MPEG and Image Processing

• Compressed Video Standards
  • Scalable Vector Graphics (SVG) Tiny 1.2 Specification
  •  ITU standards H.262, H.263, H.264, and H.264 Scalable Video Coding (SVC), Advanced Video Coding (AVC), H.265 High Efficiency Video Coding (HEVC)
  • VP9
  • ISO standards MPEG-1, MPEG-2, MPEG-4 Part 2, MPEG-4 Part 10, and MPEG-4
  • Fine Granularity Scalability (FGS) technology
• Video Compression Techniques
  • Entropy coding (context-adaptive binary arithmetic coding (CABAC) and context-adaptive variable-length coding (CAVLC))
  • Inter-frame prediction including multi-picture reference frames, variable block size motion compensation, motion vector search, motion estimation, motion compensation, etc.
  • Intra-frame prediction including neighboring edge spatial prediction, lossless macroblock coding, interlaced-scan video coding, macroblock adaptive frame field (MBAFF) coding, picture adaptive frame field coding (PAFF or picaff), etc.
  • Discrete cosine transform (DCT) and Hadamard transform
  • Quantization
