  • Method and apparatus for tracking a number of objects or object parts in image sequences
    The present invention provides for a method for tracking a number of objects or object parts in image sequences, comprising following a Bayesian-like approach to object tracking, computing, at each time a new image is available, a probability distribution over all possible target configurations for that time, said Bayesian-like approach to object tracking comprising the following steps: - Prediction step: a probability distribution is computed for the previous image, at time (t-1), is propagated to the new image at time (t) according to a probabilistic model of target dynamics, obtaining a predicted distribution at time (t) ; - Update step: the predicted distribution at time (t) is then aligned with the evidence contained in the new image at time (t) according to a probabilistic model of visual likelihood.

  • Method for efficient target detection from images robust to occlusion
    The method for efficient target detection from images robust to occlusion disclosed by the present invention detects the presence and spatial location of a number of objects in images. It consists in (i) an off-line method to compile an intermediate representation of detection probability maps that are then used by (ii) an on-line method to construct a detection probability map suitable for detecting and localizing objects in a set of input images efficiently. The method explicitly handles occlusions among the objects to be detected and localized, and objects whose shape and configuration is provided externally, for example from an object tracker. The method according to the present invention can be applied to a variety of objects and applications by customizing the method’s input functions, namely the object representation, the geometric object model, its image projection method, and the feature matching function.

  • Self-adaptive matrix completion for heart rate estimation from face videos under realistic conditions
    Recent studies in computer vision have shown that, while practically invisible to a human observer, skin color changes due to blood flow can be captured on face videos and, surprisingly, be used to estimate the heart rate (HR). While considerable progress has been made in the last few years, still many issues remain open. In particular, state-of-the-art approaches are not robust enough to operate in natural conditions (e.g. in case of spontaneous movements, facial expressions, or illumination changes). Opposite to previous approaches that estimate the HR by processing all the skin pixels inside a fixed region of interest, we introduce a strategy to dynamically select face regions useful for robust HR estimation. The present approach, inspired by recent advances on matrix completion theory, allows us to predict the HR while simultaneously discover the best regions of the face to be used for estimation. Thorough experimental evaluation conducted on public benchmarks suggests that the proposed approach significantly outperforms state-of-the-art HR estimation methods in naturalistic conditions.

  • Laser fusion system and method
    The invention describes a system, a method and a target for producing nuclear fusion reactions. A laser is used to irradiate a single temporally shaped laser pulse comprising a pre-pulse and a main pulse or at least two consecutive laser pulses onto the target. A first of the plurality of consecutive laser pulses or a prepulse of the single laser pulse is used to generate a first plasma in front of the target. The system is configured such that this first plasma is capable to focus the second laser pulse or main iaser pulse onto the target, i.e. to reduce the focal spot size compared to the first or pre-pulse. The plasma initiates a so-called selffocusing of the second or main laser pulse onto the target. The focused second or main laser pulse can then be used to accelerate first particles such that these accelerated first particles produce nuclear fusion reactions with second particles contained in the target.
