The Image Foresting Transform: Recent
Advances and Perspectives.
The most recent talk about the IFT with pointers to the key works
in the past 10 years and applications involving object tracking, image
segmentation (interative and automatic --- segmentation based on cloud
bank model) and patter recognition systems in biometry, remote
sensing, and biomedical data analysis. This lecture was presented at
the 16th International Conference on Digital Signal Processing in
2009. The following videos were presented during the talk.
The Image Foresting Transform from the Image
Domain to the Feature Space.
This lecture reviews previous works on the IFT and presents its
extension from the image domain to the feature space, where
optimum-path forest classifiers can be projected. This talk was
presented at the 8th International Symposium on Mathematical Morphology in
2007, at ESIEE in 2008 and at the University of Minnesota in 2008.
Image Foresting Transform: A Graph-Based
Approach to Image Processing.
First lecture that introduces the Image Foresting Transform (IFT) and
presents its use in the design of image processing operators. This
talk was presented at the University of Iowa and University of
Pennsylvania in 2004.
