Advances have been made continuously in detection networks such as SPPnet and Fast R-CNN. Recently the novel region proposal method RPN shares full-image convolutional features with the detection network and enables a state-of-the-art object detection network Faster R-CNN. In this work we apply Faster R-CNN to train a detection network on our digital image database of books and implement automatic...
In this paper, we study a privacy-preserving spectrum sharing system to protect secondary users' location privacy while enhancing spectrum access. The location privacy of secondary users can be compromised by an external adversary via the received signal strength (RSS)-based localization technique. To mitigate such privacy threat, we employ a random power perturbation approach that allows each secondary...
In this paper, we develop a social group utility maximization (SGUM) framework for cooperative networking that takes into account both social relationships and physical coupling among users. Specifically, instead of maximizing its individual utility or the overall network utility, each user aims to maximize its social group utility that hinges heavily on its social ties with other users. We show that...
This paper provides a novel two-stage verification scheme based on watermarking for electronic passport. The watermarking includes the multimodal biometric feature of the passport owner and the parity check codes of multimodal feature. The first part is taken as the template to do field certification which confirms whether the person is the true passport holder. The parity check codes verify the integrity...
Electrocardiogram (ECG) reflects cardiac electrical activity, and varies from person to person, which could be used for biometrics identification. ECG biometrics identification algorithm is presented in this paper based on Matching Pursuit (MP) and Support Vector Machine (SVM). The ECG signal is decomposed into atoms by sparse decomposition with Gabor dictionary which contain ECG signal's important...
Cardinality estimation and tag authentication are two major issues in large-scale Radio Frequency Identification (RFID) systems. While there exist both per-tag and probabilistic approaches for the cardinality estimation, the RFID-oriented authentication protocols are mainly per-tag based: the reader authenticates one tag at each time. For a batch of tags, current RFID systems have to identify them...
This paper discusses the video search engine and learning environment, and proposes construction of a network learning environment which based on video searching technology, meanwhile, which makes learning environment more effectively in improving students' teaching ability for students and teaching ability to provide support to improve performance. The network learning environment based on video...
At present, some of our agri-food products with quality issues, not only turmoil in domestic, but also had credit crisis in the international community. A number of food export enterprises have also been implicated in. Based on agri-food supply chain management, agricultural products retailers or food processing enterprises establishing traceability systems voluntarily is not only a strong guarantee...
