1. An apparatus comprising:
a chip tray comprising columns;
image sensors positioned between at least two adjacent ones of the columns and aligned substantially parallel to a vertical height of the columns, wherein the image sensors have opposing viewpoints from a top and from a bottom of the at least two adjacent ones of the columns; and
a tracking controller configured to perform operations that cause the apparatus to:
capture, via the image sensors, image data of a chip stack in at least one of the at least two adjacent ones of the columns, wherein the image data of the chip stack includes images of the chip stack from the opposing viewpoints;
segment, according to the images of the chip stack from the opposing viewpoints, the chip stack from the image data of the chip stack into an upper portion and a lower portion;
detect, via a machine learning model based on image data of the upper portion and the lower portion, a value of each gaming chip in the chip stack in response analysis of chip-edge features of each gaming chip in the chip stack; and
electronically present information associated with detection of the value of each gaming chip in the chip stack.
