1. Working at Fuel-3D!: (2014); Starting from 11th of August 2014 I have been working at Fuel-3D, a company which currently produces one of the most accurate 3D scanners in the market in its price category. Fuel-3D is a spin-off ...; Created on 27 October 2014
2. Tutorials: (Tutorials); Here you can find tutorials and other material that I think is worth sharing with the rest. As soon as I come up with something useful I will try to include the material here.; Created on 27 April 2014
3. Representation Spaces: (2013); ... directly for vector valued images, such as RGB. It is clear that the grey value constancy assumption does not hold for surfaces with a non-Lambertian behaviour and, therefore, the underlying image representation ...; Created on 07 August 2013
4. Optical Flow in Cellular Biology: (2012); ... end growing and protrusion formation in fluorescence microscopy images. For these cases we bound OF error and optimal sampling rate, in order to guide biologists on their experimental conditions. We also ...; Created on 19 November 2012
5. Experimental Study of Image Representation Spaces in Variational Disparity Calculation: (Publications); ... directly for vector valued images, such as RGB. It is clear that the grey value constancy assumption does not hold for surfaces with a non-Lambertian behaviour and, therefore, the underlying image representation ...; Created on 16 November 2012
6. Spatial and Temporal Constraints in Variational Correspondence Methods: (Publications); ... Results In the following there are two videos, from to the DRIVSCO project, processed with the proposed method. Stereo Disparity Left- and right-images are the images received from the cameras, ...; Created on 16 November 2012
7. Disparity Disambiguation by Fusion of Signal- and Symbolic-level Information: (Publications); ... processed both with and without an external guide. Disparity is calculated with a so called phase-based method (suitable for realtime FPGA implementation). Left- and right-images are the images received ...; Created on 16 November 2012
8. Active Contour Code: (2012); I have made an example, with Matlab code included, related to both geometric- and geodesic level sets models. The example shows how the boundary separating inner- and outer parts of the segment can be ...; Created on 11 November 2012
9. Cedai: (2012); ... analysis based on Internet. Using algorithms familiar from the field of 'machine vision', movement, concentration and vitality of the spermatozoa are analysed. This way, images or videos made at any ...; Created on 23 July 2012
10. Site Constructed: (2012); ... my colleagues, related to machine vision, to anyone interested in the area. The idea is to include images, videos, program code, pdfs, and so on, in order for others to test with the techniques that we ...; Created on 10 May 2012
11. More information: (Publications); ... disparity methods typically tend to fail, possibly leading to an incorrect scene interpretation. Journal: Sent for publication Below are some of the results related to the Middlebury test images and ...; Created on 09 May 2012
12. 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 going ...; Created on 09 May 2012
13. Optical Flow: (Topics); ... seen in the following figure: The figure above shows two different images taken at times \(t\) and \(t+1\). Movement of the pixel is observed as a change in the illumination level of the pixel. As ...; Created on 09 May 2012
14. Stereo Disparity: (Topics); ... between the two images, and this is used for 3D reconstruction of a scene. The image above shows a 3D reconstruction based on stereo disparity. As it can be understood, this kind of technology can be used ...; Created on 09 May 2012
15. Research: (Research); ... of the scene. Typically the images are rectified (using epipolar geometry) meaning that point correspondences are on horizontal lines. Optical-Flow Optical-flow refers to apparent movement of pixels ...; Created on 09 May 2012
16. Jarno Ralli: (Menu); ... and segmentation of images. One interesting branch of methods for approximating both optical flow and stereo disparity maps are based on the field of mathematics known as calculus of variations. Interestingly, ...; Created on 09 May 2012
