Saliency Detection based on Global Color Distribution and Active Contour Analysis
( Zhengping Hu ),( Zhenbin Zhang ),( Zhe Sun ),( Shuhuan Zhao ) 한국인터넷정보학회 2016 KSII Transactions on Internet and Information Syst Vol.10 No.12
In computer vision, salient object is important to extract the useful information of foreground. With active contour analysis acting as the core in this paper, we propose a bottom-up saliency detection algorithm combining with the Bayesian model and the global color distribution. Under the supports of active contour model, a more accurate foreground can be obtained as a foundation for the Bayesian model and the global color distribution. Furthermore, we establish a contour-based selection mechanism to optimize the global-color distribution, which is an effective revising approach for the Bayesian model as well. To obtain an excellent object contour, we firstly intensify the object region in the source gray-scale image by a seed-based method. The final saliency map can be detected after weighting the color distribution to the Bayesian saliency map, after both of the two components are available. The contribution of this paper is that, comparing the Harris-based convex hull algorithm, the active contour can extract a more accurate and non-convex foreground. Moreover, the global color distribution can solve the saliency-scattered drawback of Bayesian model, by the mutual complementation. According to the detected results, the final saliency maps generated with considering the global color distribution and active contour are much-improved.

중국 근대교육의 탄생과 발전의 과정 중 서양의 영향은 매우 중요한 요인 중에 하나이다. 교회대학은 불평등 조약의 보호를 받으면서 특수한 역사의 조건 하에 출현한 서양교육의 전달자 역할을 하며 중국에 약 70여 년간 존재하였다. 교회대학이 존재한 이 시기는 중국교육이 전통교육에서 현대교육으로 전환되는 중요한 시기이다. 70여 년간 교회대학은 중국교육의 현대화에 기여한 많은 인재를 배출하였으며, 근대 여성교육의 발전을 촉진하였다. 전통적인 봉건교육이 기울어가고 사라져가는 역사적인 과정 속에서, 대체적으로 보았을 때 교회대학은 중국교육의 현대화 과정을 가속화하였다. 근대식 교육의 탄생과 발전의 측면에서 말하자면, 교회대학은 다양한 방식으로 이러한 과정을 추진하는 데 있어서 일정한 공헌을 하였다. Western influence was regarded as one of the important factors in the generation and development process of China modem education. As the carrier of western education that appeared in the particular historical circumstances and under the protection of the unfair treaties, church university had existed in the mainland of China for more than 70 years. And this period was exactly the important time that the Chinese education was transmitted from tradition to modernity. During these years, the church university had cultivated a batch of talents for the Chinese education modernization as well as promoted the development of modem woman education in China. All in all, the church universities had accelerated but had not suspended the process of the traditional feudalistic education to decline, collapse and even die out. For the generation and development of China modem education, church universities had made a certain contributions to promote the process in a variety of ways.

Mesoporous silica supported catalysts with highly dispersed Pd particles located in their pore channels were synthesized via a novel and simple two-solvents approach. It is found that the support morphology has significant effect on active phase dispersion. Both the pore diameter and pore length of the silica hosts are critical for the catalytic performances of prepared catalysts. Catalyst with plateletlike morphology (Pd/S-P) shows the highest catalytic activity with 90% toluene conversion at 192 8C. The catalytic performances of the synthesized catalysts are closely correlated with Pd dispersion, CO2desorption capability, pore diameter and pore length of the host materials.
DISPERSION OF PRISTINE MULTI-WALLED CARBON NANOTUBES IN COMMON ORGANIC SOLVENTS
GUOXING SUN,ZHENGPING LIU,GUANGMING CHEN 성균관대학교(자연과학캠퍼스) 성균나노과학기술원 2010 NANO Vol.5 No.2
The dispersion of pristine multi-walled carbon nanotubes in various common organic solvents and water has been investigated. Sedimentation tests, optical microscopy, transmission electron microscopy and Tyndall effect tests are employed. The results clearly show that N-methyl-2-pyrrolodone, acetone, tetrahydrofuran and dichloromethane are good solvents to debundle and disperse the multi-walled carbon nanotubes. In contrast, much precipitation can be obviously observed for systems of the carbon nanotubes in water, ethanol and toluene. Additionally, Tyndall effect tests suggest that the upper dispersions of the carbon nanotubes in acetone, tetrahydrofuran and dichloromethane with a concentration of 0.1 mg/mL and the dispersion of carbon nanotubes in N-methyl-2-pyrrolodone with a concentration of 0.05 mg/mL are colloidal systems rather than solutions. Finally, based on the above results, a possible mechanism is briefly discussed.
