The book "Traffic-Sign Recognition Systems" offers a comprehensive analysis of the detection and classification of traffic signs. It is based on advanced computer vision methods specifically developed for object recognition. The authors, Sergio Escalera and Xavier Baró, present a generic approach that enables the real-time recognition and classification of various traffic sign classes. The challenges of robust detection and categorization are thoroughly addressed, with a focus on the latest developments in this field. The book provides a detailed methodology for categorizing traffic signs, including the use of Error-Correcting Output Codes and various algorithms that have been experimentally validated. Finally, it offers an outlook on future research directions and existing challenges.
