| 摘 要： | 针对红外图像对比度差、信噪比低的特点，将提升格式小波变换和Snake模型相结合，提出了一种红外图像边缘增强与分割算法。该算法先采用提升格式小波变换对原图像进行增强，以提升图像中目标与背景的对比度；而后再利用Snake模型对目标的边缘进行提取，最终实现目标的边缘分割。实验结果验证了这种算法可有效地对红外图像的对比度进行提升，从而提取出更为精确的目标边缘。

| Abstract: | For the infrared image with characteristics of low contrast and low signal-to-noise， an algorithm for infrared target enhancement and segmentation, which is based on the lifting scheme wavelet transform and the snake model, is presented. Firstly, the lifting scheme wavelet transform is adopted to enhance the infrared image, and then the snake model is utilized to extract target edge information. Finally，the infrared image enhancement and segmentation is achieved . The experi- mental result validates that the presented method can achieve good results compared with other methods. |
