Method for image prediction of multi-view video codec and computer readable recording medium therefor

A non-transitory computer-readable recording medium storing a program for executing a method for image prediction of a multi-view video codec, which encodes multi-view images comprising a base-view image and at least one different-view image which is captured from a different viewpoint from a viewpoint capturing the base-view image, the base-view image and the different-view image being captured at a same time, the method comprising:

• partitioning the base view image into a plurality of base blocks;
• predicting a base block among the base blocks based on the different-view image and a different-time image which is captured at a time different from a time when the base view image is captured, the base view image and the different-time image being captured from a same viewpoint;
• acquiring a difference between a prediction result of the base block and the base block, and encoding the difference;
• and
• generating a bitstream comprising the encoded difference,
• wherein the predicting the base block comprises using at least one of a first residual adjusted using a second residual and a second residual adjusted using the first residual, and
• wherein the first residual is a difference between the base-view image and the different-time image, and the second residual is a difference between the base-view image and the different-view image.

A method for image prediction of a multi-view video codec, which encodes multi-view images comprising a base-view image and at least one different-view image which is captured from a different viewpoint from a viewpoint capturing the base-view image, the base-view image and the different-view image being captured at a same time, the method comprising:

• partitioning the base-view image into a plurality of base blocks;
• predicting a base block among the base blocks based on the different-view image or a different-time image which is captured at a time different from a time when the base-view image is captured, the base-view image and the different-time image being captured from a same viewpoint;
• acquiring a difference between a prediction result of the base block and the base block, and encoding the difference;
• and
• generating a bitstream comprising the encoded difference,
• wherein in case where the base block is predicted by using the different-view image, the predicting the base block comprises performing weighted prediction by applying at least one weighting value to the base-view image and the different-view image.
