| 摘 要： | 提出一种基于HSI彩色空间的加权中值滤波算法,该算法依据人眼对颜色的感知特性,结合颜色的亮度信息和色度信息,并且保持了DDF（The Directional-Distance Filters）滤波器的优点。算法根据彩色图像中颜色的亮度来修改亮度和色度的权值,调整滤波器的输出,在保持图像颜色细节方面比以往的各种矢量中值滤波算法都有一定的提高,更加符合人眼对于颜色的感知特点。

| Abstract: | The weighted algorithm of median filtering based on the HSI color space is provided. The algorithm based on the human eyes to perceive colors, gathered information of brightness and chromaticity and inherited DDF (The Directional-Distance Filters) filter's advantages. The method changes the weights of brightness and chromaticity to adjust the output of the filter according to brightness of the color image and has the certain enhancement in the maintaining details of color image aspect compared to the former each kind of vector median filters. This algorithm even more conforms to the person eyes regarding the color sensation characteristic. |
