A novel approach for bit-depth expansion is proposed. When displaying a low bit-depth image on a monitor, false contour artifacts tend to appear in the gradation region. Such false contours seriously degrade the image quality. Reconstructing smooth gradations from false contours is crucial yet it remains difficult problem for 2D images. The proposed method enables the 2D interpolation problem to be separated into a 1D problem. An output image with smooth gradations can be obtained by using the Poisson equation. |
