In real-world applications, factors such as head pose variation, occlusion, and poor image quality make facial expression recognition (FER) an open challenge. In this paper, a novel conditional convolutional neural network enhanced random forest (CoNERF) is proposed for FER in unconstrained environment. Our method extracts robust deep salient features from saliency-guided facial patches to reduce...
Interactive learning in class or off-class is crucial to teaching and learning. In this paper, we propose an intelligent learning system for supporting student interactive learning through engagement study, which is based on three modules, i.e., attendance management, teacher-student (T&S) communication, visual focus of attention(VFOA) recognition. Attendance management matches the student's identity...
Topological consistency which plays an important role in land-use map is a difficult problem for map auto generalization. This paper concentrates on the topological preserving of river's dimension-reducing generalization in the land-use map. We propose a method for handling the conflicting constraints involved in generalizing a river polygon (double-line river) into a single-line river. It includes...
Spatial data quality (data accuracy, precision, consistency and so on) is a key issue in Geographic Information System. Geographical boundary inconsistency will directly affect the correctness and efficiency of analysis in GIS application. This paper describes a framework for checking and correcting geographical boundary inconsistency. Two kinds of inconsistency are identified: geometric inconsistency...
The large number of Web-page documents is comprise high dimensional huge text database with the development of Internet technology. But it is only a very small portion with the relevant users. The Web-page should be assigned to a category structure through the Web-page classification technology. it is not only convenient for customers to browse Web-page, but also easier to make Web-page seek through...
