MULTI-RESOLUTION VIDEO ANALYSIS AND KEY FEATURE PRESERVING VIDEO REDUCTION STRATEGY FOR (REAL-TIME) VEHICLE TRACKING AND SPEED ENFORCEMENT SYSTEMS
First Claim
1. A video-based analysis system comprising:
- an image capturing device that captures video stream data having video data frames at a first high resolution;
a vehicle detection module that detects at least one vehicle within the video data frames;
a vehicle analysis module that is configured to analyze the video data frames containing the detected vehicle and to extract or tag one or more key vehicle features from the video data frames to enable identification of a vehicle of interest (VOI) according to a set of predetermined criteria; and
a subsampling module that creates a reduced resolution video stream in a second subsampled resolution that is lower than the first high resolution while maintaining the one or more extracted key features within the reduced resolution video stream in the first high resolution, and archives the reduced resolution video stream into a video database.

Abstract
Systems and methods are disclosed that include a video-based analysis system that detects, tracks and archives vehicles in video stream data at multiple resolutions. The system includes an image capturing device that captures video stream data having video at a first high resolution. A vehicle detection module detects at least one vehicle within the video. A vehicle analysis module is configured to analyze the video and to extract one or more key vehicle features from the video to enable identification of a vehicle of interest (VOI) according to a set of predetermined criteria. A subsampling module creates a reduced resolution video stream in a second subsampled resolution that is lower than the first high resolution while maintaining the one or more extracted key features within the reduced resolution video stream in the first high resolution, and archives the reduced resolution video stream into a video database.

11. A video-based analysis and tracking system comprising:
-
a vehicle analysis module that analyzes video data frames containing a detected vehicle and extracts a plurality of key vehicle features from the video to identify a vehicle of interest (VOI) according to a set of predetermined criteria and vehicle analytic data provided thereto; and a subsampling module that reduces resolution of the video stream data to a second lower resolution that is at least one of a spatial resolution and a temporal resolution while maintaining at least one of the extracted key features in the first resolution and archives the video at the second resolution into a video database. - View Dependent Claims (12, 13, 14, 15)

16. A method for a video analysis system executed via at least one processor with a memory storing executable instructions to execute the method, comprising:
-
capturing video stream data having video data frames at a first high resolution in an image capture device; detecting a vehicle within the video data frames with a detection module; extracting one or more key vehicle features from the video data frames having the vehicle detected; identifying a vehicle of interest according to a set of predetermined criteria related to vehicle analytic data from the video frames having the vehicle detected; reducing the resolution of the video stream data with a subsampling module to a video data stream having a second resolution while maintaining one or more extracted key features in the first resolution that is a higher resolution than the second resolution. - View Dependent Claims (17, 18, 19, 20, 21, 22)
