摘要： A method of obtaining a disparity vector and its encoding/decoding in the multi-view coding process is disclosed. The present invention includes essentially: determining a disparity vector between two views during the multi-view image coding, and computing a disparity vector between the other two views according to the disparity vector between the two views and the known relative location information between each of the views. Thereafter, the disparity vector is used for multi-view encoding/decoding. The present invention further makes use of the correlation between the disparity vector and depth information of the spatial vector on one hand, and on the other hand makes use of the direct relationship between the disparity vector and the location of each of the cameras. It is experimentally proved that the disparity vector between several views can be accurately computed during the multi-view coding, thereby improving the performance of multi-view coding.

摘要： An image interpolation method includes: obtaining pixel values of integer pixel points and/or sub-pixel points in the row, column or any other directions of pixel points; obtaining pre-calculated interpolation coefficients, and interpolating the pixel points. A method for obtaining image interpolation coefficients includes: solving a one-dimensional Wiener-Hopf equation to obtain needed interpolation coefficients in different directions. An image interpolation apparatus performs interpolation filter processing on pixel points by using a first obtaining module, a second obtaining module, and a first calculating module.
