The Research of Background Noise Suppression Method Based on Morphology for Infrared Small Target

红外成像是监测飞行器飞行姿态、精确跟踪飞行器的有效外测方法。在高空飞行器呈现小目标状态下对背景噪声的抑制,是提升光电跟踪质量的有效途径。通过分析噪声来源,明确噪声性质;采用形态学方法对图像进行滤波处理,应用Matlab进行仿真分析,引入信噪比和对比度作为图像处理效果的评价指标,明确采用圆盘结果的开运算方法是背景噪声抑制的有效方法,并提出下阶段工作方向。

Infrared target tracking is an effective method for monitoring the attitude of the aircraft and tracking the aircraft accurately. The suppression of background noise is an effective way to improve the quality of Electro-optical tracking the aircraft when the aircraft far away in the sky. By analyzing the source of noise, we can explicit the properties of the noise. Filtering images by using morphology filters through Matlab and introducing the SNR and contrast as the evaluation of the image effect, we get the conclusion is that the opening operation with disk is the best method for background noise suppression, at last, we get the direction of research in the future.
