| 摘 要： | 提出了一种新的考虑到HIS颜色空间和颜色纯度的多尺度遥感影像分割方法.使用HIS颜色空间来取得像素的颜色信息.当饱和度和亮度值较低时,色调值会非常敏感,用颜色纯度作色调值的加权值.不但考虑了像素的属性,还考虑了像素集合的属性.图像先被根据特定尺度分割成不同的区域对象,各个区域对象的平均值和方差值作为区域对象的属性.用区域对象特性和相对位置信息把小的对象合并到大的对象中.

| Abstract: | A novel method to segment remotely sensed image is proposed considering HIS Color Space, the color purity and Mutil-scale Characteristics. HIS color space is used to express pixel color information. Not only the pixel properties but also the pixel region properties are considered. An image is divided into region. For each region, the mean and variance values can be seen as the pixel region properties. Because the hue value will be very sensitive when the intensity and saturation values are small, the color purity is used as the weight on the hue value. The image segmentation is done with the approach of the combination of region growing based on Mutil-scale Characteristics, and then use features of regions and the relative position information to merge small region into large region. |
