In view of the effect of the distributing direction of an image texture on the precision of the fractional pixel reference samples, the inter-frame predicting encoding/decoding technology according to the present invention performs a fractional pixel interpolation on the integer pixel samples of an image block to be encoded many times to obtain a plurality of groups of the fractional pixel reference samples with different precision, then selects the reference samples with the highest precision from the integer pixel samples and each group of the fractional pixel reference samples, so the encoding rate of the encoding side is increased. The fractional pixel interpolation technology according to the present invention sets up at least two different interpolation directions and calculates the corresponding predicting values, then selects the best value from all of the predicting values as the best predicting value of the fractional pixel samples to be interpolate, so the precision of the fractional pixel samples is increased.

摘要： A method and an apparatus of multi-view coding and decoding are disclosed herein. In the process of encoding multi-view video images, the frame number and the view identifier information of the image that uses auxiliary reference information are written into a code stream, and sent to the decoder. Therefore, through decoding, the decoder can obtain the frame number and the view identifier information of the image that uses the auxiliary reference information, and determine the auxiliary reference information applied to the specified image according to the frame number and the view identifier information. Further, errors of the image may be concealed according to the auxiliary reference information. Therefore, the inter-frame information effectively usable to the process of concealing errors may be determined at the decoder according to the view identifier information, thus improving the performance of multi-view video coding and decoding.
