Definitions

  • the invention relates generally to Three-Dimensional (3D) video processing.
  • the presented invention relates to the improvement on the DC prediction method in DMM coding scheme.
  • DMM prediction is conducted differently in different cases [2]. Several judgments are involved to determine the specific case. As depicted in Fig.l, DMM prediction cases are described as follows.
  • bPatternx Y represents which segment the sample at (X,Y) belongs to.
  • bPatteriix is equal to 0 if the sample at (X,Y) belongs to segment 0 and bPatternx y is equal to 1 if the sample at (X,Y) belongs to segment 1.
  • Fig. 1 is a diagram illustrating DMM prediction cases in HTM
  • Fig. 2 is a diagram illustrating neighboring samples in the proposed method
  • Fig. 3 is a diagram illustrating neighboring samples with labels.
  • case 1 and case 2 in HTM are unified to case in the proposed method.
  • Case2' and Case 3' equal to Case3 and Case 4 in HTM, respectively.
  • (X+Y)»l are used to replace (S+T)»l in Casel or 128 in Case2 in the current HTM.
  • 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).
