    摘要: A method and apparatus for thinning lines in a video, includes providing a line signal (15) of a video, the line signal (15) having pair of spaced apart transitions (16) which slope toward one another and merge at an edge (17) of a first thickness, the first thickness of the edge generating a line of a given width in the video. At least one of the transitions (16) is moved toward a center of the edge (17), to produce a new line signal (18) having an edge (19) of a second thickness which is less than the first thickness, thereby reducing the given width of the line in the video.

    摘要: A system and method for distributing candidate motion vectors divides a picture frame (110) into a plurality of segments (120), where each segment (120) includes a plurality of pixel blocks (130). The local motion complexity of each segment may then be measured by determining a Sum-of-Absolute Differences (SAD) between pixel blocks (130) of the frame (110a) and pixel blocks (130)of an adacent frame (110b) and summing the SAD values for the pixel blocks (130) within each segment (120). The maximum, minimum and average SAD value for the segments may be used to define a distribution function that distributes candidate vectors to conform with a desired maximum, minimum and average number of candidate vectors per block. This distribution function is then used to determine the number of candidate vectors to assign to pixel blocks (130) based on the measured SAD value of the associated segment (120).

    摘要: An apparatus to provide a fall-back procedure for a PRC imaging device is described. The apparatus includes a PRC controller, a system resource monitor, and a PRC setting calculator. The PRC controller outputs a stream of images at an adjustable temporal rate. The adjustable temporal rate is constrained within a range defined by a first predetermined rate and a second predetermined rate. The system resource monitor obtains a measurement of system resource utilization. The PRC setting calculator determines a setting for the PRC controller in response to the measurement of system resource utilization. Additionally, the PRC controller determines a value for the adjustable temporal rate in response to the setting.

    摘要: Multiple Description Coding (MDC) has been shown to be an effective technique for robust transmission of video data over networks including wireless systems and the Internet. A method is provided where the video signal (20) is interlaced and split into multiple streams before being encoded and transmitted over separate transmission channels (308, 310). At a receiver (320) side, de-interlacing algorithms may be applied and the streams are regrouped to form the original video signal (20). The use of interlacing and deinterlacing techniques improve the robustness of video transmission without having to modify existing equipment.

    摘要: A de-interlacing device and method are provided that may be used in a memory based video processor. The de-interlacer mixes the output of a temporal de-interlacer and a spatial de-interlacer. Two separate error values are used; one for the temporal de-interlacer and another for the spatial de-interlacer. The de-interlacing device calculates from the two error values, using a non-linear mapping, a mix factor used to mix between the outputs of the spatial and temporal de-interlacers.

    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).
