摘要

为了从红外热图像中识别和跟踪目标

提出了一种采用数学形态学和小波变换相结合的红外图像处理新方法。该方法首先利用形态开、闭滤波器组对原始图像进行平滑处理;然后采用一种改进的数学形态学的分水岭算法对红外图像进行分割

同时利用考虑了图像纹理信息的小波阈值对分割的图像进行滤波处理;最后针对过分割问题提出了一种利用区域灰度中值对分割区域进行融合处理的算法。实验结果及算法性能评估结果表明

该方法能够较好地解决红外目标的识别问题

具有较好的实用性。

Abstract

In the purpose of recognizing and tracking targets from infrared thermal images

an infrared image processing algorithm based on mathematical morphology and wavelet transform was presented. A original image was smoothed with the open and close filters of mathematical morphology

then the infrared image was segmented with improved watershed

simultaneously

the segmented image was processed with the wavelet threshold with picture texture information. For the problem of over-segmentation regions

an effective region merging method was settled to fuse the segmentation region using the region gray median. The experiment results and algorithm performance evaluation show that the method performs well in infrared target recognition and has a good practicability.
