Small Target Detection Based on Morphology Filtering and Order Filtering

针对红外图像中弱小目标的检测问题 ,提出了一种基于形态和顺序滤波相结合的小目标检测方法。该方法是采用Top hat变换抑制背景的基础上 ,用门限判决对图像进行预检测。然后用顺序滤波去虚警点从而得到目标点。实验结果表明 ,在信噪比SNR >

Detection of week and small objectors in an infrared image is one of difficulties among image objector detection and identification.A small target detction method based on morphology filtering and order filering is presented to solve the small target detection with low SNR in an infrared image.First the Top Hat transformation suppresses the background of the original image.Then some candidate dots are got by a threshold separation.Finally filtrating the true target by using an order filtering.The experiments show that this method can easily and effectively extract the small target in an infrared image with its SNR>2.
