摘要： The present embodiments relate to a method and device. The method comprises obtaining at least one first point from at least one point of a point cloud by projecting said point of the point cloud onto a projection plane and obtaining at least one other point of the point cloud determined according to said at least one first point; determining and encoding at least one interpolation coding mode for said at least one first point based on at least one reconstructed point obtained from said at least one first point and at least one interpolation point defined by said at least one interpolation coding mode to approximate said at least one other point of the point cloud; and signaling said at least interpolation coding mode as values of image data.

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, called LDR image, and a high dynamic range, called HDR image, said method comprising the steps of: - computing (S1) a detail map, called LDR detail map, of the LDR image, said LDR detail map associating a detail level to each pixel of the LDR image, - computing (S2) a detail map, called HDR detail map, of the HDR image, said HDR detail map associating a detail level to each pixel of the HDR image, and - detecting (S3) regions of the scene where the detail level in the HDR detail map is greater than the detail level in the LDR detail map, said detected regions corresponding to cast shadow regions or highlights region of the scene.
摘要翻译：本发明涉及一种用于估计场景中投射阴影区域和高光区域的方法，所述场景由称为LDR图像的低动态范围图像和称为HDR的高动态范围表示图像，所述方法包括以下步骤： - 计算（S1）LDR图像的称为LDR细节图的细节图，所述LDR细节图将细节水平与LDR图像的每个像素相关联， - 计算（S2）a （HDR）细节图，所述HDR细节图将细节水平与HDR图像的每个像素相关联，以及 - 检测（S3）HDR细节图中的细节水平更高的场景的区域比LDR细节图中的细节等级高，所述检测到的区域对应于场景的投影区域或高光区域。
