Abstract

Embodiments of the present invention provide multi-view video coding and coding methods and corresponding apparatuses. The multi-view video coding method includes: minimizing an error between a currently coded view image and a warped view image of a front view image to obtain an optimal warping offset; calculating disparity information between the front view image and the currently coded view image by using the optimal warping offset, a camera parameter of a view, and depth image information of the front view image; and calculating the warped view image of the front view image by using the disparity information and the front view image, and predicting a current view image by using the warped view image as a prediction signal.
