Definitions

  • the invention relates generally to video coding.
  • Inter prediction is an important technology to improve the compression efficiency of video coding systems.
  • inter prediction can be uni-directional prediction or bi-directional prediction.
  • For one block coded by inter prediction there is only one predictor generated by integral or fractional motion compensation when uni-directional prediction is used. If bi-directional prediction is selected for this inter-predicted block, then there are two predictors generated by motion compensation and the final predictor is generated by averaging these two predictors.
  • the fractional motion compensation is implemented by one pre-defined 8-Tap interpolation filter for luma component and one pre-defined 4-tap interpolation filter for chroma component, respectively.
  • the process of inter prediction in HEVC is fixed, e.g. averaging in bi-directional prediction or filter coefficients in fractional motion compensation, so they cannot fit the characteristics of variant blocks well. Therefore, in order to further improve the compression efficiency of inter prediction, an adaptive inter prediction method is presented in the following.
  • the proposed method is to utilize the correlation between current block and neighboring reconstructed pixels to achieve the local adaptation of inter prediction.
  • Fig. 1 is a diagram illustrating an example of proposed method. Three interpolation filters can be used, and the selection is based on the distortion between neighboring reconstructed pixels and extra motion compensated pixels.
  • the proposed method is to utilize the correlation between current block and neighboring reconstructed pixels to achieve the local adaptation of inter prediction.
  • the method is named as adaptive inter prediction.
  • three kinds of interpolation filters in fractional motion compensation can be used in one video coding system. In the beginning, we perform extra motion compensation with these three interpolation filters for neighboring reconstructed pixels around current block to generate extra motion compensated pixels, as shown in Fig. 1. Next, the distortions between neighboring reconstructed pixels and extra motion compensated pixels are calculated for these three kinds of interpolation filters, and the interpolation filter with the smallest distortion is used to generate the predictor of current block.
  • adaptive inter prediction can be achieved by switching different interpolation filters.
  • adaptive inter prediction can be implemented by supporting different weighting factors between two predictors, e.g. [0.5, 0.5] , [0.25, 0.75] , [0.75, 0.25] , [0.375, 0.625] , or [0.625, 0.375] .
  • different weighting factors of two predictors, different interpolation filters can also be used in bi-directional prediction.
  • different inter prediction methods can be combined to be another inter prediction method, e.g. different weighting factors with variant interpolation filters.
  • the distortion between neighboring reconstructed pixels and extra motion compensated pixels can be sum of absolute differences, sum of square errors, and so on.
  • the distortion can be calculated with only one extra motion compensation using the following steps, where X denote the neighboring reconstructed pixels:
  • the supported adaptive inter prediction methods can be signaled at sequence level, picture level or slice level. And the supported adaptive inter prediction methods can be dependent on slice type, prediction mode, or motion information.
  • Embodiments of adaptive inter prediction according to the present invention as described above may be implemented in various hardware, software codes, or a combination of both.
  • an embodiment of the present invention can be a circuit integrated into a video compression chip or program codes integrated into video compression software to perform the processing described herein.
  • An embodiment of the present invention may also be program codes to be executed on a Digital Signal Processor (DSP) to perform the processing described herein.
  • DSP Digital Signal Processor
  • the invention may also involve a number of functions to be performed by a computer processor, a digital signal processor, a microprocessor, or field programmable gate array (FPGA) .
  • processors can be configured to perform particular tasks according to the invention, by executing machine-readable software code or firmware code that defines the particular methods embodied by the invention.
  • the software code or firmware codes may be developed in different programming languages and different format or style.
  • the software code may also be compiled for different target platform.
  • different code formats, styles and languages of software codes and other means of configuring code to perform the tasks in accordance with the invention will not depart from the spirit and scope of the invention.
