    摘要: A video filter processes a video input signal that includes a plurality of pixels in a plurality of macroblocks. The video filter includes an edge detector that processes a selected group of the plurality of pixels to generate a edge identification signal that identifies edge pixels in the selected group, wherein the edge detector is adapted based on a quantization parameter of at least one macroblock corresponding to the selected group of the plurality of pixels. An adaptive deblocking filter is coupled to receive the video input signal and to produce a processed video signal in response thereto, the adaptive deblocking filter being adaptive based on the edge identification signal.

    摘要: A method and system for extracting an inexact rectangular region into an axis-aligned rectangle image. One example method may include identifying vertices for a rectangular frame within a digital image. A rotation matrix is calculated for rotating the rectangular frame to obtain a rotated rectangular frame. The matrix minimizes the sum total of the squared vertical distances between horizontally aligned vertices and the squared horizontal distances between vertically aligned vertices of the rotated rectangular frame. The method further includes applying the rotation matrix to the rectangular frame to obtain the rotated rectangular frame.

    摘要: A method of automatically estimating the layout of a sequentially ordered series of frames to be used to form a panorama comprises examining frames of the series to determine an initial flow direction and identifying a first interruption in the series of frames. The frames are then ranked in an evenly ranked matrix according to matrix dimensions based at least partly upon the initial flow direction and characteristics of the first interruption. An apparatus and computer readable media embodying a computer program for automatically estimating the layout of a sequentially ordered series of frames to be used to form a panorama are also provided.

    摘要: A method of estimating and compensating for jitter between two video frames in a digital video sequence comprises comparing a pixel subset in one video frame to candidate matching pixel subsets within a search area in the other video frame to obtain a preliminary matching pixel subset. Based on the location of the preliminary matching pixel subset, an adapted search area is formed and the comparing is continued within the adapted search area to obtain a final matching pixel subset. Motion is calculated between the video frames based on the final match thereby to estimate the jitter. The video frames are then transformed based on the estimated jitter.

    摘要: A method of determining motion in a set of input images comprises registering the images in the set to identify stationary background content therein and generating difference images based on the registered images. The input images are segmented into regions and local motion within each of the regions is estimated. A determination as to whether the regions include moving content or static content is determined based on the difference images and the estimated local motion within the regions.
