We use our adapted versions of the two most used methods in Computer Fluid Animation, Marker and Cell and Smoothed Particle Hydrodynamics, to develop a new method taking advantage of the calculation speed of the first and ...

In the animation process of a human-like 3D model, a skeleton must be specified to define the model’s surface deformation of its limbs. Nowadays the skeleton specification is hand made and very time consuming task. In ...

In the animation, the process of rigging a character is an elaborated and time consuming task. The rig is developed for a specific character, and it can not be reused in other meshes. In this paper we present a method ...

We complete the study of the bifurcations of saddle/spiral bimodal linear systems, depending on the respective traces T and t: one 2-codimensional bifurcation; four kinds of 1-codimensional bifurcations. We stratify the ...

Camera calibration is a critical problem in applications such as augmented reality and image based model reconstruction. When constructing a 3D model of an object from an uncalibrated video sequence, large amounts of frames ...

We continue the study of the structural stability and the bifurcations of planar continuous bimodal linear dynamical systems (that is, systems consisting of two linear dynamics acting on each side of a straight line, ...

The estimation of player positions is key for performance analysis in sport. In this paper, we focus on image-based, single-angle, player position estimation in padel. Unlike tennis, the primary camera view in professional ...
