18. Texel이란 도대체 무엇인가?
Texel ~= Low Level Feature
…
Texel Texel…?
작으면 Edge 같은거, 크면 Shape Matching
~> 작으면 Constraint가 적으니, 더 Robust할 수 있음?!
CNN == Statistical Approach + Bag of (Texton) Generator
19. Why CNN is Texture sensitive?
<CDH 생각>
Texture는 한 이미지/여러 이미지에서 고 반복, Object Shape는 한번만 나옴
== Texture는 Object 크기에 무관하지만, Shape는 Object 크기에 연관
== Shape Extractor는 하나의 이미지와만 크게 연관 있지만, Texture는 여러 이미지와 연관 있음

20. Why CNN is Texture sensitive?
Texture Kernel (Low Level)
Object Kernel (High Level)
Many Activation Middle Activation
One Activation No Activation
Maybe CNN is Texture Mapper… Not Template Matching
