Abstract
A method for object tracking. The method includes capturing, using an optical sensor having first and second sensing matrices, an image of a scene (), analyzing a first pixel of the image to detect imbalanced pixel sensing values from the first and second sensing matrices (), analyzing a second pixel of the image to detect balanced pixel sensing values from the first and second sensing matrices (), comparing the imbalanced pixel sensing values and the balanced pixel sensing values to generate a result (), and determining, based on the result, that a first portion of the scene associated with the first pixel corresponds to a background of the scene, and that a second portion of the scene associated with the second pixel corresponds to a pre-determined light source ().
