License plate detection and character recognition have unveiled new possibilities and challenges in the field of intelligent transport system. Numerous algorithms have been proposed regarding license plate localization and tracking, character segmentation and character recognition. License plate character recognition is still an active area of research specially in terms of processing complexity....
Aiming at the seeds of biological stability genetic character, we present a method to feature extraction based on visual invariance. By analyzing the weed seeds and hilum shape characteristics, nine shape features and seven moment invariants of visual invariance were extracted. Back Propagation (BP) Neural Network was used to identify weed seeds, and the relationship between the change of features...
Mobile platforms usually have highly versatile resources. To be a successful interface solution for mobile devices, OCR should have high computational efficiency and adaptation to platform diversity, which are usually trivial in a desktop system, in addition to good recognition rate. In this paper, a practical case study is presented, in which an OCR software is reformed from desktop to embedded version...
