A new algorithm for image segmentation based on DIS edge detection and adaptive edge growing;

After having a thinning process of edge map, there will be only one edge point in the growth point s eight-neighbor, so there is only one case to analyze,that is a simplified method of edge growing can be implemented to edge map as usual.

An improved image segmentation method based on edge growing is proposed in view of the features of color space.

The analysis of edge students through the thought of strangers creation and development;

Beginning with distorted behaviors of edge students,the author suggests the teachers should use a series of psychology methods to correct distorted behaviors of edge students,which is good for developing harmony and stable campus environment.
