K.U. K.U. & Leuven & Leuven An overview of some vision trends  scene reconstruction  recognition  tracking

K.U. K.U. & Leuven & Leuven Scene reconstruction  3D acquisition with off-the-shelf HW  4D capture: dynamic 3D  Realistic texture synthesis  City modelling  Intuitive visualisation

K.U. K.U. & Leuven & Leuven Recognition

K.U. K.U. & Leuven & Leuven Object recognition  Independent of viewpoint  Irrespective of occlusion  In the presence of scene clutter  Under variable illumination  Robust against deformations Latest techniques based on `invariant regions’

K.U. K.U. & Leuven & Leuven The ellipses show invariant regions, they cover the same part of the scene The crux is that they were found independently Object recognition

K.U. K.U. & Leuven & Leuven Object recognition  Example application: automatic annotation of video data  E.g. finding same object somewhere else in a complete movie Searching for the van in `groundhog day’

K.U. K.U. & Leuven & Leuven Automatic retrieval of all scenes with the van based on the example image

K.U. K.U. & Leuven & Leuven Object recognition  Next challenge: categorisation  i.e. not recognising particular objects, but rather the class an object belongs to, e.g. a car, a person, etc. This is more difficult, because of the Intra-class variability…

K.U. K.U. & Leuven & Leuven Object recognition  Next challenge: categorisation

K.U. K.U. & Leuven & Leuven Finding people  Security / surveillance / annotation e.g. pedestrian detector

K.U. K.U. & Leuven & Leuven Tracking  Robust blob tracking – anti-drift  Body pose tracking  Detailed hand tracking  Action recognition  Gait analysis
