Abstract | A new recognition system for the car license plate is designed in view of the low accuracy and the lost time of the identification program in a complex environment, such as low and varying light or strange noisy. The algorithm is composed of five steps: the image preprocessing, the position and segmentation of the license plate, the characters cutting, the feature extraction and the character recognition. It extracts the features based on the multi-scale wavelet. The recognition for characters used the RBF neural network. The new adaptive strategy for raising the speed of recognition is proposed by decreasing the number of some existing hidden layers and the dimension of some features from the wavelet. The experiment results of the actual images show that the average recognition rate can reach more than 92% and the average recognition spend is less 0.11 s than the existing RBF algorithm. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
