1. A computer-implemented method for detecting a presence of an object-of-interest in a system, the method comprising: imaging the first object-of-interest including an identifier, wherein the imaging generates a first set of image data; determining the portion of the image data including the identifier based on a predetermined location; dividing the portion of the image data including the identifier into at least two segments; and determining a presence of the object-of-interest by determining if intensity values within each segment exceed a presence threshold.
