A study on the application of Plateau equalization algorithm for contrast enhancement of real-time thermal image

Plateau equalization 알고리즘을 적용한 실시간 열영상 대조비 개선에 관한 연구

Real-time thermal image is obtained by thermal imaging systems measuring radiant emittence according to law of Plank's blackbody radiation. The histogram of thermal image is not uniform. The signal bands of background and target are separated and grouped in narrow bands. In such a system, contrast enhancement indispensible to distinguish target from background. In this study, plateau histogram equalization using local histogram is proposed for contrast enhancement.
