Quantization (scaling) matrices for HEVC standards using an HVS-based mathematical model and data analysis are described herein. A quadratic parameter model-based quantization matrix design is also included.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A method of implementing a quantization matrix design for high efficiency video coding programmed in a memory of a device comprising:
 a. determining intra quantization matrices of square-shaped blocks; and   b. converting the intra quantization matrices of the square-shaped blocks into corresponding inter square-shaped quantization matrices.   
     
     
         2 . The method of  claim 1  further comprising determining intra quantization matrices of rectangular-shaped blocks. 
     
     
         3 . The method of  claim 2  further comprising converting the intra quantization matrices of the rectangular-shaped blocks into corresponding inter rectangular-shaped quantization matrices. 
     
     
         4 . The method of  claim 1  wherein converting comprises using reference advanced video coding quantization matrices model-based algorithms. 
     
     
         5 . The method of  claim 1  wherein the intra quantization matrices are derived from contrast sensitivity functions adjustment-based algorithms. 
     
     
         6 . The method of  claim 1  wherein the intra quantization matrices are selected from the group consisting of 4×4, 8×8, 16×16 and 32×32. 
     
     
         7 . The method of  claim 2  wherein the intra quantization matrices are selected from the group consisting of 16×4, 32×8, 8×2 and 32×2. 
     
     
         8 . The method of  claim 1  wherein the device is selected from the group consisting of a personal computer, a laptop computer, a computer workstation, a server, a mainframe computer, a handheld computer, a personal digital assistant, a cellular/mobile telephone, a smart appliance, a gaming console, a digital camera, a digital camcorder, a camera phone, an portable music player, a tablet computer, a video player, a DVD writer/player, a Blu-ray writer/player, a television and a home entertainment system. 
     
     
         9 . A method of implementing a quantization matrix design for high efficiency video coding programmed in a memory of a device comprising:
 a. determining intra quantization matrices of square-shaped blocks and the intra quantization matrices of rectangular-shaped blocks; and   b. converting the intra quantization matrices of the square-shaped blocks into corresponding inter square-shaped quantization matrices and the intra quantization matrices of the rectangular-shaped blocks into corresponding inter rectangular-shaped quantization matrices.   
     
     
         10 . The method of  claim 9  wherein converting comprises using reference advanced video coding quantization matrices model-based algorithms. 
     
     
         11 . The method of  claim 9  wherein the intra quantization matrices are derived from contrast sensitivity functions adjustment-based algorithms. 
     
     
         12 . The method of  claim 9  wherein the intra quantization matrices are selected from the group consisting of 4×4, 8×8, 16×16 and 32×32. 
     
     
         13 . The method of  claim 9  wherein the intra quantization matrices are selected from the group consisting of 16×4, 32×8, 8×2 and 32×2. 
     
     
         14 . The method of  claim 9  wherein the device is selected from the group consisting of a personal computer, a laptop computer, a computer workstation, a server, a mainframe computer, a handheld computer, a personal digital assistant, a cellular/mobile telephone, a smart appliance, a gaming console, a digital camera, a digital camcorder, a camera phone, an portable music player, a tablet computer, a video player, a DVD writer/player, a Blu-ray writer/player, a television and a home entertainment system. 
     
     
         15 . An apparatus comprising:
 a. a memory for storing an application, the application for:
 i. determining intra quantization matrices of square-shaped blocks; and 
 ii. converting the intra quantization matrices of the square-shaped blocks into corresponding inter square-shaped quantization matrices; and 
   b. a processing component coupled to the memory, the processing component configured for processing the application.   
     
     
         16 . The apparatus of  claim 15  further comprising determining intra quantization matrices of rectangular-shaped blocks.
