A brief history of computer vision

• Camera Obscura (16th century, AD)

  

• Hubel & Wiesel (1959)

  Inspiration of computer vision

  

  Simple cells / Complex cells / Hypercomplex cells

  

• Larry Roberts (1963)

  Block world

  The construction of a visual system

• David Marr. (1970s)

  Hierarchical model

  

  Input image

  Edge image

  2.5-D image - 2D 스케치에서 객체를 분리해내는 과정

  3-D model

• Generalized Cylinder (1970s) & Pictorial Structure (1973)

  

  cylinder → 부피감을 표현하는데 적합

  pictorial (node) → joint한 움직임을 표현하는데 적합
