摘要： Described herein is a method for correcting defective depth values in depth map images. Defective values correspond to “noisy pixels” located on continuous flat surfaces and interpolated “flying pixels” located along an edge between a foreground object and a background object. The method comprising the steps of accessing a depth map of a scene which includes the foreground and background objects, detecting and identifying noisy and interpolated depth measurements within the depth map using a method, defining and applying a correction to each of the detected defective noisy and interpolated depth measurements using a specifically defined weighted correction factor. By providing the corrected defective depth values in depth map images, edges are sharpened in depth and continuous surfaces are flattened, enabling higher efficiency and robustness of further image processing.

摘要： The present invention relates to a method for stabilizing a series of measurements of a physical variable captured by a digital sensor. This method comprises the steps of: capturing at least a first measurement, a second measurement, and a third measurement of said physical variable and storing each measurement in a digital memory. The first and second measurements are compared and, if a difference between the first measurement and the second measurement is below a predetermined threshold, the second measurement is replaced in the memory by a corrected second measurement where the difference with respect to said first measurement has been reduced using a first filtering strength. The corrected second measurement and the third measurement are compared and, if a difference between the filtered value of the corrected second measurement and said third measurement is also below the threshold, said the third measurement is replaced by a corrected third measurement where a difference with respect to said corrected second measurement has been reduced using a second filtering strength that is lower than the first filtering strength. This method has the advantage of filtering noise while still allowing slow but relevant variations in the series of measurements.

摘要： The present invention provides a method and system for determining and providing color metadata for a downlink data channel. In accordance with the present invention color metadata is determined such that gamut mapping is defined by a transmitted source gamut which enables adapted mapping that preserves saturation and contrast levels of the source for a downlink data channel. The metadata is then provided to a downlink data channel for color management.

摘要： Each color image is decomposed into at least one series of at least three successive primary images of different primary colors which are successively displayed by modulating the activation duration of the pixels of an imaging device. According to the invention, the distribution of the pixel activation phases in the three successive subframes is contracted: the pixel activation periods of the first primary image are shifted toward the end of the subframe of this first image, and, during the subframe of the third primary image, the pixel activation periods of this third primary image are shifted toward the beginning of the subframe of this third image. Color break-up faults are thus advantageously reduced.

摘要： A method for characterizing a color reproduction device. A first output color measure responding to a first reference input color value is measured under normal measurement conditions. The measurement conditions are modified and a second output color measure responding to the first reference input color value is measured under the modified measurement conditions. A transformation rule, enabling transformation between the second output color measure and the first output color measure, is calculated from the first color value and the second color value. A first set of output color measures responding to a set of input color values is measured under modified measurement conditions, and the first set of output color measures is converted, using the transformation rule, to a second set of output color measures. A system and a control device are also provided.

摘要： The invention relates to a sequential illumination system for a visual display unit comprising a light source emitting a polychromatic light beam towards said visual display unit within a wavelength range comprising at least three primary colours, and a colour wheel provided with at least three transmissive or reflective segments for transmitting said light beam along an optical path in such a way they successively cut the direction of propagation of said beam. The colour segments are distributed on the said wheel in such an order that the differences of energies perceived by the visual organ of a standard observer (visual stimuli), are as equivalent as possible during the intersegment transitions, when the segments pass along the optical path of the beam. Said invention can be used for movie projection and overhead projection devices.

摘要： Described herein is a method for recognizing a human head in a source image. The method comprises detecting a contour of at least part of a human body in the source image, calculating a depth of the human body in the source image. From the source image, a major radius size and a minor radius size of an ellipse corresponding to a human head at the depth is calculated, and, for at least several of a set of pixels of the detected contour, generating in an accumulator array at least one segment of an ellipse centered on the position of the contour pixel and having the major and minor radius sizes. Positions of local intensity maxima in the accumulator array are selected as corresponding to positions of the human head candidates in the source image.
