In this paper, we present an accurate and robust license plate localization approach based on the Support Vector Machine (SVM) classifier. We impose the license plate localization as a classifier based binary recognition problem. The images of our database exhibit various illumination conditions (daytime, dark night). For the problem of illumination effects, we use the algorithm of Scale Invariant...
In order to protect the copyright of digital productions, a novel watermarking algorithm based on feature points and singular value decomposition (SVD) is presented. By introducing the SIFT's key points matching and geometric distortion estimation, the attacked watermarked image can be corrected and the watermark synchronization is realized. In this way, the feature regions detected by the Harris...
At present, the biometric verification methods have attracted more and more the attention of researchers, and palm print verification as an important method, with its stable and rich features, has been widely used and highly development prospects. However,in feature extraction stage, traditional Gabor often uses fixed parameters to extract feature of all samples, which is not only a waste of a great...
