1. An imaging system comprising:
a first infrared (IR) imaging device configured to generate first IR image data of a first field of view of the first IR imaging device at a first time; and
a computing device operably connected with the first IR imaging device, wherein the computing device is configured to:
receive the first IR image data from the first IR imaging device;
determine a first set of pixels from amongst a plurality of pixels associated with the first IR image data, wherein each pixel in the first set of pixels includes first IR image data indicative of the presence of a detection gas;
determine a second set of pixels from amongst the plurality of pixels associated with the first IR image data, wherein each pixel in the second set of pixels includes first IR image data indicative of the absence of the detection gas;
determine a first modification protocol for the first set of pixels;
determine a second modification protocol for the second set of pixels; and
generate a recursive modification input based upon the first modification protocol and the second modification protocol;
wherein the first modification protocol defines a rate at which the first IR image data for one or more pixels in the first set of pixels is replaced and the second modification protocol defines a rate at which the first IR image data for one or more pixels in the second set of pixels is replaced; and
wherein the rate defined by the first modification protocol is less frequent than the rate defined by the second modification protocol.
