| 摘 要： | 紫外成像技术已广泛应用于各个领域,但紫外图像中的噪声严重影响了图像的质量。分析了日盲紫外图像的噪声特点,采用多帧平均方法和时域递归滤波算法对日盲紫外图像的噪声进行了处理。仿真实验表明:这两种算法均可用于紫外图像的降噪处理,提高了图像的信噪比,特别是时域递归滤波算法。

| Abstract: | Ultraviolet image technology is widely applied in military and civil field,noise of the solar blind ultraviolet image influences image quality seriously.In this paper,the characteristics of noise of the solar blind ultraviolet image are analyzed and noise of solar blind ultraviolet is processed by use of multi-frame average method and time-recursive filtering algorithm.Results of simulated experiment demonstrate that both of these two methods can be used to reduce noise of UV image and improve the Signal Noise Ratio(SNR),especially the latter. |

| Keywords: | ultraviolet image random noise multi-frame average time-recursive filtering |
