A geometric segmentation method for traffic scenes based on super-pixel label matching is proposed to solve the problem of complex calculation and long time-consumption of model training in the pixel-by-pixel labeling method for traffic scenes. The proposed method does not require model training
and a set of images similar to picture a traffic scene that will be segmented is searched according to global features. Then
super-pixel segmentation and super-pixel block feature extraction are performed on the traffic scene
and the likelihood ratio is calculated using the naive Bayesian principle. Super-pixel block label matching is performed in the set of similar images according to the likelihood ratio to realize an initial segmentation. Finally
the initial segmentation result is used to calculate the unary potential
and the fully connected conditional random field model is used to optimize the initial segmentation result. Experimental results and a comparison with the traditional pixel-by-pixel labeling method show that the proposed method effectively achieves geometric segmentation of traffic scenes
and the accuracy of segmentation and the average recall rate increase by 4% and 3% respectively.
