As one of research directions of Intelligent Transportation System (ITS), Cooperative Vehicle Infrastructure System (CVIS) has attracted the attention of domestic and foreign researchers. CVIS is a complex large system, so it is very necessary to simulate and verify the system before put it into use. In this paper, the traffic simulation environment is built, including road network, vehicles, city...
One of the fundamental problems in image search is to learn the ranking functions, i.e., similarity between the textual query and visual image. A number of research paradigms, ranging from feature-based vector model to image ranker learning, have been applied to measure query-image similarity. However, most of the existing similarity learning methods either depend on surrounding texts for ranking...
Visual search reranking is defined as reordering visual documents (images or video clips) based on the initial search results or some auxiliary knowledge to improve the search precision. Conventional approaches to visual search reranking empirically take the “classification performance” as the optimization objective, in which each visual document is determined relevant or not, followed by a process...
