Abstract: Image detection and recognition algorithms are crucial for developing an intelligent sign inventory system using video log images. The technical challenge is to detect and recognize more than 670 different types of signs ...

Abstract: Sign recognition is crucial not only for road asset inventory but also for intelligent vehicles. Fast and robust sign recognition is still an open problem especially in varying and complex road environments. Speeded-up ...

Abstract: Geometric data in transportation, such as roadway geometry, are important for asset management and for safety analysis. Traditional roadway geometric data are measured in the field, which is time consuming, costly, and ...
