H.264/MPEG 동영상 압축 코덱의 인코더, 디코더 구현

프로젝트 목적

  • C프로그래밍을 활용하여 코덱의 전체과정 구현
  • 각 단계의 출력 영상을 확인하면서 동영상 압축과정을 이해하고 영상신호처리의 역량 향상

구현 내용

  • 8 x 8 macroblock partitioning
  • 예측 부호화
    • Intra prediction: Vertical, Horizontal, DC mode
    • Inter prediction: Spiral scan, Motion compensation
    • Pixel DPCM, DC DPCM 
  • 변환 부호화: DCT, Inverse DCT, Quantization
  • Reordering: Zigzag scan
  • 엔트로피 부호화: Huffman coding
  • 3개의 실험영상에 대해 총 144개의 case를 확인
  • 실험 과정의 효율을 높이기 위해 실험용 코드의 조건을 변경 가능한 Bat file 구현

Input Data

  • YUV 4:2:0

  • This project shows the process of image codec.
