Combined filter processing for video compression
Presented herein are combined filter(s) for video compression. In one embodiment, there is presented a method for overlap transforming a block. The method comprises filtering a portion of a horizontal edge of a block; and overlap transform filtering a vertical edge of the block after filtering the portion of the horizontal edge of the block.
1 . A method for overlap transforming a macroblock, comprising four blocks, said method comprising:
overlap transform filtering a portion of a horizontal edge of a block; and
overlap transform filtering a vertical edge of the block after filtering the portion of the horizontal edge of the block.
2 . The method of claim 1 , wherein the vertical edge is a right vertical edge of the block.
3 . The method of claim 2 , further comprising:
overlap transform filtering a left vertical edge of the block before overlap transform filtering a portion of the horizontal edge of the block.
4 . The method of claim 1 , further comprising:
overlap transform filtering a remainder of the horizontal edge after filtering the vertical edge.
5 . The method of claim 1 , wherein the horizontal edge of the block is a top horizontal edge, said method further comprising:
overlap transform filtering a portion of a bottom horizontal edge before filtering the vertical edge.
6 . The method of claim 5 , further comprising:
overlap transform filtering a remainder of the bottom horizontal edge after filtering the vertical edge.
7 . The method of claim 1 , further comprising:
deblocker transforming a portion of the horizontal edge before overlap transform filtering the vertical edge of the block.
8 . An integrated circuit for overlap transforming a macroblock, comprising four blocks, said integrated circuit comprising:
a controller; and
a memory connected to the controller, said memory storing a plurality of instructions that are executable by the processor, wherein execution of the instructions by the processor causes:
overlap transform filtering a portion of a horizontal edge of a block; and
overlap transform filtering a vertical edge of the block after filtering the portion of the horizontal edge of the block.
9 . The integrated circuit of claim 8 , wherein the vertical edge is a right vertical edge of the block.
10 . The integrated circuit of claim 9 , wherein execution of the plurality of instructions also causes:
overlap transform filtering a left vertical edge of the block before overlap transform filtering a portion of the horizontal edge of the block.
11 . The integrated circuit of claim 8 , wherein execution of the plurality of instruction also causes:
overlap transform filtering a remainder of the horizontal edge after filtering the vertical edge.
12 . The integrated circuit of claim 11 , wherein the horizontal edge of the block is a top horizontal edge, and wherein execution of the plurality of instructions also causes:
overlap transform filtering a portion of a bottom horizontal edge before filtering the vertical edge.
13 . The integrated circuit of claim 12 , wherein execution of the instructions also causes:
overlap transform filtering a remainder of the bottom horizontal edge after filtering the vertical edge.
14 . The integrated circuit of claim 8 , wherein execution of the instructions also causes:
deblocker transforming a portion of the horizontal edge before overlap transform filtering the vertical edge of the block.
