A mobile terminal voting system based on android platform is presented and implemented to solve the problems of traditional voting and e-voting system in this paper. Joining the static-password mechanism and the dynamic-password mechanism, a double identity authentication scheme is presented based on the symmetric algorithm, which conquers challenge-response protocol weakness. It achieves double identity...
The faces in video sequence of monitoring system are the key information for crime detection, identity recognition and other fields. However, the face is usually blur for the far distance or low-resolution of camera. In this paper, a face super resolution algorithm based on patch reconstruction was presented to enlarge and make face image clear. The face images were segmented from the sequence by...
In this paper, an improved pork freshness detecting method based on color features was presented according to the biochemical mechanism of pork metamorphism. The pork sample images were captured and processed by de-noisy and segmentation methods. Then, the fat areas were eliminated to reduce the influence of detection in HSV color space. A new Color Region Ratio (CRR) extraction method was presented...
Image mosaicing technique is used in creating vast scene images and panoramic images. It has wide application value in the cultural heritage protection and virtual reality field. An automatic algorithm based on feature points of images is presented in this paper. Firstly, feature points are extracted using Harris corner detector to perform correlation. Then, a new method of filtering for matching...
