| 摘 要： | 提出了一种改进的视频图像中雨滴去除方法.通过分析雨滴的物理光学特性,首先将连续5帧的视频图像存储在一个数组中,并求该5帧图像的同一像素点的最大、最小值；再将最大、最小值作差,当差值大于0时,证明该点被雨滴覆盖；然后将要处理图像的该点分别与最大、最小值作差,并取绝对值,当该点与最小值的差值大于与最大值的差值时,用最小值取代该点的灰度值；最后将该方法与Nayar帧时差法进行比较.实验表明,该方法能够更好地去处视频图像中的雨滴.

| Abstract: | This paper proposes an improved method to remove the rain in video images.By analyzing the physical optics properties of raindrops,firstly five consecutive video images were saved into an array and then found the maximum and minimum values of the same pixel point in the five images.When the difference of the maximum and minimum values is above zero,it proves that this pixel point is covered by raindrops.Then compare the difference between the maximum (minimum)value and the value of the same pixel point of t... |
