In this paper, an improved normalized mutual information feature selection...
Detecting depression via speech is an attractive topic in recent years. Significant correlation was found between speech pause time and depressive severity. In the present study, 92 depressed patients and 92 age-, gender- and education level-matched control participants were examined to investigate three temporal characteristics of speech: recording time (RT), phonation time (PT) and speech pause...
According to the characteristics of fax paper, a method of content-based fax retrieval is put forward. The wavelet decomposition is used in the fax image de-noising, and the wavelet coefficients are used for regional division, and then combined with optical character recognition technology to extract the semantic features of the text region and the shape features of the logo for the fax retrieval...
An identification method was proposed for distinguishing the bloody clams from different populations based on multi-spectral image technology. Three populations of bloody clams were collected from Korea, Shandong, and Zhejiang, respectively. The multi-spectral images of bloody clam shells were acquired by CIR MS3100 multi-spectral camera. The graylevel co-occurrence matrixes (GLCM) of the three sub-images...
