1. Low-cost Sensor to Detect Overtaking Based on Optical-Flow: (Publications); ... and Applications As the name implies, the system detects detects overtaking vehicles based on optical-flow. Robustness of the system has been tested using more than 15,000 frames under realistic illumination ...; Created on 16 November 2012
2. Non-linear Image Diffusion and Efficient Solver: (Tutorials); ... (TDMA). The tutorial shows all the steps how the diffusion equation is discretized and how the solver is constructed. What is interesting is that this same solver can be used for solving variational optical-flow ...; Created on 27 April 2014
3. Spatial and Temporal Constraints in Variational Correspondence Methods: (Publications); ... background segmentation based upon the disparity, and/or optical-flow become easier for higher level vision stages. Furthermore, we propose a more general mechanism in which the constraints can be provided ...; Created on 16 November 2012
