    摘要: The present invention relates to a method of generating an image scaling curve, where local saliency is detected in a received image. The detected local saliency is then accumulated in the first direction. A final scaling curve is derived from the detected local saliency and the image is then possibly rescaled in a second direction by using the derived scaling curve, wherein the second direction is substantially orthogonal to the first direction.

    摘要: The present invention relates to a device and a method for extracting information from detected characteristic signals. A data stream (76, 78, 80, 82) derivable from electromagnetic radiation (14) emitted or reflected by an object (11) is received and a plurality of characteristic index elements (50) varying over time can be extracted therefrom. The index elements (50) comprise physiological information (48) indicative of at least one at least partially periodic vital signal (12), and a disturbing signal component (58). For eliminating the disturbing signal component (58) to a great extent, the characteristic index elements (50) can be projected to a disturbance-reduced index element (64) having a distinct orientation in relation to a presumed orientation of the disturbing signal component (58). The disturbance-reduced index element (64) is chosen so as to reflect a dominant main orientation and length of the disturbing signal component (58) over time. Consequently, the mainly genuine physiological information (48) extracted from the data stream (76, 78, 80, 82) in this way can be utilized for determining the at least one at least partially periodic vital signal (12).

    摘要: In a video processing system where motion vectors are estimated for a subset of the blocks of data forming a video frame, and motion vectors are interpolated for the remainder of the blocks of the frame, a method includes determining, for at least at least one block of the current frame for which a motion vector is not estimated (204), whether a block to the left or right has an estimated zero motion vector (206), determining whether the at least one block had an estimated zero motion vector in a previous frame (206), and if both determinations are affirmative (208), providing a predetermined motion vector for the at least one block. The predetermined motion vector may be a zero motion vector (208).

    摘要: A method and apparatus for generating an enhanced image is provided. The method includes receiving (101) an image to be enhanced. A set of sub images is generated (103) from the image where the different sub images correspond to different spatial frequency bands for the image. A pixel value variation is determined (107) in a neighborhood region of the first pixel region for at least a first pixel region of the image. An enhanced pixel region is then generated (109) for the enhanced image by combining the first pixel region and corresponding pixel regions of sub images in response to the pixel value variation. Specifically, a weighted summation of the input image and sub images may be generated with the weights being determined in response to the luminance variance in the neighborhood region. The invention may e.g. provide improved contrast enhancement with reduced artifacts and/or noise.

    摘要: The invention relates to a method for de-interlacing a hybrid video sequence using at least one estimated motion vector for interpolating pixels. Field for petition patents, typically occurring in film originated video material, disturb the function of de-interlacing algorithm designed to convert interlaced video single into progressively scanned video. Therefore a mode decision has to be applied for local adaptation to the film/video mode, which is possible by defining values for a first motion vector and a second motion vector, calculating at least one first pixel using at least one pixel of previous image and one first motion vector, calculating at least one second pixel using at least one pixel of a next image and one second motion vector, calculating a reliability of said first and the second motion vector by comparing at least said first pixel with at least said second pixel the first and said second motion vectors being pre-defined for said calculation of reliability, and estimation an actual value for a motion vector, which turned out to be most reliable for de-interlacing said image.
