摘　　要：提出了一种基于自适应阈值和限定角点区域的红外图像边缘增强方法.首先介绍了SUSAN边缘增强算法,然后改进了SUSAN算法阈值的自适应选取和角点区域限定的方法,最后在实际应用中,提取出了红外图像清晰、连通的边缘特征.实验结果表明,改进后的方法能够有效地增强红外图像的边缘,得到令人满意的效果.A new method to enhance the edge of infrared image was given, which is based on the adaptive threshold and the comer limited in an appointed sector. The SUSAN operator is introduced, and an improved method to get the adaptive threshold and limit the comer in an appointed sector is presented. The clear and continuous edges of infrared image were got in practical application. Experimental results show that the new method can enhance effectively the edge of infrared image and the result is satisfied.
