Dynamic calibration of detection system for active areas of interest within video data

A computer-readable medium that stores program instructions, where the instructions are executable to:

• receive data indicative of active areas of interest detected within respective ones of a plurality of video frames captured by a detection system using a multidimensional filter, wherein the multidimensional filter is configured to identify active areas of interest based at least on part upon a programmable density threshold;
• determine, based on the data indicative of active areas of interest, that the detection system is in an unstable state;
• perform a calibration routine to identify one or more threshold values that reduce system instability;
• and
• instruct the detection system to use the one or more threshold values during operation of the multidimensional filter.

A method of calibrating a video system, comprising:

• generating data indicative of active areas of interest detected within respective ones of a plurality of video frames captured by a detection system using a multidimensional filter, wherein the multidimensional filter is configured to identify active areas of interest based at least on part upon a programmable density threshold;
• determining, based on the data indicative of active areas of interest, that the detection system is in an unstable state;
• performing a calibration routine to identify one or more threshold values that reduce system instability;
• and
• applying the one or more threshold values to the multidimensional filter, thereby reducing detection system instability.
