1. A method of determining one or more properties of one or more items employing an image based counting system comprising:
illuminating, via one or more lighting sources, one or more items having a plurality of illumination characteristics;
capturing a first image via a first imaging device with adjustable focus of the one or more items from a first angle;
capturing second image via a second imaging device of the one or more items from a second angle;
receiving images of the illuminated items from the first and second imaging devices at a control circuitry;
generating a composite image comprising the first and second properties;
identifying a characteristic of the plurality of illumination characteristics of the composite image at the control circuitry;
comparing the characteristic to a list of illumination characteristics that corresponds to a property of the one or more items at the control circuitry;
determining one or more properties of the one or more items based on the comparison at the control circuitry; and
generate an alert associated with the one or more properties at the control circuitry.
