Abstract
In one aspect, the present disclosure relates to a method for removing noise from a digital video sequence containing a modulated light signal emitted from a beacon light source. In some embodiments, the method includes electronically receiving, by an image sensor of a device, a digital video sequence of a scene, calculating noise from the digital video sequence, wherein the noise comprises information within the digital video sequence corresponding to the un-modulated illumination of the scene, reducing the noise from the digital video sequence to obtain an isolated digital video sequence of the modulated illumination of the scene, and demodulating the emitted light signal from the isolated digital video sequence.
