Boosted Spatio-Temporal Features for Sign Language Recognition
We have been investigating the use of Spatio-Temporal Features to accuarately describe the motion of sign, using boosting to combine the most effective features into a single strong classifier per sign.
A brief look at this system is given over the following pages:
The Integral Volume - An introduction to the basis of our method.
Spatio-Temporal Features - The features that make use of the Integral Volume.
Image Buffer - Our solution to numerical precision over long video streams.
Learning - Some thoughts on Boosting algorithms and their suitability for this problem.
Results - Results of experimentation
