Tutorial - Visual Fusion for Pattern Recognition
Time: 9:00am - 1:00pm EDT (GMT -4)
Many pattern recognition tasks, whether carried out by humans or machines are facilitated by the use of multimodal sensing (e.g. RGB, infrared, thermal, depth, hyperspectral, LIDAR) which provides complementary information about the objects or phenomena to be classified by measuring their different properties. However, this raises the problem of fusing the multiple sources of information (views). The problem has been addressed by research in image fusion. The aim of this tutorial is to provide an overview of the visual information fusion area, covering:
- (1) Problem formulation and prerequisites
- (2) Visual fusion frameworks
- (3) Image fusion techniques
The use of the fusion techniques described will be illustrated on different applications, including visual object tracking.
