Background
•Computational
–2D approach to recognition.
•Lowe is reacting to Marr.
•Partly due to Lowe, recognition rarely involves reconstruction now.  (But also 3D models more rare).
–State of the art:
–Little recognition of 3D objects, grouping implicit.
–Speed, robustness a big concern.
–2D recognition through search.
•Psychology
–Much more ambitious and specific than any prior theory of recognition (I believe).
–P.O. widely studied, rarely related to other tasks.
•Contrast.
–CS must account for low-level processing.
–Psych must account for categorization.
