Title: Motion vector predictive encoding method, motion vector predictive decoding method, moving picture encoding apparatus, moving picture decoding apparatus, and programs thereof
Inventor: KITAHARA MASAKI
IPC: H04N7/32
Filed: 2011-02-08
Abstract: In order to increase the efficiency of motion vector prediction and increase the efficiency of video coding in the predictive coding of motion vectors, a motion search is performed using a coded reference image for a block to be coded in an image to be coded, and a motion vector is calculated. A plurality of blocks, which are in a predetermined position relative to the position of the block to be coded in the image to be coded and comprise at least either a coded block within the image to be coded or a coded block in a coded image, are set as the primary block candidates, and N primary reference motion vector candidates are determined from the motion vectors used in coding the primary block candidates. The reliability of the primary reference motion vector candidates, which quantitatively represents the effectiveness thereof in predicting the motion vector of the block to be coded, is calculated for each of the primary reference motion vector candidates by using coded image information. Primary reference motion vector candidates having a higher reliability than a prescribed threshold value are selected from among the N primary reference motion vector candidates as secondary reference motion vector candidates. The predicted motion vector of the block to be coded is calculated using the secondary reference motion vector candidates, and the residual between the predicted motion vector and the motion vector obtained from the motion search of the block to be coded is coded as the motion vector coding information.
