This paper proposes a fast road signs recognition framework with shape filtering and contour features. We observe the standard road signs and construct two basic feature tables for recognition processing. In road driving images, we transfer the RGB color domain to HSV for the red regions detection firstly. And we obtain candidate regions and decide the kinds of shapes by eliminating the redundant...
Adaptive region growing algorithm in color annual ring image segmentation makes good use of color and spatial information of regions, and combined with the edge information so as to adaptive changes growth conditions, solves the problem of the regional fault. Compared to the traditional algorithms, the new one combined with watershed algorithm can select the seeds automatically, the complete shape...
