image processing - content analysis -> image & video understanding, motion understanding
machine learning -> visual recognition -> vision perception
 

Computer vision is to infer different factors such as camera model, lighting, color, texture, shape and motion that affect images and videos, from visual inputs.

radiometry

SfM = Structure from Motion

IBR = Image-based modeling and rendering

dynamic range

CCD = Charged-coupled device = 전하 결합 소자 (電荷結合素子)

CMOS = Complementary metal–oxide–semiconductor = 상보성 금속 산화막 반도체 (相補性金屬酸化膜半導體)


> Low-level Image Processing - edge detection, corner detection, filtering, morphology, etc.
> Low-level Vision - image matching, optical flow computation, motion analysis
> Middle-level Vision - (1) multi-view geometry, stereo, Structure from motion -> geometric modeling -> 3D reconstruction, image-based rendering (2) image segmentation -> visual tracking, visual motion capturing
> High-level Vision - (model-based / learning-based) object recognition -> image understanding, video understanding + intelligent human-computer interaction, intelligent robots, smart environment, content-based multimedia
