Abstract: An image enhancement method for video analysis or automatic video surveillance systems has at least one image acquisition device, through which an IR thermal spectrum image is captured from an area of space, a scene calibration system and a detection system, through which at least one object type is detected. The method includes at least one processing stage in which the contrast of the captured image is enhanced by the image acquisition device through the image's depth or scene information obtained directly or indirectly by the scene calibration system or entered manually by the user.

Abstract: Method for converting phonemes to written text and corresponding computer system and computer program. In languages having a low correspondence between sounds and letters, converting phonemes to letters is complex. The continual addition of neologisms, with an adapted pronunciation but with an original spelling makes the conversion even harder. The conversion based solely on phonetic dictionaries requires very extensive and permanently updated dictionaries. The method for converting phonemes to written text comprises: [a] a stage of reading a finite sequence of phonemes to be converted which form a word to be converted, [b] a stage of generating a plurality of possible words, [c] a stage of choosing one of said possible words as the correct word. So the problem is broken down into two steps and the most suitable strategy can be applied to each step.
