Abstract: Provided are a method and an apparatus for enoding/decoding a multi-view video using LDI. Specifically, provided are a method and an apparatus for enoding/decoding a multi-view video using LDI, which uses a linear decorrelation process to improve compression efficiency. The LDI encoding method according to present invention includes: (i) generating the LDI including multiple layers by using color and depth information of each viewpoint image of the multi-view video; (ii) performing linear decorrelation in each layer of the LDI; (iii) performing data aggregation in each linearly-decorrelated layer of the LDI; and (iv) encoding the aggregated data in each layer of the LDI to generate an encoded LDI bit stream.
