摘要: 提出了一个新的红外小目标图像质量评定标准——背景干扰程度,定义了"目标混淆度"和"目标遮隐度"两个指标,它们分别体现了背景噪声引入虚警的能力和背景噪声遮隐目标的能力,设计实现了利用两个指标对背景干扰程度的定量描述.实验证明,与传统的小目标图像评定标准信噪比相比,利用该标准评定的结果与实际情况更加符合,更准确地描述了研究者所关心的检测识别目标难易程度的信息,同时,该标准对于无目标信息情况下小目标图像的质量评定也是有意义的.

Abstract: A new criterion named interferential degree of background was proposed to estimate the quality of infrared small target image. It was described quantitatively by two indicators, one is ‘confusion degree of background upon target’ which represents the ability of the background providing false targets, the other is ‘shielding degree of background upon target’ which represents the ability of the background shielding the target. Experimental results show that the results estimated by this criterion are more consistent with the facts compared with traditional methods (SNR, signal to noise ratio), and they can provide more accurate information about the difficulty degree of detecting or recognizing the targets which is concerned by the researchers. Meanwhile, the criterion is valuable for quality estimation of small infrared target image which does not contain the information of the target.
