The need to quantify aleatory and epistemic uncertainties has been widely recognized in the engineering applications. Aleatory uncertainty arises from inherent randomness, whereas epistemic uncertainty is due to the lack of knowledge. Traditionally uncertainty has been quantified by probability measures and the two uncertainty components are not readily differentiated. Intervals naturally capture...
Video artificial text detection is a challenging problem of pattern recognition. Current methods which are usually based on edge, texture, connected domain, feature or learning are always limited by size, location, language of artificial text in video. To solve the problems mentioned above, this paper applied SOM (Self-Organizing Map) based on supervised learning to video artificial text detection...
In order to detect and diagnosis the exceptional signals, this paper presents a new computer aided test and diagnosis (CAT/CAD) model based on wavelet transform (WT) and support vector machine (SVM). The architecture of the CAT and CAD model and experimental feature extraction and pattern recognition by WT-SVM system are presented. The features of special frequency segment of the signal picked up...
