基于序列图像中运动小目标检测

The Study of Small Target Detection in Sequence Image Based on Correlation of Target between Frames

根据序列胶片图像中运动目标帧间相关特性,提出一种弱小目标检测的方法。采用图像积累的方法,提高信噪比,去除图像背景;采用自适应门限进行阈值分割,得到二值化的图像;利用帧间目标相关的特性去掉噪声点,检测出目标点。实验结果表明,该方法能够有效地提取出低信噪比下序列图像中的微小运动目标。

A detection method for small moving target is proposed according to the COlTelauon oI me target frame - to - frame in sequential images. Image SNR is improved by using energy accumulation meth- od, the background of image is removed. Binaryzation image is obtained through adaptive threshold segmentation. Noise spot is removed and target is detected based on the correlation of target frame - to- frame. The experimental results show that this method can effectively find small target from the sequential images with low SNR.
