TECHNIQUE ON IMAGE RECOGNITION OF TRAFFIC SIGNS, CAPABLE OF BECOMING STRONG IN ILLUMINATION CHANGE IMPLEMENTING THE ACCURATE AND STRONG PERFORMANCE OF THE IMAGE RECOGNITION OF THE TRAFFIC SIGNS, AND A SYSTEM THEREOF

摘要

PURPOSE: A technique on image recognition of traffic signs and a system thereof are provided to recognize various sizes of traffic signals with a multi-scale generating and processing unit and to use a learned property for the recognition of the traffic signs by learning and predicting a property of the traffic signals extracted by a property extracting unit with a property learning unit.;CONSTITUTION: A traffic sign recognition system includes a multi-scale generating and processing unit (100), a property extracting unit (200), and a property learning unit (300). The multi-scale generating and processing unit generates a scale of input images and different color format images and recognizes various sizes of traffic signs. The property extracting unit extracts properties of the recognized traffic signs. The property extracting unit learns and predicts the property extracted from traffic sign images and the images except for the same.;COPYRIGHT KIPO 2013;[Reference numerals] (100) Multi-scale generating and processing unit; (200) Feature extraction unit; (300) Feature learning unit; (AA) Driving image input; (BB) Recognized result output; (CC) Data flow required for the recognition of a traffic sign
