摘要 提出了一种基于边缘特征调整滤波尺寸的中值滤波算法用于小目标的检测。以图像像素的四个方向的边缘分量确定阈值,以此阈值判断像素是否为小目标区域,在此基础上调整滤波尺寸,采用中值滤波方法检测出小目标。结果表明,该算法对于小目标检测有很好的效果。 That a new median filter has the adaptive variable filter size based on edge component is proposed for the detection of dim point target. Threshold based on pixel edge components decides whether any pixel is potential dim tar- gets or not. The median filter have different filter sizes based on the threshold is used for detect the dim point. The re- sults demonstrate the proposed method is very suitable in the field of dim target detection.
