Apparatus and method for processing video data
First Claim
1. A computer apparatus for the purpose of generating an encoded form of video signal data from a plurality of video frames, comprising:
- a means for identifying corresponding elements of an object between two or more video frames;
a means for modeling such correspondences to generate correspondence models, where the correspondence models include motion models and appearance models;
a means for segmenting and resampling pel data in said video frames associated with said object, said segmenting and resampling means utilizing said correspondence models, where the re-sampled pel data creates a representation of said object based on finite differences between said video frames, the finite differences implying an interpolant on a neighborhood of pels in said video frames; and
a means for restoring spatial positions of the re-sampled pel data, said restoring means utilizing the correspondence models;
wherein said object is one or more objects, andsaid re-sampled pel data is an intermediate form of original pel data of the object for video processing.

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.
