Hough transform based motion detection image recording system and method
First Claim
1. A method for motion detection image recording, comprising:
- generating a baseline feature segment associated with a surveillance site;
generating a baseline histogram associated with the baseline feature segment;
receiving real-time image data corresponding to the surveillance site;
detecting a real-time feature segment associated with the surveillance site from the real-time image data;
generating a real-time histogram associated with the real-time feature segment;
comparing the real-time feature segment with the baseline feature segment by comparing the baseline histogram to the real-time histogram; and
recording the real-time image data if the comparison of the real-time feature segment with the baseline feature segment exceeds a feature segment criteria.

Abstract
A Hough based motion detection image recording system includes an image sensor operable to view a surveillance site and output real-time image data corresponding to the site. The system also includes a processor operable to receive the image data from the image sensor and a memory coupled to the processor. The system includes a transformation application residing in the memory and executable by the processor. The transformation application is operable to detect a real-time feature segment associated with the site from the image data. The system further includes an analysis engine residing in the memory and executable by the processor. The analysis engine is operable to compare the real-time feature segment with a baseline feature segment and initiate recording of the image data if the feature segment comparison exceeds a predetermined criteria.
