1. Matlab Code for Stereo Disparity Segmentation: (2014); Here it is finally, the segmentation code that I had promised quite long time ago! The Matlab code segments stereo disparity maps using a model based on implicit dynamic surfaces (also known as level sets). ...; Created on 07 May 2014
2. Representation Spaces: (2013); Abstract: Correspondence techniques start from the assumption, based on the Lambertian reflection model, that the apparent brightness of a surface is independent of the observer's angle of view. Fro ...; Created on 07 August 2013
3. Experimental Study of Image Representation Spaces in Variational Disparity Calculation: (Publications); Abstract Correspondence techniques start from the assumption, based on the Lambertian reflection model, that the apparent brightness of a surface is independent of the observer's angle of view. From this ...; Created on 16 November 2012

12. Optical Flow Code: (Code samples); One complete chapter of my thesis is devoted to explaining how the variational optical flow, disparity and level-set models can be solved. In this chapter I show, step by step, how these models can be ...; Created on 09 May 2012
13. Stereo Disparity Code: (Code samples); Variational methods for approximating disparity and optical flow are quite similar. Basically the same model that can be used for approximating optical flow with big displacements (late linearisation with ...; Created on 09 May 2012
14. More information: (Publications); ... Our model can detect an approaching vehicle (multiple-lane overtaking scenarios) and warn the driver about the risk of changing lanes. Thanks to the use of tightly coupled analog and digital processors ...; Created on 09 May 2012
15. Segmentation: (Topics); Level-set Based Segmentation in 2D Before introducing the actual model used for segmenting 2D images, few things related to explicit and implicit curve representations are discussed. Before ...; Created on 09 May 2012
