Real-time video triggering for traffic surveilance and photo enforcement applications using near infrared video acquisition

A system for real-time video triggering comprising:

• a video camera;
• a video receiving module for receiving a streaming video feed from said video camera;
• a resampling module configured to receive said streaming video feed and resample said streaming video to a lower spatial resolution of said streaming video;
• a detection module configured to detect a plurality of motion blobs in said resampled video stream;
• an identification module configured to identify candidate motion blobs from said plurality of motion blobs as candidates for triggering a video collection action;
• and
• an output module wherein said candidate motion blobs are provided to a triggering module configured to trigger a collection action.

A computer program product comprising:

• a computer-usable data carrier storing instructions that, when executed by a computer, cause the computer to perform a method of rear-time video triggering, the method comprising:
• receiving a streaming video feed;
• resampling said streaming video to a lower spatial resolution of said streaming video;
• detecting a plurality of motion blobs in said resampled video stream by at least one of:
• analyzing said resampled video using bi-directional frame to frame differences;
• labeling an initial foreground and background in said resampled video stream;
• and
• applying morphological filtering to said resampled video stream to identify a plurality of motion blobs in said resampled video stream;
• eliminating any motion blob from said plurality of motion blobs in said resampled video stream as a candidate motion blob if a size and aspect ratio of said motion blob are not within a predefined size and aspect ratio range;
• eliminating any motion blob from said remaining plurality of motion blobs at original resolution as a candidate motion blob if a standard deviation of an intensity of said motion blob does not fit a predefined characteristic signature;
• eliminating a motion blob from said remaining plurality of motion blobs at original resolution as a candidate motion blob if said motion blob is not identified as a candidate motion blob by a candidate motion blob classifier video stream as candidates for triggering a video collection action;
• outputting a plurality of coordinates of centroids and a bounding box associated with said candidate motion blobs;
• and
• triggering a video collection action.
