Guiding young learners' attention improves their self-directed learning skills, and that attention can be analyzed via the learners' eye movements. Thus, we propose a self-directed learning system integrating eye trackers with a web based interface to provide an attention guiding function that aims at notifying the learners about the ignored or the skipped parts from the learning material as well...
With the popularization of mobile devices and cloud storages, people tend to store photos and videos through internet. Recently many cloud systems start providing functions to produce reviewing films from stored media files. However, the background music of the film usually does not match the video's emotion because the added music is usually selected randomly. This work proposed an emotion-based...
In this paper, a face recognition method based on sparse representation is proposed. First it represents the test sample as a linear combination of all the training samples and selects K (K = 1, 2, 3) training samples from every class with the bigger contribution by using the representation result of every test sample. Then the test samples are represented as a linear combination of the selected training...
Performing Content-Based Image Retrieval (CBIR) on Internet connected databases through Peer-to-Peer (P2P) network (P2P-CBIR) effectively explores the large-scale image database distributed over connected peers. In additional to enlarge the retrieval scale from server-client to P2P networks, the required computation and network traffics for performing CBIR can also be distributed. Decentralized unstructured...
SQL injection attacks, a class of injection flaw in which specially crafted input strings leads to illegal queries to databases, are one of the topmost threats to web applications. A number of research prototypes and commercial products that maintain the queries structure in web applications have been developed. But these techniques either fail to address the full scope of the problem or have limitations...
