VIDEO-BASED DETECTOR AND NOTIFIER FOR SHORT-TERM PARKING VIOLATION ENFORCEMENT
First Claim
1. A method for determining the occurrence of a short-term parking violation, the method comprising:
- receiving video data in a sequence of frames provided by an associated image capture device monitoring a parking area over a duration of time;
determining the presence of a vehicle captured in at least one of the sequence of frames;
tracking the location of the vehicle across the sequence of frames, wherein the tracking includes;
determining a spatial location of the vehicle in a plurality of frames, anddetermining spatio-temporal information describing the location of the vehicle as a function of time by associating the spatial location of the vehicle across the plurality of frames with the time instant at which the each frame of the plurality of frames was captured; and
,in response to the spatio-temporal information indicating that the vehicle becomes stationary, determining a duration that the vehicle is stationary using the determined spatio-temporal information of the vehicle.

Abstract
A method for determining the occurrence of a short-term parking violation includes receiving video data in a sequence of frames provided by an image capture device monitoring a parking area over a duration of time. The method includes determining the presence of a vehicle captured in at least one of the sequence of frames. The method tracks the location of the vehicle across the sequence of frames. The method further determines a spatial location of the vehicle in each frame. The method includes determining spatio-temporal information describing the location of the vehicle as a function of time by associating the spatial location of the vehicle at each frame with the time instant at which the frame was captured. In response to the spatio-temporal information indicating that the vehicle becomes stationary, the method determines a duration that the vehicle is stationary using the determined spatio-temporal information of the vehicle.
