SYSTEM AND METHOD FOR DETECTING LIGHT SOURCES IN A MULTI-ILLUMINATED ENVIRONMENT USING A COMPOSITE RGB-IR SENSOR

A system and a method for detecting light sources in a multi-illuminated environment using a composite red-green-blue-infrared (RGB-IR) sensor is provided. The method comprises detecting, by the composite RGB-IR sensor, a multi-illuminant area using a visible raw image and a near-infrared (NIR) raw...

description	A system and a method for detecting light sources in a multi-illuminated environment using a composite red-green-blue-infrared (RGB-IR) sensor is provided. The method comprises detecting, by the composite RGB-IR sensor, a multi-illuminant area using a visible raw image and a near-infrared (NIR) raw image of a composite RGBIR image, dividing each of the visible raw image and the NIR raw image into a plurality of grid samples, extracting a plurality of illuminant features based on a green/NIR pixel ratio and a blue/NIR pixel ratio, estimating at least one illuminant feature for each grid sample by passing each grid sample through a convolution neural network (CNN) module using the extracted plurality of illuminant features, and smoothing each grid sample based on the estimated at least one illuminant feature.
