1. A headcount determination system comprising:
a first camera; and
a processing unit configured to receive data communications that include an image frame captured by the first camera, the processing unit configured to access logic that, when executed, causes performance of operations including:
a pre-processing phase including performing a color channel swap process by reordering color channels of the image frame from a first ordering to a second ordering and dividing the image frame into sub-frames,
an inference phase including deploying a machine learning (ML) model on the sub-frames resulting in a scoring of each sub-frame, performing a threshold comparison with a score of each sub-frame and a threshold, and incrementing a headcount when the score satisfies the threshold comparison, and
when the threshold comparison has been performed scoring each sub-frame, providing the headcount as output.
