Abstract
Various techniques are disclosed to provide for detection of temporally anomalous flickering pixels. In one example, a method includes capturing, by a thermal imager of an imaging device, a plurality of thermal images in response to infrared radiation received from a uniform black body, wherein the thermal images comprise a plurality of pixels having associated pixel values. The method also includes determining, for each pixel, a standard deviation of the associated pixel values for the thermal images. The method also includes comparing the standard deviations with a threshold. The method also includes identifying a subset of the pixels as temporally anomalous pixels in response to the comparing. Additional methods, devices, and systems are also provided.
