Facial recognition for multi-stream video using high probability group

A computer program product, comprising a tangible machine-readable storage medium having encoded therein executable code of one or more software programs, wherein the one or more software programs when executed by at least one processing device perform the following steps:

• maintaining a first database of facial images of a plurality of individuals;
• maintaining a second database of facial images comprising a subset of the individuals from the first database of images, wherein the subset is obtained based on a probability of individuals appearing in one or more sequences of image frames at a given time;
• obtaining the one or more sequences of image frames generated by one or more cameras;
• applying a face detection algorithm to at least one of the sequences of image frames to identify one or more faces in the one or more sequences of images;
• and
• applying a facial recognition to at least one sequence of image frames using at least the second database to identify one or more individuals in the at least one sequence of image frames.

An apparatus, comprising:

• a memory;
• and
• at least one processing device, coupled to the memory, operative to implement the following steps:
• maintaining a first database of facial images of a plurality of individuals;
• maintaining a second database of facial images comprising a subset of the individuals from the first database of images, wherein the subset is obtained based on a probability of individuals appearing in one or more sequences of image frames at a given time;
• obtaining the one or more sequences of image frames generated by one or more cameras;
• applying a face detection algorithm to at least one of the sequences of image frames to identify one or more faces in the one or more sequences of images;
• and
• applying a facial recognition to at least one sequence of image frames using at least the second database to identify one or more individuals in the at least one sequence of image frames.
