This paper presents a new approach to compensating affine distortion of an isolated online handwritten Chinese character. The input sample is first analyzed by using a character-structure-guided orientation estimation approach. If necessary, the orientation hypotheses are refined based on confidence evaluation of two pre-classifiers. Depending on the number of possible orientations, an HMM-based minimax...
Port state control (PSC) inspection is the most important mechanism to ensure world marine safe. Recently, some SVM-based risk assessment systems have been presented in the world. They estimate the risk of each candidate ship based on its generic factors and history inspection factors to select high-risk one before conducting on-board PSC inspection. However, how to improve the performance of the...
By combining Fractional Spectral Subtraction (FSS) with Perceptual Linear Predictive (PLP), a hybrid method of noise robustness speech recognition isinvestigated in this paper. This method uses FSS for noisy speech to reduce noise components in the fractional Fourier domain. According to the results ofcomputing Itakura distance and Mean Square Error (MSE), an approximate optimal fractional order is...
