| Abstract(in English) | As ITS related researches, techniques for extraction and recognition of road signs are actively researched. We presented a technique for extracting image regions which contain road signs in short time. This technique is constructed by detecting colors used for road signs, called as specific colors, and restricting search regions based on histgrams of the colors. We also presented a road sign type recognition technique by using traced outline vectors in extracted regions. Both techniques are based on specific color detection, so the result accuracy is depend on the detection accuracy. In this report, a new specific color detection technique is proposed. This technique is based on RGB values with small calculation amount. The experimental results show that the detection results are stabler and higher accuracy than former. This result improves recognition accuracy. |
