摘要： A method for selectively adjusting the amount of specular reflections appearing in the final image output by an image capturing device by blending two substantially perfectly overlapping images, one with natural specular reflections and one without specular reflections. In the combined image, the amount of specular reflection is lower than in the image having natural specular reflections, to the extent in many cases that the underlying image content can be seen. In any event, the apparatus provides means for selectively adjusting the intensity of specular reflection, or even eliminating it altogether, in each region of the image containing such reflection.

摘要： A video stabilization scheme which uses a dynamic programming algorithm in order to determine a best path through a notional stabilization band defined in terms of a trajectory of an image capture element. The best path is used in order to produce an optimally stabilized video sequence within the bounds defined by the image capture area of the image capture element.

摘要： The present invention relates to a system for de-warping images of a developable surface, including developable curled surfaces, and in particular of images of curled documents (30). The system (1) includes a processor (25) linked to an image capture means (2) which: captures an image of the surface (30), said image having a warp corresponding to the non-planar surface; generates from the image a first set of points representing the three-dimensional profile of the non-planar surface relative (30) to a planar reference surface (12); fits to the first set of points a second set of points representative of a developable mesh; and uses the second set of points to texture-map the image (12) in order to de-warp the image.

摘要： Automatic calibration of an eye tracking system involves capturing a plurality of eye measurements, wherein each eye measurement relates to a corresponding eye gaze position of a human eye; determining a set of statistics data from the plurality of eye gaze measurements; comparing the set of statistics of eye gaze measurements with a set of statistics relating to a plurality of pre-measured eye gaze positions of at least one person; and as a result of the comparison, determining a calibration correction factor which, when applied to the statistics of eye gaze measurements, gives an optimum match between the statistics of eye gaze measurements and the statistics of predetermined eye gaze positions.

摘要： An attention detection system comprises a portable attention detection module for receiving attention clues of a host person. The attention clues are generated from a self perspective of the host. Attention clues of the host person generated from an observer perspective are received. A sensor device generates signals relating to the attention clue signals of the self perspective. At least one sensor generates signals relating to the attention clue signals of the observer perspective. The attention detection module determines a situation of raised attention of the host wearer from the self perspective attention clues and the received observer perspective attention clues.
