The EuclidVision patents describe a method of analyzing, modeling, and synthesizing video signals which results in several benefits, the most dramatic of which is a new method by which the size of the video is reduced, with no loss in visual quality.
Euclid has significantly advanced the protection of its current implementations of the technology with its most recent application filing in late 2009. This filing takes the patent coverage beyond conceptual research, to the most commercially viable implementation of the EuclidVision hybrid codec. In this patent application, Euclid extends the intellectual property coverage to include feature based modeling – a significant advancement in video compression technology.
The EuclidVision technology patents are interrelated and each patent builds on a new aspect or application of the advancements and innovations described in the preceding patents. All the patents are based on the first patent filed (and granted). The first patent includes 10 foundational claims for analyzing, modeling, and synthesizing video signals. By securing each of the component aspects of the technology through individual patent protection, Euclid Discoveries is effectively securing ownership of a significant amount of the space related to bridging from conventional block-based compression to object and feature modeling compression.
The novelty of the inventions center around the application of key modeling techniques to “simplify” the video before applying an empirically derived linear decomposition, such as Principal Component Analysis (PCA). The simplification of the data effectively removes many of the characteristics of the data that would normally preclude the application of such decomposition. Researchers generally consider the application of PCA to represent a theoretical maximum in terms of representational power, yet they also readily recognize the difficulty of applying PCA directly to the data. EuclidVision is able to perform this direct application to the data after simplifying the data through a process that includes segmentation and normalization of the data to isolate signal modes and make them stationary.
Patent Summary
Euclid has 15 granted patents (US - 7, Australia - 4, China - 3, Japan - 1). In addition, Euclid has 59 patent applications being prosecuted. Euclid’s active filings include 3 USPTO application filings and 56 International (PCT and individual country) application filings. Seventy-seven patents/applications have been published and can be viewed via the appropriate government agency patent office.
Euclid’s patent filings to date are cumulative, documenting essentially a single set of inter-related inventions at progressive points in development. Accordingly, from a Patent and Trademark Office (PTO) viewpoint, subsequent filings are continuations-in-part of previous filings.
To date, 192 claims have been granted.
