| 摘 要： | 通过对水滴运动模糊图像的物理本质进行分析,提出了一种基于频域的水滴运动方向识别方法。通过对运动模糊图像做二维傅立叶变换得到其频谱幅值图,然后利用频谱幅值图中高亮条纹的方向与运动方向相垂直的特性完成对水滴运动方向的识别,高亮条纹的方向采用RADON变换方法加以检测。仿真实验结果表明,该方法可以准确地识别水滴运动方向。

| Abstract: | By analyzing the physical nature of water droplets motion blurred image,a new method based on frequency-domain analysis for identification of water droplet movement direction was put forward. The spectrum image of motion-blur image was firstly obtained by 2D Fourier transformation. Then,utilizing the fact that the highlighted strip was perpendicular to the motion-blur direction,the water droplet movement direction was estimated. The direction of highlighted strip was identified by RADON transformation. The simulated experimental results showed that the novel method could accurately estimate the water droplet movement direction. |
