In this article, the database of sEMG corresponding to the six gestures with two,four and eight channels is collected and established through increasing the number of surface electrode muscle telecommunication reasonably.Two-channel method used in the previous studies in laboratory is improved to make the method suitable for four-channel and eight-channel.On this basis ,the activity of sEMG is detected,the...
With the popularity of digital camera and the application requirement of digitalized document images, using digital cameras to digitalize document images has become an irresistible trend. However, the warping of the document surface impacts on the quality of the OCR (Optical Character Recognition) recognition system seriously. This paper presents a warped document image mosaicing method based on inflection...
Based on the rough set theory and variable granular theorem, a kind of decision information system of off-line handwritten Chinese character recognition is constructed. The performance index entropy in this decision information system is defined in this paper. According to the definition of attribute relative significance, the feature attributes are classified, that the representation of feature attributes...
