Abstract

In this study, a contrast enhancement method for thermography, namely Adaptive Trilateral Contrast Enhancement (ATCE) is presented. Unlike conventional contrast enhancement methods which aim to exaggerate the contrast difference between fore- and background of an image as a means to improve the image visual quality, ATCE provides a multifaceted approach which involves enhancement of both image contrast and subtle image details. The designation of "trilateral" is derived from the working principle of ATCE which utilises three different type of image characteristics, namely the image contrast (IC), image sharpness (IS) and image intensity (II), to concurrently enhance the visual quality of an image. In the experiment on a collection of thermal images captured under low-light night time environment, ATCE is evaluated and compared to some existing contrast enhancement methods. The qualitative and quantitative experiment results show that ATCE significantly surpasses other existing method on the measure of contrast enhancement.
