Hybrid method and system of video and vision based access control for parking stall occupancy determination
First Claim
1. A hybrid method of video and vision based access control for parking occupancy determination, said method comprising:
- acquiring at least one image frame of a parking area of interest from among at least two regions of interest defined with respect to said parking area of interest;
analyzing said at least two regions of interest defined within said parking area of interest for motion detection or content change detection;
performing a vision-based image content classification operation with respect to a first region of interest among said at least two regions of interest based on a result of said content change detection; and
performing an object tracking operation with respect to a second region of interest among said at least two regions of interest if a result of said vision-based image content classification operation indicates a presence of an object of interest within said parking area of interest to thereafter determine a type of access authorized with respect to said parking area of interest and based on a result of said object tracking operation.

Abstract
Hybrid methods, systems and processor-readable media for video and vision based access control for parking occupancy determination. One or more image frames of a parking area of interest can be acquired from among two or more regions of interest defined with respect to the parking area of interest. The regions of interest can be analyzed for motion detection or image content change detection. An image content classification operation can be performed with respect to a first region of interest among the regions of interest based on the result of the image content change detection. An object tracking operation can then be performed with respect to a second region of interest among the regions of interest if the result of the image content classification operation indicates a presence of one or more objects of interest within the parking area of interest.

8. A hybrid system of video and vision based access control for parking occupancy determination, said system comprising:
-
a processor; a data bus coupled to said processor; and a computer-usable medium embodying computer program code, said computer-usable medium being coupled to said data bus, said computer program code comprising instructions executable by said processor and configured for; acquiring at least one image frame of a parking area of interest from among at least two regions of interest defined with respect to said parking area of interest; analyzing said at least two regions of interest defined within said parking area of interest for motion detection or content change detection; performing a vision-based image content classification operation with respect to a first region of interest among said at least two regions of interest based on a result of said content change detection; and performing an object tracking operation with respect to a second region of interest among said at least two regions of interest if a result of said vision-based image content classification operation indicates a presence of an object of interest within said parking area of interest to thereafter determine a type of access authorized with respect to said parking area of interest and based on a result of said object tracking operation. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A non-transitory processor-readable medium storing computer code representing instructions to cause a hybrid process of video and vision based access control for parking occupancy determination, said computer code further comprising code to:
-
acquire at least one image frame of a parking area of interest from among at least two regions of interest defined with respect to said parking area of interest; analyze said at least two regions of interest defined within said parking area of interest for motion detection or content change detection; perform a vision-based image content classification operation with respect to a first region of interest among said at least two regions of interest based on a result of said content change detection; and perform an object tracking operation with respect to a second region of interest among said at least two regions of interest if a result of said vision-based image content classification operation indicates a presence of an object of interest within said parking area of interest to thereafter determine a type of access authorized with respect to said parking area of interest and based on a result of said object tracking operation. - View Dependent Claims (16, 17, 18, 19, 20)
