Robust semi-automated path extraction for visualising stenosis of the coronary arteries [PDF]
, 2008 Computed tomography angiography (CTA) is useful for diagnosing and planning treatment of heart disease. However, contrast agent in surrounding structures (such as the aorta and left ventricle) makes 3-D visualisation of the coronary arteries difficult ...

EDGE PRESERVING FILTERS USING GEODESIC DISTANCES ON WEIGHTED ORTHOGONAL DOMAINS [PDF]
, 2008 We introduce a framework for image enhancement, which smooths images while preserving edge information. Domain (spatial) and range (feature) information are combined in one single measure in a principled way.

PATH PLANNING OF TRACTOR-TRAILER ROBOT BY FAST MARCHING METHODE (FMM) [PDF]
مجله مدل سازی در مهندسی, 2013 This paper deals with motion planning of Tractor-trailer robots, which are car-like robot dragging several trailers with no driving force. Each trailer has a nonholonomic kinematic constraint which increases the complexity of the path planning problem ...

Sub-Riemannian Fast Marching in SE(2)
, 2015 We propose a Fast Marching based implementation for computing sub-Riemanninan (SR) geodesics in the roto-translation group SE(2), with a metric depending on a cost induced by the image data.

UAVs Formation Approach Using Fast Marching Square Methods [PDF]
IEEE Aerospace and Electronic Systems Magazine, 2020 This article presents a novel method for the management of UAVs formations. Based on the fast marching square (FM2) technique, the proposed method allows the generation of soft realizable paths for a formation in leader-followers configuration, keeping a desired geometry among its different agents.
