Image segmentation is an important image analysis technique, the segmentation result of which is critical to determine the performance of high-level modules in image processing system. After a brief introduction LLT image segmentation algorithm, focusing on analysis of the inadequacies of LLT algorithm, propose an improved ILLT image segmentation algorithm. Experiments show that the algorithm improves...
Vehicle identification is one of the key technologies to achieve road transport automation and the deep research of this technology has important practical significance to the development of intelligent transportation. Because image backgrounds of car models are complex, and the count of car models is too large, model identification has long been a research hotspot and difficult. This paper mainly...
In current license plate recognition, there are many problems because of the complex, irregular motion and blur license plate. This paper presents a license tilt detection method, and to improve overall system performance and reliability, proposes some detection algorithms: gravity center method, Hough transform, the method of put vertexes into a line. Simply described their processes, at the same...
A few of classic thinning algorithms are presented. Combing with the advantages of the medial axis approach and the peeling approach, propose a new thinning algorithm, and it has been used to the car plate recognition system. The experiment shows that the new algorithm provides high implement efficiency, good thinning effect, greatly improving the whole performance of car plate recognition system.
Most methods of the tradition character reorganization are based on JPEG and the classifier and then matching with the templates. Due to the environmental of plate with large noise plate and interference factors, the accuracy of this method is relatively low. In this paper, based on the analysis of the traditional method of the character recognition, it uses wavelet processing for image pre-processing,...
This paper discuses the application of wavelet analysis and invariant movements on automatic vehicle recognition. The wavelet analysis was used to get multi-scale edge images, and the invariant moments were used to anti-tilt and anti-interference, and to correct the vehicles of the images. Then we can compare similarity through the Euclidean distance between two images' normalized moment vectors....
