A treatise to vision enhancement and color fusion techniques in night vision devices

摘要

In this article a vast literary and ample historic review has been examined to provide in detail introduction, knowledge and comparison of night vision imaging techniques. It unveils night vision enhancement methods described in the recent times such as contrast enhancement; color transfer based clustering, fast color contrast enhancement and pseudo-color fusion algorithm for self-adaptive enhancement system along many others. Furthermore, the scientific and mathematical details are elaborated along with the mechanisms used image fusion techniques, color mapping, histogram matching and statistical evaluation. Conclusively, the channel based color fusion technique stood out through statistical and perceptual analysis.
