红外图像评价质量研究

Image Quality Evaluation of Infrared Image

按照红外图像的形成过程分析可认为一幅红外图像是由目标图像、背景图像和噪声图像,目标图像和背景图像是红外图像的主体,噪声图像是叠加在红外图像主体上的干扰。文章从红外图像主体能提供的信息量是否丰富、细节是否明显,噪声图像相对图像主体的大小三个方面入手,对红外图像进行质量评价,评价结果与主观评价相一致,具有较好的可比性。

An infrared picture is composed of object image, background image and noise image according to the imaging process. The object image and the background image are the key body of an infrared image; noise image is the disturbance on the key body. This paper discusses the infrared image quality from three aspects that if the information capacity of the key body is rich, if the image detail of the key body is sharp, and if the noise image is obviously to the key body. The result of the evaluation shows good consistency with the subjective test.
