Because of the single directionality of the strong beam and the uniform distribution energy of the weak target, it is feasible for the detection of the weak image the strong beam disturbance. In the detection of the weak target image, the background is regarded as a kind of texture and the existence of the weak target changes the local textural features. To use the multiple correlation analysis for getting textural features, we can detect the weak target image. The multiple correlation analysis...

Because of the single directionality of the strong beam and the uniform distribution energy of the weak target, it is feasible for the detection of the weak image the strong beam disturbance. In the detection of the weak target image, the background is regarded as a kind of texture and the existence of the weak target changes the local textural features. To use the multiple correlation analysis for getting textural features, we can detect the weak target image. The multiple correlation analysis is also used for judging whether the image filtering is going on or not. It has been proved as an effective detection means in the experiments.

由于强光束的方向性和弱目标的各向同性 ,采用具有方向选择特征的多尺度、多频道Gabor滤波器组来抑制强光束 ,并在此基础上采用纹理驱动的相关分析算法来检测弱目标图像 .实验证明这是一种有效的检测手段 .

The problem of enhancing and detecting target in a sequence of images recorded by a long-range infrared sensor is investigated. To highlight the difference between warm object and background, a new algorithm of infrared image enhancement based on local textural features is presented. To improve the speed and accuracy of target detection, the relative information among sequential images is used to detect and track the target at the same time. Experimental results show that the enhancing algorithm can highlight...

To improve the speed and accuracy of target detection, the relative information among sequential images is used to detect and track the target at the same time. Experimental results show that the enhancing algorithm can highlight the warm objects and depress the background and improve the speed and accuracy of target detection.

文中主要研究了远距离红外图像序列的目标增强和检测问题,提出了基于局部纹理特征的红外图像增强算法,利用红外图像目标和背景区域局部纹理特征的差异来增强目标和背景区域的对比度;为了提高目标检测的速度和精度,利用序列图像的帧间相关信息,采用边检测边跟踪边确认的目标检测方法。实验结果表明,对于远距离、小目标的红外图像,这种增强算法在目标对比度和细节方面都明显优于直方图均衡化方法,而本文采用的目标检测方法仅需很少几帧图像就能检测和跟踪目标,可以在确保目标检测的可靠性的前提下,提高目标的检测速度。
