+
+## 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).
