User assisted customization of automated video surveillance systems
A surveillance system allows a user to characterize the user's environment and/or the user s surveillance application, via a selection from among a variety of predefined environments and/or applications. Preferably, the selection is from among a variety of scene configurations, such as the expected number and type of targets in a typical scene, the lighting conditions of the scene, and so on. The selected environments and/or applications effect a determination of the parameters that are used in the various algorithms and processing modules within the surveillance system. Because the selection is preferably from a variety of common scene configurations, no technical skills are required to effect an optimization of the performance of the surveillance system for a particular environment.
1. A computer readable medium embodying a set of instructions executable by a computer for determining one or more parameters of at least one of a plurality of function modules including at least one people-detection module, at least one object-detection module and at least one vehicle-detection module in a surveillance system, the set instructions comprising the steps of:
providing a plurality of scene characterizations including a plurality of people-image characterizations for the people-detection module, a plurality of object-image characterizations for the object-detection module and a plurality of vehicle-image characterizations for the vehicle-detection module to a user;
receiving a selected characterization by the user;
determining whether the selected characterization is a people-image characterization, an object-image characterization or a vehicle-image characterization;
determining the one or more parameters based on the selected characterization; and
communicating the one or more determined parameters to a corresponding function module according to the determined type of the selected characterization so as to cause the corresponding module to apply the one or more determined parameters to provide a corresponding functional effect based on the one or more determined parameters.
2. The computer readable medium of claim 1 , wherein the one or more parameters include at least one of a size parameter, a shape parameter, and a speed parameter.
3. The computer readable medium of claim 1 , wherein
each people-image characterization of the plurality of people-image characterizations corresponds to a number of people accommodated within a video image; and
each vehicle-image characterization of the plurality of vehicle-image characterizations corresponds to a number of vehicles accommodated within the video image.
4. The computer readable medium of claim 3 , wherein
the plurality of function modules includes a detecting module that is configured to detect people-images, and
at least one of the one or more parameters of the detecting module is dependent upon the number of people-images accommodated within the video image.
5. The computer readable medium of claim 4 , wherein the one or more parameters of the detecting module include at least one of a size parameter, a shape parameter, and a speed parameter.
6. The computer readable medium of claim 3 , wherein
the plurality of function modules includes a detecting module that is configured to detect object-images, and
at least one of the one or more parameters of the detecting module is dependent upon the number of people-images accommodated within the video image.
7. The computer readable medium of claim 6 , wherein
the plurality of function modules includes a detecting module that is configured to detect vehicle-images, and
at least one of the one or more parameters of the detecting module is dependent upon the number of vehicle-images accommodated within the video image.
8. The computer readable medium of claim 7 , wherein the one or more parameters of the detecting module include at least one of a size parameter, a shape parameter, and a speed parameter.
9. The computer readable medium of claim 1 , wherein the plurality of scene characterizations corresponds to at least one of a variety of camera orientations, a variety of lighting conditions, and a variety of fields of view.
10. The computer readable medium of claim 1 , wherein
the plurality of scene characterizations are provided as a plurality of icons corresponding to a variety of fields of view, and
the selection of one or more select characterizations corresponds to user selections from among the plurality of icons.
11. The computer readable medium of claim 1 , further including the one or more function modules.
12. The computer readable medium of claim 11 , wherein the instructions further include the steps of:
processing at least one output from the plurality of function modules, and
producing therefrom one or more alerts to the user.
13. The computer readable medium of claim 11 , wherein the instructions further include the steps of:
consolidating multiple outputs from the plurality of function modules, and
using one or more parameters based on the one or more select characterizations.
