Doble Back-Projection License Plate Recognition Framework
نویسندگان
چکیده
In this paper, a novel algorithm for a car license recognition system is presented. We employ a double back-projection super-resolution image enhancement technique. Modification of initial guess estimation idea has resulted in accuracy improvement and convergence speed up. Bi-lateral back-projection filtering scheme which has been employed as an advanced preprocessor can achieve edge-preserving image smoothing by incorporating the additional information from the feature domain. After computing such processed input video sequence with respect to affine motion model Irani and Peleg’s back-projection algorithm may be applied. Moreover, we consider single mobile camera image acquisition case. Our solution is fully unsupervised and gives excellent optical recognition results. Keywords-super-resolution, license plate recognition

Multi-frame Super Resolution for Improving Vehicle Licence Plate Recognition
License plate recognition (LPR) by digital image processing, which is widely used in traffic monitor and control, is one of the most important goals in Intelligent Transportation System (ITS). In real ITS, the resolution of input images are not very high since technology challenges and cost of high resolution cameras. However, when the license plate image is taken at low resolution, the license...

متن کاملReal Time Implementation of a License Plate Location Recognition System Based on Adaptive Morphology
License plate recognition (LPR) by using morphology has the advantage of resistance to brightness changes; high speed processing, and low complexity. However these approaches are sensitive to the distance of the plate from the camera and imaging angle. Various assumptions reported in other works might be unrealistic and cause major problems in practical experiences. In this paper we considered ...

متن کاملA Design Flow for Robust License Plate Localization and Recognition in Complex Scenes
In this paper, we present a new design flow for robust license plate localization and recognition. The algorithm consists of three stages: 1) license plate localization; 2) character segmentation; and 3) feature extraction and character recognition. The algorithm uses Mexican hat operator for edge detection and Euler number of a binary image for identifying the license plate region. A pre-proce...
