Abstract: The disclosed subject matter refers to a method and device for low latency multipoint control and detection applied to, for example, a capacitive grid. The grid includes or consists of a series of conductive microfilaments, placed between two transparent plates or layers, arranged in interconnected rows and columns forming a matrix. The electromagnetic field reading enables the detection of objects which are in the vicinity of or in contact therewith. The disclosed subject matter shows high sensitivity enabling the detection of electrically-loaded air and/or vapour, more specifically the detection of intensity, direction and location of an expelled air or vapour mass, also providing a simultaneous touch detection. The disclosed subject matter is useful in boosting interaction capacities between systems and users, the invention being also possibly applied in detection/interaction systems (either simultaneous, or not).

Abstract: The present invention relates to a method, apparatus and computer program product for providing contour information related to images. An image obtaining unit obtains a set of interrelated images (step 26), an image segmenting unit segments said images, (step 28) and a contour determining unit (22) extracts at least two contours from the segmentation (step 30), selects interest points on the contours of each image (step 32), associates interest points with corresponding reconstructed points by means of three-dimensional reconstruction (step 34), projects reconstructed points into the images (step 36), and links reconstructed points not projected at a junction or their projections to each other in order to provide a first set of links (step 38), such that at least a reasonable part of a contour of an object can be determined based on the linked reconstructed points.
