Abstract: Disclosed is a method of predicting a block vector in a multi-view image, the method including allowing an encoder to determine a reference block of a reference image for a specific block of a depth image or a specific-view image among multi-view images, allowing the encoder to determine block vector information for intra block copy (IBC) of the specific block on the basis of a block vector of the reference block when the reference block is encoded using the IBC, and allowing the encoder to encode the block vector information of the specific block. The reference image of the specific view is an image of another view, and the reference image of the depth image is a texture image corresponding to the depth image.

Abstract: There is provided a multi-view video coding artifact reduction method and system. According to an embodiment, the multi-view video coding artifact reduction method selects reference fames in neighbors of a current frame constituting a multi-view video, derives unidirectional flows and bilateral flows between the current frame and the reference frames, warps the reference frames based on the derived flows, generates intermediate frames by fusing the current frame, the reference frames, and the warped reference frames, and generates a final frame by fusing the current frame and the intermediate frames. Accordingly, image quality of the multi-view video can be more enhanced.
