Discrete complex exponentials are almost periodic signals, not always periodic; when periodic, the frequency determines the period, but not viceversa, the period being a chaotic function of the frequency, expressible in terms of Thomae's function. Th

Automatic video production of sports aims at producing an aesthetic broadcast of sporting events. We present a new video system able to automatically produce a smooth and pleasant broadcast of Basketball games using a single fixed 4K camera. The syst

We give an input/output characterization of the Teager-Kaiser operator, then we classify the root signals (those that remain invariant) and the pre-constant signals (those that produce a constant output) of the operator. With the gained knowledge, a

El conteo de vehículos es una tarea fundamental en los aforos de tráfico, tanto para el diseño de nuevas vías como para el control y la optimización del tráfico urbano. En ciudades como Bogotá, este conteo actualmente se realiza en forma manua

International audience; Scene flow is defined as the motion field in 3D space, and can be computed from a single view when using an RGBD sensor. We propose a new scene flow approach that exploits the local and piecewise rigidity of real world scenes.

We propose a method to compute local scene flow by tracking in intensity and depth.We propose a pixel motion model to constrain the 3D motion vector on 2D.We extend the Lucas-Kanade framework to work with intensity and depth data.Throughout some expe

The retinal blood vessels are very sensitive to the changes in the blood pressure. The changes in diameter of retinal vessels are an important sign of diseases such as hypertension, arteriosclerosis and diabetes, and may be used for the prevention of
