Abstract: A method for following hand movements in an image flow, includes receiving an image flow in real time, locating in each image in the received image flow a hand contour delimiting an image zone of the hand, extracting the postural characteristics from the image zone of the hand located in each image, and determining the hand movements in the image flow from the postural characteristics extracted from each image. The extraction of the postural characteristics of the hand in each image includes locating in the image zone of the hand the center of the palm of the hand by searching for a pixel of the image zone of the hand the furthest from the hand contour.

Abstract: A method for selecting images from a set of images (according to sharpness and contrast criteria), comprising pre-selecting images by a simplified sharpness and/or contrast analysis of each image in the set of images, and of selecting images by a finer analysis of the sharpness and/or contrast of each pre-selected image. This method is particularly useful to perform an identification by recognition of the iris.

Abstract: An internal combustion engine includes a combustion chamber, a crankshaft and inlet and outlet valves. The engine is operated with a method wherein a fresh air charge (rl) of the combustion chamber and the engine rpm (nmot) are considered when computing a pressure (ps) in a region lying upstream of the inlet valve. The computation is done by utilizing at least one of thermodynamic equations and flow equations at at least one discrete time point during a work cycle of the engine. Or, a pressure (ps) in the above region and the rpm (nmot) of the crankshaft are considered when computing the fresh air charge (rl) of the combustion chamber by utilizing one of thermodynamic equations and flow equations at at least one discrete time point during a work cycle of the engine.
