Problems solved by technology

As far as DWT is concerned, more complex artifacts occur when there is a mismatch between the underlying function and some textures, and this causes blurring effects

Embodiment Construction

[0037] In video signal data, video frames are assembled into a sequence of images usually depicting a three-dimensional scene projected (imaged) on 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.

[0038] The present invention analyzes signal data and identifies salient components as illustrated in FIG. 2 . When the signal consists of video data, spatio-temporal flow analysis reveals salient components that are often specific objects (eg, faces). The recognition program defines ...

Abstract

Ail 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
