Video Compression - Method for Estimating Motion    

The technology relates to video compression, specifically to a motion estimation search method for a video coding.

Overview

It uses a start point and finds an image point to be another start point along the plurality of search paths from the original start point that has a min comparison value with a reference image block. The cycle repeats until points on search paths have comparison values higher than the start point.

The invented algorithm has higher prediction quality and faster speed. It is very easy to be implemented in hardware and data access is very efficient.

Primary Application of the Technology

Video compression in all the digital encoding devices such as digital video recorder, digital camera, digital video cam, and high-definition video system. The market is huge in portable and home entertainment devices.

Patent Summary

U.S. Patent Classes & Classifications Covered in this listing:

Class 382: Image Analysis

This is the generic class for apparatus and corresponding methods for the automated analysis of an image or recognition of a pattern. Included herein are systems that transform an image for the purpose of (a) enhancing its visual quality prior to recognition, (b) locating and registering the image relative to a sensor or stored prototype, or reducing the amount of image data by discarding irrelevant data, and (c) measuring significant characteristics of the image.

Subclass 107: Motion or velocity measuring
Subclass 291: Determining the position of an object

Class 375: Pulse Or Digital Communications

This is the generic class for pulse or digital communication systems using electrical or electromagnetic signals. Such communication includes transmitting an intelligence bearing signal from one point to another in the form of discrete variations in some parameter of the electrical or electromagnetic signal.

Subclass 240.16: Motion vector
