1. A system, comprising:
a first processor configured to receive image input data from a red-green-blue infrared (RGBIR) sensor, the image input data comprising RGBIR image data;
a second processor coupled to the first processor, the second processor configured to:
receive first intermediate image data from the first processor;
separate red-green-blue (RGB) image data of the first intermediate image data from infrared (IR) image data of the first intermediate image data to generate second intermediate image data that includes the red-green-blue (RGB) image data and third intermediate image data that includes the infrared (IR) image data;
a third processor coupled to the second processor, the third processor configured to receive the third intermediate image data from the second processor and to process the third intermediate image data; and
a fourth processor coupled to the second processor, the fourth processor configured to receive the second intermediate image data from the second processor and to process the second intermediate image data.
