Multiple-object tracking and team identification for game strategy analysis

A non-transitory computer-readable storage medium storing a set of instructions that is executable by a processor, the set of instructions, when executed by the processor, causing the processor to perform operations comprising:

• updating a reference image based on a first image, wherein the reference image is representative of a statistical model of a background scene, including multiple color values for each pixel within the reference image;
• locating a first plurality of foregrounds in the first image by comparing the reference image with the first image;
• computing for each foreground from the first plurality of foregrounds foreground parameters, measuring foreground's image and real-world characteristics;
• and
• assigning an object track to each foreground from the first plurality of foregrounds if, based on the foreground parameters, it was determined to be representative of a single one of a plurality of pre-selected objects, and wherein the object track is a data structure including a position, an ROI (region of interest), and a color.

A system for automatically tracking multiple objects in a video stream, comprising:

• an object position system that tracks data for a three-dimensional position, a velocity, and an identity of each one of the objects;
• a non-transitory memory device that stores information relating to the object data and executable program code;
• and
• a processor executing the program code to,
• update a reference image based on a first image, wherein the reference image is representative of a statistical model of a background scene, including multiple color values for each pixel within the reference image;
• locate a first plurality of foregrounds in the first image by comparing the reference image with the first image;
• compute for each foreground from the first plurality of foregrounds foreground parameters, measuring foreground's image and real-world characteristics;
• and
• assign an object track to each foreground from the first plurality of foregrounds if, based on the foreground parameters, it was determined to be representative of a single one of a plurality of pre-selected objects, and wherein the object track is a data structure including a position, an ROI (region of interest), and a color,
• the software element further comprising a manager module to compile and output the object data.
