This paper presents an automatic photographic composition method based on convolutional neural network. Firstly, photographic composition rules are adopted for photographic composition assessment, including the rule of third, horizontal line, leading line, scale and texture information. Then, the scores obtained by the aforementioned rules are used to train the Convolutional Neural Network (CNN)....
Three dimensional (3D) zinc oxide (ZnO) nanoflowers have been successfully synthesized on oxidized silver clusters using a vapor transportation method on a 50nm Ag layer. One dimensional (1D) ZnO nanorods can be fabricated on even the thinner Ag layers (2nm and 10nm). During the heating process, with a trace amount of oxygen present, the Ag layer (50nm) melted and agglomerated forming silver oxide...
The exiting covariance matching method is not suited for real-time applications due to its demand for exhaustive search. Aiming at this problem, we developed a novel approach based on fuzzy genetic algorithm (GA) to boost the computing efficiency of covariance matching. The approach employs GA in searching for optimal solution in a large image region. To avoid premature convergence or local optimum...
This paper analyzes the performance of object tracking algorithms. The issues that affect precision in object tracking are analyzed first and how the parameters in tracking algorithms affect the precision in object tracking are introduced. Then, the time complexity of those object-tracking algorithms is discussed. At last, the holistic analysis and evaluation of these object-tacking algorithms are...
This paper proposes an effective framework to boost the efficiency of covariance matching. In this framework, covariance matrices are used to match object in complex environment by fusing multiple features. Then, Genetic Algorithm (GA) is employed to improve the processing speed of covariance matching. To take advantage of the property of GA for the optimization in large search spaces to covariance...
By analyzing the traditional workflow access control models and UCON core model, a UCONTR model based on UCON and capable of supporting distributed workflow is proposed in this paper. The introduction of role and task is the critical differentiator of UCONTR relative to UCON. Then formalized description and analysis of the model are presented. Finally, the implemental architecture of UCONTR model...
Usage control model is presented recently and has been considered as the next generation control model which is used to access digital objects. To be directed against in management function and distributed, multi-domain dynamic environment, this paper puts forward a specific application UCON model -RBUCON which is based on the core model of UCON. With the way of role, domain, protective domain, the...
