No-Reference Image Quality Assessment Method Based on Visual Parameters

引用

Journal of Electronic Science and Technology 2019年第2期17卷 171-184页

作者： Yu-hong Liu Kai-Fu yang hong-mei yan Key Laboratory for Neuroinformation of Ministry of Education University of Electronic Science and Technology of China Chengdu 610054 China Department of Biomedical Engineering Chengdu Medical College Chengdu 610050 China

Recent studies on no-reference image quality assessment (NR-IQA) methods usually learn to evaluate the image quality by regressing from human subjective scores of the training samples. This study presented an NR-IQA method based on the basic image visual parameters without using human scored image databases in learning. We demonstrated that these features comprised the most basic characteristics for constructing an image and influencing the visual quality of an image. In this paper, the definitions, computational method, and relationships among these visual metrics were described. We subsequently proposed a no-reference assessment function, which was referred to as a visual parameter measurement index (VPMI), based on the integration of these visual metrics to assess image quality. It is established that the maximum of VPMI corresponds to the best quality of the color image. We verified this method using the popular assessment database—image quality assessment database (LIVE), and the results indicated that the proposed method matched better with the subjective assessment of human vision. Compared with other image quality assessment models, it is highly competitive. VPMI has low computational complexity, which makes it promising to implement in real-time image assessment systems.

Study of Relation between EFL Students'Cognitive Style and Pragmatic Competence

Journal of Electronic Science and Technology 2017年第1期15卷 41-47页

作者： Kai-Wen Cheng Yi Wang hong-mei yan Key Laboratory for NeuroInformation of Ministry of Education University of Electronic Science and Technology of ChinaChengdu 610054China Zhejiang University Hangzhou 310058China

Individual difference is one of the important factors affecting the success of learning English as foreign language（EFL）. However, very little research has dabbled in the correlation between pragmatic competence and cognitive styles among college students. Two questionnaires（the embedded figure test and the pragmatic competence test） were designed and used to conduct our study among seniors with non-English majors from key universities. The data was analyzed with SPSS 21.0 and results showed that pragmatic competence of the subjects was much lower than expected. Besides, there was a significant and positive correlation between field dependent（FD）cognitive style and inter-language pragmatic competence while no significant correlation was found with field independent（FI）. A regression model was also formulated to obtain more specific information. Lastly,some practical advice is offered for teachers to boost students＇ pragmatic competence in the future with FD/FI cognitive styles into proper consideration.

作者： Li Ying Tang Zhu Ju Wang mei hong Fu yan He hong Wei Wu Lu Qi Huang Institute of Traditional Chinese Materia Medica Chinese Academy of Medical Sciences Beijing 100700 China

A new anthraquinone glycoside 1, along with a known anthraquinone glycoside aurantio-obmsin-6-O-β-D-glucopyranoside 2, were isolated from the seeds of Cassia obtusifolia. On the basis of spectral and chemical evidences, the structure of 1 was established as 1-demethylaurantio-obtusin-2-O-β-D-glucopyranoside. Moreover, the 13C NMR of 2 was assigned totally and correctly for the first time based on the two-dimensional NMR.

Determination of alcohol compounds using corona discharge ion mobility spectrometry

Ion mobility spectrometry （IMS） is a very fast, highly sensitive, and inexpensive technique, it permits efficient monitoring of volatile organic compounds like alcohols. In this article, positive ion mobility spectra for six alcohol organic compounds have been systematically studied for the first time using a high-resolution IMS apparatus equipped with a discharge ionization source. Utilizing protonated water cluster ions （H2O）nH^＋ as the reactant ions and clean air as the drift gas, alcohol organic compounds, ethanol, 1- propanol, 2-propanol, 1-butanol, 1-pentanol and 2-octanol, all exhibit product ion characteristic peaks in their respective ion mobility spectrometry, that is a result of proton transfer reactions between the alcohols and reaction ions （H2O）nH^＋. The mixture of these alcohols, including two isomers, has been detected, and the results showed that they could be distinguished effectively in the ion mobility spectrum. The reduced mobility values have been determined, which are in very well agreement with the traditional ^63Ni-IMS experimental values. The exponential dilution method was used to calibrate the alcohol concentrations, and a detection limit available for the alcohols is in order of magnitude of a few ng/L.

Non-Linearity of Visual Sensitivity and Pursuit Velocity during Smooth Pursuit Eye Movements

引用

Journal of Electronic Science and Technology 2014年第4期12卷 394-399页

作者： Xu-Fang Chen Tao Deng hong-mei yan the Key Laboratory for Neuro Information of Ministry of Education University of Electronic Science and Technology of China

During pursuit eye movements, whether the relationships among the visual sensitivity, pursuit velocity, and target velocity are linear or non-linear is an old issue. In this study, we reexamined their relationships with seven speeds by a simple character discrimination task using an infrared eye tracker. Our results found that the pursuit velocity and accuracy were non-linearly related with the target velocity. Besides, the perceptual sensitivity was not linearly related with the pursuit velocity either. A significant difference existed between lower （less than 20 deg/s） and higher speeds （greater than 20 deg/s）. In addition, we found there was no position bias of visual sensitivity between ahead of and behind the pursuit target, but there was a significant perceptual dissymmetry between horizontal and vertical directions at lower pursuit speeds.
