System and method for vehicle control based on red color and green color detection

A vehicle image processing system, comprising:

• an imaging system which captures a color image, the color image including a traffic indicator having a color portion;
• and
• a processor operably connected for computer communication to the imaging system, wherein the processor receives the color image from the imaging system, wherein the processor extracts red color components from the color image and green color components from the color image by subtracting grayscale intensity values of each pixel in the color image from respective red-scale values and green-scale values of each pixel in the color image,
• wherein the processor performs blob analysis based on the red color components and the green color components, and determines, based on the blob analysis, a color of the color portion of the traffic indicator, wherein the processor executes control of a vehicle system of a vehicle based on the color of the color portion of the traffic indicator.

A non-transitory computer-readable storage medium including instructions that when executed by a processor, cause the processor to:

• receive a color image from an imaging system, the color image including a traffic indicator having a color portion;
• extract red color components from the color image by subtracting a grayscale intensity value of each pixel in the color image from a red-scale value of each pixel in the color image;
• extract green color components from the color image by subtracting the grayscale intensity value of each pixel in the color image from a green-scale value of each pixel in the color image;
• perform blob analysis based on the red color components and the green color components;
• determine, based on the blob analysis, a color of the color portion of the traffic indicator;
• and
• control a vehicle system of a vehicle based on the color of the color portion of the traffic indicator.
