Image Processing < signal processing

geometric transform
enhancement 화질 개선
restoration 복원
compression 데이터 압축
object recognition 객체 인식


memset()

chromaticity 색도 = 색상 + 채도

contrast = (I_max - I_min) / (I_max + I_min)

인간의 지각 작용이 단순한 명도보다 명도의 대비에 더 민감하다.

Color Models:
RGB - additive system
CMY(K) - subtractive system
HSI
YCrCb - JPEG, MPEG
YIQ - NTSC
YUV - PAL

signal - analog & digital

digitalizing:
sampling
quantization
coding step 부호화

Picture Element = Pixel = Pel

Resolution - Spatial & Intensity(Brightness)

표본화(sampling)와 양자화(quantization)로 결정하는 해상도(resolution)는 컬러 요소 세 개의 명도값(intensity)에 따라 달라진다.

Binary Image - 지문, 팩스, 문자 영상
Gray-Level Image - 디지털 영상 처리의 기본
Color Image - 삼원색(RGB)



Q1. calloc이 malloc과 어떻게 다른 거야?
