Method and device for estimating cast shadow regions and / or highlight regions of images

摘要

The present invention relates to a method for estimating cast shadow regions and highlight regions in a scene, said scene being represented by a low dynamic range image, referred to as an LDR image, and a high dynamic range image, referred to as an HDR image, The method includes: computing (S1) a detailed map called an LDR detailed map of LDR images, the LDR detailed map associating a detailed level with each pixel of the LDR image; Computing a detailed map, referred to as an HDR detail map of the HDR image, wherein the HDR detail map associates a detail level with each pixel of the HDR image; and - And detecting (S3) zones of the scene that are greater than the level of detail of the map, wherein the detected zones correspond to cast shadow zones or highlight zones of the scene.
