Real-time object tracking using motion and visual characteristics for intelligent video analytics systems

A system comprising:

• a memory device;
• and
• a processing device coupled to the memory device, wherein the processing device is to:
• obtain, based on a first set of images depicting an environment, a first visual appearance descriptor associated with a first object included in the environment, wherein the first set of images is generated during a first time period, and wherein the first object is subsequently absent from the environment depicted in a second set of images generated during a second time period;
• obtain, based on a third set of images depicting the environment, a second visual appearance descriptor associated with a second object included in the environment, wherein the third set of images is generated during a third time period that is subsequent to the second time period;
• obtain a compound similarity metric between the first object and the second object in view of a visual appearance similarity metric and a motion similarity metric, wherein the visual appearance similarity metric corresponds to a degree of similarity between the first visual appearance descriptor and the second visual appearance descriptor;
• and
• responsive to determining that the compound similarity metric meets a threshold value, update an identifier associated with the second object to correspond to an identifier associated with the first object.

A non-transitory computer readable storage medium comprising instructions that, when executed by a processing device, cause the processing device to:

• obtain, based on a first set of images depicting an environment, a first visual appearance descriptor associated with a first object included in the environment, wherein the first set of images is generated during a first time period, and wherein the first object is subsequently absent from the environment depicted in a second set of images generated during a second time period;
• obtain, based on a third set of images depicting the environment, a second visual appearance descriptor associated with a second object included in the environment, wherein the third set of images is generated during a third time period that is subsequent to the second time period;
• obtain a compound similarity metric between the first object and the second object in view of a visual appearance similarity metric and a motion similarity metric, wherein the visual appearance similarity metric corresponds to a degree of similarity between the first visual appearance descriptor and the second visual appearance descriptor;
• and
• responsive to determining that the compound similarity metric meets a threshold value, update an identifier associated with the second object to correspond to an identifier associated with the first object.
