Traffic flow, analysis and control is gaining high relevance, as the number of circulating vehicles continuously increases. This article proposes a computer vision based platform, which automatically detects vehicles in order to infer the traffic conditions. The developed real time detection algorithm is based on a dual background subtraction technique, incorporating the one known has Codebook and...
This paper presents a novel approach of license plate location. The proposed algorithm involves the following three steps. First, the vertical edges of the vehicle image are extracted by Sobel operator. Second, HSV color space and integral image are employed to locate candidates in yellow license plates and non-yellow license plates. Finally, connected component analysis is to locate the region of...
This paper introduce a method of car license plate location which use the hue component in effect. Strengthen the blue component firstly, then set the appropriate threshold for location according to the regional color information. If no useful, transform the image by HSV, based on strengthening the blue component, and make the other regional black.Thus we can locate the car license plate accurately.
Considering the fact that High Definition (HD) becomes an important trend in road surveillance video, this paper studies vehicle location and license plate location methods in HD surveillance video. While license plate reading may obviously benefit from high definition technology, higher resolution also increases the computational load of graphical analysis and background interference. Most known...
