1. A system of tracking playing chips, the system comprising:
a chip tray for receiving the playing chips;
a camera preprogrammed with one or more image signal processing features to generate image data based on optimized sensor sensitivity values, the camera positioned to capture the image data of the playing chips, the camera having the at least one of the one or more image signal processing features disabled to generate the image data based on static sensor sensitivity values;
a light emitting device emitting a light according to a light emitting device distribution pattern towards the playing chips;
a diffuser positioned between the light emitting device and the playing chips, the diffuser modifying the light into a diffused light emitted according to a second light distribution pattern, the second light distribution pattern distributing light more uniformly, relative to the light emitting device distribution pattern, incident on the playing chips, the second light distribution pattern calibrated to reflect the diffused light incident on the playing chips towards the camera, wherein the camera static sensor sensitivity values perceive reflected diffused light within a normalized feature range; and
a processor in communication the camera and a memory, the processor configured to:
receive, from the camera, the image data reflective of the playing chips illuminated by the diffused light;
process the image data with a classifier, the classifier trained to:
identify chip locations of the playing chips and one or more chip types associated with each chip location by comparing the image data to reference image data reflective of reflected diffused light incident on reference playing chips illuminated by the diffused light and captured with a reference camera having the static sensor sensitivity values for perceiving reflected diffused light within the normalized feature range; and
determine a series of amounts reflective of an amount of chip locations associated with each of the one or more chip types; and
transmit the series of amounts to a game monitoring server.
