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...
There are the problems such as slow identification, poor anti-interference capability in the traditional edge detection. In this paper, it analyzes the different traditional detection algorithms and experimental results. Based on the analysis, it proposes out the edge detection algorithm based on wavelet, and analyzes the effect of wavelet edge detection.
Wavelet has important apply in image processing and pattern recognition. In 2008, the wavelet technology was applied to Beijing Olympic traffic guidance transmission successfully, by locating and identifying all kinds of vehicles. This paper carries on research about the construction of binary wavelet from the practical need of signal processing and analysis and provides two types of binary wavelet...
The advantage of wavelet technology can separate the signal and the noise, thereby enhancing the output the ratio of signal to noise. In the outdoor environment, under the high noise, it proposes one algorithm based on dyadic wavelet to process the signals and noises in images of vehicles through the wavelet transform at different scales and different characteristics, which can adjust its threshold...
