Research on Segmentation Methods of Weed and Soil Background Under HSI Color Model

In view of the complex background in the weed detection, the research used the H component under HSI the color model to divide the soil background. Considered the real-time operation, it used the automatic threshold value segmentation method, and carried on the suitable erosion and dilation, realized the weed area and the background area segmentation. The result indicated that it was possible of using above methods to obtain suited to segmentation of color space and the color characteristic component; therefore, it was practical and effective for threshold value parameter as the attribute image color information to segment weed from background area.
