Abstract
Methods, systems and processor-readable media for parking occupancy determination. Changes in the field of view can be measured using template matching between templates derived from an original scene and a current scene with motion removed. The changes measured in the field of view can be employed to adjust data indicative of a region of interest for vision-based processing thereof if the changes measured are above a pre-determined threshold so that the impact of the changes with respect to the field of view to performance is minimized.

11. A system for parking occupancy determination, said system comprising:
-
a processor; and a computer-usable medium embodying computer program code, said computer-usable medium capable of communicating with the processor, said computer program code comprising instructions executable by said processor and configured for; measuring changes in a field of view using template matching between templates derived from at least one original scene and at least one current scene with motion removed; and employing said changes measured in said field of view to adjust data indicative of at least one region of interest for vision-based processing thereof if said changes measured are above a pre-determined threshold so that an impact of said changes with respect to said field of view to performance is minimized. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)

20. A processor-readable medium storing code representing instructions to cause a process for parking occupancy determination, said code comprising code to:
-
measure changes in a field of view using template matching between templates derived from at least one original scene and at least one current scene with motion removed; and employ said changes measured in said field of view to adjust data indicative of at least one region of interest for vision-based processing thereof if said changes measured are above a pre-determined threshold so that an impact of said changes with respect to said field of view to performance is minimized.
