Research on Image Segmentation Algorithm for Vision Navigation
The image is divided utilizing the auto-threshold segmentation method,in which the maximum area method is adopted to determine the initial threshold,and the maximum interclass variance and minimum internalclass variance are applied for the initial segmentation. Considering that road identification are easily interfered by shadow,three special color spaces are designed. Firstly,the initial segmentation is carried out in a bright space,followed by detecting shadow according to the characteristics of the shadow in the other spaces,then then image is divided based on the edge segmentation,and finally the running region of the automobile can be obtained.
