Dynamic range compression for thermal video

Abstract:

Various embodiments of the present disclosure may include an imaging system that allows for absolute radiometry of low dynamic range (LDR) radiometric images down-sampled from high dynamic range (HDR) radiometric thermal images. The imaging system may capture HDR images. The HDR images may be converted to LDR images by a transfer function. In certain embodiments, a video and/or a stream of HDR images may be captured. A sequence of frames may be defined for at least a plurality of the HDR images. Each of the HDR images of the sequence of frames may be converted to LDR images using the same transfer function.
