Abstract
In this paper, we report our experimentation to enhance the quality of the thermal images acquired with ordinary digital camera, after replacing the infrared stopping filter with visual stopping one. The Red, Green, Blue histograms indicate very low intensities captured by the respective sensors. Histogram stretching increased the hot objects’ and the inherent noise visibility. Finally lowpass as well median filtering were applied, where the later is best for suppressing granular noise and maintaining the intended thermal images.
