    摘要: A video filter processes a video input signal having a frame type. The video filter includes a horizontal deblocking filter that is coupled to receive the video input signal and to produce a filtered video signal in response thereto. A vertical deblocking filter includes a mode controller that generates a mode control signal based on the frame type. A filter is selectively enabled based on the mode control signal, and wherein, when the filter is selectively enabled, the filter video deblock filters the filtered video signal to generate the processed video signal.

    摘要: A method of preserving the structure of a font character being scaled comprises analyzing the font character to determine if the font character is complex. If the font character is complex, information concerning the strokes forming the font character is extracted. The strokes are then scaled to a desired size using the extracted stroke information thereby to form a scaled font character.

    摘要: A multi-scale method to efficiently determine the fine-scale saturation arising from multi-phase flow in a subsurface reservoir is disclosed. The method includes providing a simulation model that includes a fine-scale grid defining a plurality of fine-scale cells, and a coarse-scale grid defining a plurality of coarse-scale cells that are aggregates of the fine-scale cells. The coarse-scale cells are partitioned into saturation regions responsive to velocity and/or saturation changes from the saturation front. A fine-scale saturation is determined for each region and the saturation regions are assembled to obtain a fine-scale saturation distribution. A visual display can be output responsive to the fine-scale saturation distribution.

    摘要: A method of estimating three-dimensional camera position information from a series of two-dimensional images that form a panorama employs common features in adjoining image pairs in the series to estimate a transform between the images in the pairs. The common features are subsequently employed to adjust an estimated rotational component of each transform by reducing error between coordinates corresponding to the common features in three-dimensional space in image pairs, on a pair-by-pair basis. A global optimization of the position estimation, used for long sequences of images such as 360 degree panoramas, refines the estimates of the rotational and focal length components of the transforms by concurrently reducing error between all 3D common feature coordinates for all adjoining pairs.
