ActiveCN106296748AImprove light and shadow effectsGood coloring effectImage analysis3D-image renderingTransfer modelColor transformation
The invention provides an object image relighting method based on block-matching transformation and color transfer. A block-matching algorithm and a color transformation algorithm are combined with local and global lighting transfer models; on the premise of keeping the lighting condition of a reference image constant, the color of the reference image is changed by the color transformation algorithm, so that the color of the reference image is consistent with the color of an input image; and since colors have relatively great influences on image lighting transfer, the influences of the colors on later lighting transfer processing can be lowered greatly in the above way. After the influences of color factors on results are lowered greatly, the reference image is deformed by the block-matching algorithm, so that the shape of the reference image is matched with an object in the input image. Finally, the input image and the transformed reference image are subjected to lighting transfer through local and global affine transformation, so that relighting of the input image is finished. The method is very easy to implement through software, and can be popularized and applied to a wide variety of fields such as computer vision, visual design, digital entertainment and film producing.
