A primary factor in the design of an e-learning or e-testing system lies in the proper grading of a given set of vocabulary or phrases. This paper proposes an automatic system that can learn to do the fundamental word's difficulty grading once taught by a domain expert. As a comparison, two approaches are used to analyze the system: the former is a rule-based system which requires a complete knowledge...
A speech synthesis system is designed for automatically recognizing visual speech generated by the speech impaired and present a new communication approach for the speech-impaired people. In order to acquire more parameters of lip contours, a new model is made up, which can extract the degree of pouting from it. At the same time, the differential coefficients of some parameters are calculated to describe...
There are some usual methods in vehicle license plate location, such as segmentation in grey-level image, color image edge extraction and neural networks filters etc. All these methods are proved not quite satisfactory in various conditions, or are influenced by some factors. In this paper, we present to classify colors of pixels by using improved neural networks, which include 27 nodes of input layer,...
