Our primary motivation in this paper is to determine whether evolved texture feature extraction programs are competitive with human derived programs for a difficult real world texture classification problem. The problem involves distinguishing images of three classes of bulk malt. There are subtle differences between the three classes. We have used a number of human derived methods, Haralick, Gabor,...
Ranking of fuzzy numbers is an important procedure for many applications in fuzzy theory, in particular, decision-making. In this paper, we propose a new method for ranking fuzzy numbers based on Dice set theoretic index. The Hurwicz criterion which considers all types of decision makers' perspective is employed in aggregating the fuzzy total evidences. The properties of the proposed method are also...
In this paper, we propose a depth perception and motion cue based three-dimensional (3D) video quality assessment (VQA). Depth perception provides the real 3D impression during viewing the 3D video (3DV), and motion cue is also important factor to simulate a Human Visual Systems (HVS) for 3DV. We combine the depth perception and motion cue, and generate a weighting map for 3D VQA. For adjusting contribution...
Intention recognition plays a key role in the cooperation among the humans. An intention describes an action or sequence of actions to be performed for achieving the intended purpose. The cooperating humans learn each others intentions while cooperation. In this paper we propose three ways how a robot can learn the intention of the cooperating human. In the first case, the robot learns the human intention...
In this paper, a method to derive the three predominant synergies and their temporal weights for planning grasps of the UB Hand IV (University of Bologna Hand, version IV) is proposed. The method adopted to define the postural synergies from experiments is based on the kinematic structure of the robotic hand and on the taxonomy of the grasps of common objects. The control strategy, exploiting postural...
This paper focuses on a kinematic redundancy resolution of bimanual robotic system for a machining task as a part of factory automation. Inspired by a study of human bimanual action, called Guiard's principles, a cost function is proposed by using task-compatibility indices. An acceleration-level redundancy resolution is provided via optimization of the cost function in order to reflect the role of...
The human hand is considered one of the most natural tools in human-computer interaction (HCI). In virtual environments, virtual hand interactions play a key role in interactivity and realism [1]. This paper explores the use of hand gestures as a means of human-computer interactions for virtual reality applications. A lifelike hand model is constructed and some of the human hand constraints are applied...
This paper introduced the extension method and established a danger evaluation matter-element model based on debris flow surveying data of Miyun county. The research indicates that it is reasonable and feasible for using extension method in danger division of valley debris flow. It can reflect each factor's influence on danger of valley debris flow. This paper used simple correlation function to determine...
Notions of human wellbeing can be used to evaluate and plan technological innovation and engineering design. However, current engineering practices and most engineering education curricula do not adequately deal with wellbeing. A set of interdisciplinary courses at the University of Puerto Rico, Mayagüez are proposed by the authors to fill this gap and to provide a transition to an engineering curriculum...
The synthesis of multi-fingered grasps on nontrivial objects requires a realistic representation of the contact between the fingers of a robotic hand and an object. In this work, we use a patch contact model to approximate the contact between a rigid object and a deformable anthropomorphic finger. This contact model is utilized in the computation of Independent Contact Regions (ICRs) that have been...
The data of this article are generalized the distribution of meteorological indexes, sedimentation rates, chemical elements (including their state forms) and palinological remnants in the manyaged sediments and deposits thickness of SE Baltic region areas (Pustelnikovas, 2012 a, b, Pustelnikovas et al., 1996, 2012 et al.).
The most fundamental means of maintaining mechanical safety is to systematically carry out safety design and analysis in the mechanical design process. The fuzzy comprehensive evaluation method is to take the advantages of the level analytic hierarchy process and fuzzy comprehensive evaluation method. Firstly, the evaluation index system is divided into ladder level structure, calculated the index...
This Human-Computer Interaction (HCI) is a field in which the developer makes a user friendly system. In this paper, a real-time Human-Computer Interaction based on the hand data glove and k-NN classifier for gesture recognition is proposed. HCI is becoming more and more natural and intuitive to be used. The important part of body that is hand is most frequently used as interaction in digital environment...
To evaluate the ambient air quality status of the Fuxin city in Aug-Nov, 2011, we established fuzzy comprehensive evaluation mathematical model and membership function using lower semi-trapezoid distribution through the distribution of data collection and selecting the main factor affecting air quality, and have the result that urban monthly average air quality has declined with the temperature during...
Sustainable development analysis is the important problem in contemporary domestic and international. The analysis about sustainable development evaluation index system spreads widely in the international, this paper analyzes sustainable development index system of research results in the relevant international organizations and main developed countries. We point out the characteristics of the related...
Existing structural similarity (SSIM) index comprises of one term on luminance comparison and the other term on contrast and structure comparison. In this paper, the SSIM index is first improved by introducing three weighting factors to the second term such that it is adaptive to local intensities of two images to be compared. The improved SSIM (iSSIM) index is further extended for two images with...
Reflectance confocal microscopy (RCM) is a non-invasive and in-vivo imaging modality, which can take images from different depths of the human skin. A challenging problem is to detect a clinically important subsurface section of the skin, the Dermis/Epidermis junction, in RCM images. This is a tough problem because of the huge variation of texture and intensity features across both intersubject and...
China is the largest country to produce and consume Chinese medicine in world. People have come to realize that the side effects of chemical medicine gradually because serious pollution, ecological environment deterioration and human ‘lifestyle disease’ are among the most severe challenges with which human beings are faced today. The voice for “return to nature” becomes louder and louder. To find...
Although vaccination is still the most cost-effective strategy for tuberculosis control, there is an urgent need for an improved vaccine. Current BCG vaccine lacks efficacy in preventing adult pulmonary tuberculosis, the most prevalent form of the disease. Targeting nasal mucosa, Mycobacterium tuberculosis infection site, will allow a simpler, less prone to risk of infection and more effective immunization...
In this work, we decompose an input video clip into multiple smaller intervals, measure the quality of each interval separately, and apply a fusion approach to integrating these scores into a final one. To give more details, an input video clip is first decomposed into smaller units along the temporal domain, called the temporal decomposition units (TDUs). Next, for each TDU that consists of a small...
