Embodiment Construction

[0043] Exemplary embodiments of the invention are described below. In video signal data, video frames are assembled into a sequence of images typically depicting a three-dimensional scene imaged projected onto a two-dimensional imaging surface. Each frame (or image) is made up of pixels representing imaging sensors that respond to sampled signals. Often times, the sampled signal corresponds to some reflected, refracted, or emitted energy (eg, electromagnetic energy, acoustic energy, etc.) sampled by the two-dimensional array of sensitive elements. Successive sequential sampling results in a spatio-temporal data stream, with two spatial dimensions and one temporal dimension for each picture corresponding to the order of the picture in the video sequence.

[0044] The present invention is as figure 2 Analyze signal data and identify significant components as illustrated. When the signal consists of video data, spatio-temporal flow analysis reveals salient components that are...

Abstract

An apparatus and methods for processing video data are described. The invention provides a representation of video data that can be used to assess agreement between the data and a fitting model for a particular parameterization of the data. This allows the comparison of different parameterization techniques and the selection of the optimum one for continued video processing of the particular data. The representation can be utilized in intermediate form as part of a larger process or as a feedback mechanism for processing video data. When utilized in its intermediate form, the invention can be used in processes for storage, enhancement, refinement, feature extraction, compression, coding, and transmission of video data. The invention serves to extract salient information in a robust and efficient manner while addressing the problems typically associated with video data sources.

Description

[0001] related application [0002] This application is a continuation-in-part of and claims the benefit of US Provisional Application No. 60 / 811,890, filed June 8, 2006. The entire teaching of the above application is hereby incorporated by reference. field of invention [0003] The present invention relates generally to the field of digital signal processing, and more particularly to computer apparatus and computer-implemented methods for the efficient representation and processing of signal or image data, in particular video data. Background technique [0004] The prior art generic system description in which the present invention resides can be used figure 1 express. The block diagram here shows a typical prior art video processing system. Such systems generally include the following stages: an input stage 102 , a processing stage 104 , an output stage 106 and one or more data storage mechanisms 108 . [0005] The input stage 102 may include several elements such as ...
