The paper presents a distance combination scheme based on HSI ( hue, saturation and intensity ) so as to capture more accurate edge data in RGB color field. 为了在RGB3维彩色场中获取精确的边缘信息,提出了一种基于HIS(色度、饱和度和亮度)的距离联合边缘检测方法。
We reduce the affection of the light in the edge detection using the characteristics of hue, saturation and intensity of the separation. 利用HSI模型色度、饱和度与强度分离的特性,以及色度分量不变特性来降低光照在障碍物边缘检测中的影响。
Otherwise color is represented by its hue and saturation, thus the influence of intensity is ignored. 而当亮度和饱和度都大于各自的阈值时,颜色由其色调和饱和度来代表,而忽略不同亮度的影响。
The projective histograms of hue and saturation discribe the color distribution in space, and the projective histogram of intensity reflects the shape of the image. 色调和饱和度的投影直方图反映了颜色的空间分布,而亮度的投影直方图则体现了图像的形状。
