摘要： A method and system for analog video noise reduction by blending finite impulse response (FIR) and infinite impulse response (IIR) filtering are provided. A filtering mode may be selected to generate noise-reduced pixels using FIR, IIR, or a blend of FIR/IIR filtering. Blending a current pixel and an FlR-filtered current pixel may generate a first blended current pixel. The FIR filtering may be based on the current pixel, a previous collocated pixel, and a next collocated pixel. Blending the current pixel and an IIR-filtered current pixel may generate a second blended current pixel. Blending the first blended current pixel and the second blended current pixel using an adaptive blending factor may dynamically generate a filtered output pixel. The IIR filtering may be based on the current pixel and a collocated pixel of the previous second blended video image or of the previous filtered output video image.

摘要： A method and a system for video noise reduction based on moving content detection are described. Aspects of a system for processing images may include circuitry within a chip that determines a motion metric that indicates an amount of motion between a current video picture and at least one of the following: at least one preceding video picture and at least one subsequent video picture. The motion metric may be computed from a maximum value derived by summing, over a plurality of corresponding pixels that are located within a region around a reference pixel in a current video picture, differences in values of the plurality of corresponding pixels. The circuitry within the chip may also compute a blending factor that has a nonlinear relationship to the motion metric. The circuitry within the chip may adjust at least one pixel in the current video picture based on the computed blending factor.

摘要： A video and graphics system provides square graphics pixels to blend images having 640×480 pixels, such as graphics images provided by some set top boxes and intended to be displayed at a 12.27 MHz display sample rate, with images having 704×480 pixels, such as ITU-R 601 compliant images such as NTSC SDTV images, having oblong pixels and displayed at a 13.5 MHz display sample rate. A sample rate converter including a multi-phase-multi-tap filter is used to generate square pixels. The multi-phase-multi-tap filter provides a good balance of sharpness, smoothness, anti-aliasing and reduced ringing. The multi-phase-multi-tap filter can also be used to convert images having 320×480 pixels to images having 704×480 pixels. The multi-tap filter can be used for scan rate conversion of graphics or video images for HDTV or SDTV applications.

摘要： Methods are disclosed for performing improved deblocking filtering across edges between macroblocks, with particular application to cases where one macroblock is field coded and its neighbors are frame coded. A method for filtering across horizontal edges comprises determining which macroblocks are considered to be vertically adjacent to each other. The method also determines which macroblocks are considered to be sampled at a same time. Finally, filtering is performed between vertically adjacent macroblocks that are considered to be sampled at a same time. Another method for filtering across vertical edges comprises determining which macroblocks are considered to be horizontally adjacent to each other. The method effectively re-arranges a vertical ordering of horizontal lines of at least a subset of the horizontally adjacent macroblocks. Finally, filtering is performed between the horizontally adjacent macroblocks after the re-arranging.

摘要： A method and apparatus are disclosed for performing motion estimation and compensation to fractional pixel accuracy using polyphase prediction filters as part of a video compression/decompression technique. A motion estimator applies a set of polyphase filters to some data in the reference picture and generates motion vectors, an estimated macroblock of video data, and a residual error macroblock of video data. The data referenced in the reference picture usually have more data than a macroblock since multi-tap filtering needs to access more data. A motion compensator generates a compensated macroblock of video data in response to the reference video data, the residual error macroblock of video data, and a polyphase prediction filter decided by the motion vector. The reference video data are usually reconstructed at the compensator side.

摘要： A system and method for accurate express tolling of highway vehicles. A multilane tolling system comprises a tolling (MVIC) unit that collects information from tolling subsystems arranged to take various vehicle measurements. Preferably, an intelligent vehicle identification subsystem sends vehicle information to the MVIC unit many times per second. Preferably, a vision tracking system (VTS) communicates with the MVIC unit and sends the latter information about the vehicle position using vision tracking sensors. Preferably, an RF subsystem conducts multiple reads of a transponder on a passing vehicle and forwards the read information to the MVIC unit. Preferably, a vehicle image capture unit (VICU) captures images of the passing vehicle when a camera in the VICU receives a trigger from the MVIC unit. Preferably, a driver alert module is used alert a driver passing through a tolling point as to account balance associated with a silent toll tag or pay by plate system.
