    • This invention relates to a method and an apparatus for decoding a free viewpoint image, particularly for decoding a depth image by using a video image. The invention is characterized by including the steps of: receiving a video signal that includes both a video image and a depth image; acquiring the prediction direction information of a current macro-block which is an intra-block within the depth image from a corresponding block within the video image; acquiring prediction depth information of the current macro-block from neighboring blocks based on the prediction direction information of the current macro-block; and restoring the depth information of the current macro-block by using the prediction depth information. The corresponding block type is an intra-block, and the viewpoint, time and position of the corresponding block are same as those of the current block within the depth image. According to the invention, compression efficiency can be increased by removing the overlapped information from a free viewpoint image including both a video image and a depth image caused by the similarity between the video image and the depth image.
    • 本发明涉及一种用于对自由视点图像进行解码的方法和装置,特别是用于通过使用视频图像解码深度图像。 本发明的特征在于包括以下步骤:接收包括视频图像和深度图像的视频信号; 从视频图像内的相应块获取作为深度图像内的块内的当前宏块的预测方向信息; 基于当前宏块的预测方向信息,从相邻块获取当前宏块的预测深度信息; 以及通过使用预测深度信息来恢复当前宏块的深度信息。 相应的块类型是块内块,并且相应块的视点,时间和位置与深度图像内的当前块相同。 根据本发明,通过从包括视频图像和深度图像之间的相似性引起的视频图像和深度图像的自由视点图像中去除重叠信息,可以提高压缩效率。
