Herrera Caro, Pedro Javier ; Pajares Martinsanz, Gonzalo ; Guijarro Mata-García, María ; Ruz Ortíz, José Jaime ; Cruz García, Jesús Manuel de la | SPRINGER-VERLAG BERLIN | 2009This paper describes a novel stereovision matching approach based on omni-directional images obtained with fish-eye lenses in forest environments. The goal is to obtain a disparity map as a previous step for determining the volume of wood in the[...]texto impreso
Cruz García, Jesús Manuel de la ; Herrera Caro, Pedro Javier ; Pajares Martinsanz, Gonzalo ; Guijarro Mata-García, María ; Ruz Ortíz, José Jaime | SPRINGER-VERLAG BERLIN | 2009This paper describes a novel stereovision matching approach by combining several attributes at the pixel level for omni-directional images obtained with fish-eye lenses in forest environments. The goal is to obtain a disparity map as a previous [...]texto impreso
Ruz Ortíz, José Jaime ; Arévalo, Orlando ; Pajares Martinsanz, Gonzalo ; Cruz García, Jesús Manuel de la | IEEE | 2007This paper presents an approach to trajectory generation for Unmanned Aerial Vehicles (UAV)) by using Mixed Integer Linear Programming (MILP) and a modification of the A* algorithm to optimize paths in dynamic environments, particularly having p[...]texto impreso
Fuzzy multi-criteria decision making in stereovision matching for fish-eye lenses in forest analysis

Cruz García, Jesús Manuel de la ; Pajares Martinsanz, Gonzalo ; Ruz Ortíz, José Jaime | Springer | 2009-06This paper proposes an automatic method based on the deterministic simulated annealing (DSA) approach for solving the image change detection problem between two images where one of them is the reference image. Each pixel in the reference image i[...]texto impreso
Pajares Martinsanz, Gonzalo ; Ruz Ortíz, José Jaime ; Cruz García, Jesús Manuel de la | SPRINGER-VERLAG BERLIN | 2005Under illumination variations image change detection becomes a difficult task. Some existing image change detection methods try to compensate this effect. It is assumed that an image can be expressed in terms of its illumination and reflectance [...]texto impreso

Pajares Martinsanz, Gonzalo ; Ruz Ortíz, José Jaime ; Lanillos Pradas, Pablo ; Guijarro Mata-García, María ; Cruz García, Jesús Manuel de la ; Santos Peñas, Matilde | Comite Espanol Automática CEA-IFAC | 2008-01The trajectory generation and its replanning in hostile environments for UAVs (Unmanned Aerial Vehicles) is a discipline in expansion. The hostile environments contains threats, modelled here as radars. Initially a route is planned. Then, if dur[...]texto impreso
Ruz Ortíz, José Jaime ; Arévalo, Orlando ; Cruz García, Jesús Manuel de la ; Pajares Martinsanz, Gonzalo | IEEE | 2006This paper presents an approach to trajectories optimization for Unmanned Aerial Vehicle (UAV) in presence of obstacles, waypoints, and threat zones such as radar detection regions, using Mixed Integer Linear Programming (MILP). The main result [...]
