Improving Correlation-Based DEMs by Image Warping and Facade Correlation
We present in this article a system which improves a DEM. The method reconstructs all the facades of the building and then, corrects the initial DEM by deleting the points of the ...

Recognizing Upper Face Action Units for Facial Expression Analysis
We develop an automatic system to analyze subtle changes in upper face expressions based on both permanent facial features (brows, eyes, mouth)andtransient facial features (deepen...
