A sensor having a positive temperature coefficient shroud is described, as well as a computing system to control actuation of the positive temperature coefficient shroud. According to one example, the computing system executes a method that actuates the positive temperature coefficient shroud of the sensor based on a transmittance parameter of the sensor. 1. A system , comprising:a processor; and receive, from a sensor coupled to the processor, an image;', 'determine a transmittance parameter of the image; and', 'when the transmittance parameter is less than a transmittance threshold value, then actuate a positive temperature coefficient (PTC) shroud of the sensor, wherein the transmittance threshold value is based on a set of noise values and a set of error values., 'memory storing instructions, executable by the processor, that comprise, to2. The system of claim 1 , further comprising a computer claim 1 , wherein the instructions further comprise claim 1 , to: command the computer to actuate the PTC shroud.3. The system of claim 1 , wherein the sensor comprises an active cooler electrically coupled to the PTC shroud claim 1 , and the instructions further comprise claim 1 , to: when the transmittance parameter is less than a transmittance threshold value claim 1 , then actuate the PTC shroud by actuating the active cooler to an ON state.4. The system of claim 1 , wherein the transmittance threshold value comprises a first transmittance threshold value claim 1 , and further comprising claim 1 , to: actuate the PTC shroud when the transmittance parameter is less than the first transmittance threshold value claim 1 , and not actuate the PTC shroud when the transmittance parameter is greater than the first transmittance threshold value.5. The system of claim 4 , wherein the instructions further comprise claim 4 , to: when the transmittance parameter is greater than the first transmittance threshold value and less than a second transmittance threshold value claim 4 , ...
