시간축의 화상 신호를 몇 개의 신호 전력이 큰 주파수 영역과 작은 영역으로 분해하여 변환 DCT IP DCT Coefficient -217.xx -32.xx 15.xx 16.xx -1.xx 21.xx -7.xx 2.xx 5.xx -3.xx 3.xx 7.xx 10.xx -8.xx -13.xx -6.xx 6.Xx 13.xx -0.xx 3.Xx 23.xx 24.xx -19.xx -10.xx -5.xx 9.Xx 12.xx 4.xx 6.xx 20.xx 30.xx -12.xx 14.xx -9.xx -27.xx 27.xx -4.xx 14.Xx -29.xx -18.xx -24.xx 11.Xx -2.xx 1.xx -16.xx Project Goal..! Milestone Role Division Achievement Result Problem & Solution Q/A DCT input data DCT output data DCT에서는 시간축의 화상 신호를 몇 개의 신호 전력이 큰 주파수 영역과 작은 영역으로 분해하여 변환 화상 신호의 전력은 저 주파수 영역에 집중되어 있기 때문

11 Quantized Coefficient
Quantization IP Quantization IP DCT 계수 값 등을 임의의 상수로 나누어 유효자리 비트 수를 줄이는 과정 상수 값이 클수록 압축률은 높아지고 손실이 커져 화질 저하 (손실압축) 양자화 테이블 값으로 나누어 준다. (DCT / Q table) Quantized Coefficient -27 -5 2 4 1 -1 Project Goal..! Milestone Role Division Achievement Result Problem & Solution Q/A 입력 신호를 유한한 개수의 값으로 근사화하는 것. 비선형 연산이며, 원신호의 완전한 재생이 불가능하다. 입력 신호에 따라 스칼라 양자화와 벡터 양자화로 나눌 수 있으며, 부호어의 배치에 따라 균일 양자화와 비균일 양자화로 나눌 수 있다. 양자화된 결과는 디지털값으로 전송된다.

12 Achievement Result Zigzag Scan, RLE IP Zigzag Scan, RLE IP
Zig-zag을 거친 DC 요소(저주파수)는 DPCM( differential plus code modulation )을 수행. Zig-zig을 거친 AC 요소(고주파수)는 Zero RLE( Zero run length encoding )을 수행 Zigzag Scan, RLE IP Project Goal..! Milestone Role Division Achievement Result Problem & Solution Q/A Zigzag Scan Result -27 -5 2 1 -1 4 … Zigzag Scan  DPCM은 예측한 값과 실제의 값과의 차이를 부호화하므로 원래의 영상값은 0에서 255사이의 값을 가지지만, DPCM한 후에는 -255에서 255로 범위가 배로 넓어진다 중국집에서...짬뽕, 짬뽕, 짬뽕 이라고 말하지 않고... 짬뽕 셋이요~ 라고 말하는 원리가...바로...RLC...Run-Length Coding입니다...
