to generate an initial color image, and a disparity map is generated to establish correspondence between pixels of the initial color image and clear image. A mapped color image is generated to map the initial color image onto the clear image. A denoised clear image is applied as a guide image of a guided filter that fillers the mapped color image to generate a filtered color image. The filtered color image and the denoised clear image are then fused to produce an enhanced, high-resolution HDR color image, and the disparity map and the mapped color image are updated based on the enhanced, high-resolution HDR color image. |
