Transform of flow information from pixels to physical measures (motion in Km) Compute the height of each point using infrared temperature intensity value. Compute a segmentation of the infrared temperature channel Implementation of a 3D visualization tool for the layers Tracking regions using a motion model A robust tracking method could deal with layer occlusions.

12. December 2005FLUID Specific Targeted Research Project - Las Palmas Meeting12 Project risk analysis We need to design tractable applied physical models. The interplay between 2D image measurements and 3D dynamical system is perhaps too complex. We need to design a multi-layer coupling model (too complex). Computer vision groups of the project need to strongly interact with the other partners. We need to define clearly a way to share results and a validation strategy. We need to identify specific tasks in the project where different partners work together. We need to convince Bruxelles people that everything is fine.
