# CSE5519 Advances in Computer Vision (Lecture 2)
|
|
|
|
## A brief history (time) of computer vision
|
|
|
|
### Theme changes
|
|
|
|
- Prominence of computational and software concerns (was always constraining, always unevenly distributed)
|
|
- Optimization - not procedural reasoning
|
|
- Data and learning - no rules
|
|
- Rich appearance and discriptors - no simple point and line features
|
|
- Deformable template for recognition
|
|
- In the long run, data and computation win over cleverness - [bitter lesson](http://www.incompleteideas.net/IncIdeas/BitterLesson.html).
