During the late few years, research in recognition of handwritten Chinese and Japanese characters has matured significantly. However, in order to obtain high recognition rate, most character recognition systems have paid extremely expensive computational cost. For high performance character recognition systems, how to reduce the expensive computational cost is a very important problem now. Disc...

• Colour, texture and gloss can be used to characterise the visual appearance of a surface. Proposed methodology for raw data processing Reflectance Transformation Imaging (RTI) extraction feature, saliency distance measurement maps. Resulting in automated mapping condition assessment monitoring conservation-restoration treatments. Application on late-Roman bronze coin. techniques, along with t...

A health index, Mahalanobis distance (MD), is proposed to indicate the health condition of cooling fan and induction motor based on vibration signal. Anomaly detection and fault classification are accomplished by comparing MDs, which are calculated based on the feature data set extracted from the vibration signals under normal and abnormal conditions. Since MD is a non-negative and non-Gaussian...

Using the EEG Motor Movement/Imagery database there is proposed an off-line analysis for a brain computer interface (BCI) paradigm. The purpose of the quantitative research is to compare classifier in order to determinate which of them has highest rates of classification. The power spectral density method is used to evaluate the (de)synchronizations that appear on Mu rhythm. The features extrac...

Electro-acupuncture stimulation (EAS) technique applies the electrical nerve stimulation therapy on traditional acupuncture points to restore the muscle tension. The rapid promotion and development of brain-computer interface (BCI) technology makes the thought-control of EAS possible. This paper designed a new BCI-control-EAS (BCICEAS) system by using event-related desynchronization (ERD) of EE...

An electronic nose (EN) is an artificial olfactory system that tries to perform the same task as human olfactory system and widely used in the gas analysis field. EN consists of an array of chemical sensors possessing broad specificity, coupled to electronics and software that allow feature extraction – extraction of salient data for further analysis, together with pattern recognition – identif...

In the case of using the Mahalanobis distance as discriminant function, usually the covariance matrix calculated from training samples is used. However, it is extremely difficult to prepare enough training samples if the dimension of feature vector is large. Therefore, estimated eigenvalues and eigenvectors of covariance matrix will include errors that cause misclassification. In this paper, a ...

PURPOSE To develop and compare the ability of several automated classifiers to differentiate between normal and glaucomatous eyes based on the quantitative assessment of summary data reports from Stratus optical coherence tomography (OCT; Carl Zeiss Meditec Inc., Dublin, CA) in a Chinese population in Taiwan. METHODS One randomly selected eye from each of 89 patients with glaucoma and each of...

We propose a new image segmentation technique called strings. A string is a variational deformable model that is learned from a collection of example objects rather than built from a priori analytical or geometrical knowledge. As opposed to existing approaches, an object boundary is represented by a one-dimensional multivariate curve in functional space, a feature function, rather than by a poi...
