The aims this paper is to display the apriori data mining method results implanted in SINPE?? (Electronic Protocols Integrated System) in an Enteral Nutrition research. We developed the data mining in the SINPE and later the items body mass index (BMI or IMC) and Enteral diet were selected from the database of the Homecare Enteral Nutrition Research. The parameters used were 10% support and 50% confidence...
Security in Wireless Sensor Networks (WSNs) is especially challenging and quite different from traditional network security mechanisms. There are two major reasons. Firstly, there are severe constraints on these devices namely their minimal energy, computational and communicational capabilities. Secondly, there is an additional risk of physical attacks such as node capture and tampering. Moreover,...
In this paper, a new image compression scheme by introducing visual patterns to interpolative vector quantization (IVQ) is proposed. The goal is to introduce visual patterns on designing the codebook, where only removed details that contain visual patterns and their original counterparts as pairs are trained. In the proposed scheme first input images are down-sampled by ideal filter. Then, the down...
Completely automated public turing tests to tell computers and humans apart (CAPTCHAs) are the automatic filters that are widely used these days to disallow any automated script that can perform the work of a human. CAPTCHAs are built in such a way that it is very difficult for any automated script to break them. In this paper, an approach to break text based CAPTCHAs has been proposed that first...
The augmented k-ary n-cube AQn,k is a recently proposed interconnection network that incorporates an extension of a k-ary n-cube Qnk inspired by the extension of a hypercube Qn to the augmented hypercube AQn (as developed by Choudom and Sunita). We extend a recent topological investigation of augmented k-ary n-cubes by proving that any augmented k-ary n-cube AQn,k is edge-pancyclic and that AQ2,k...
Group awareness information is important information for group work. It represents things such as group members' roles and responsibilities, their positions on an issue, their status, and the state of various group processes that group members know about when they work together. The group awareness information presented in this article is designed to capture group member activities and their behaviors...
Here an efficient fusion technique for automatic face recognition has been presented. Fusion of visual and thermal images has been done to take the advantages of thermal images as well as visual images. By employing fusion a new image can be obtained, which provides the most detailed, reliable, and discriminating information. In this method fused images are generated using visual and thermal face...
Topological maps are used by biological species for navigation in complex and cluttered environments with very primitive sensory inputs and limited computational abilities. The core aspect of topological maps are the properties (usually some environmental features) used to define the nodes of the map. In this paper we use a well known technique adopted by desert ants called visual piloting for autonomous...
It is well known that the human visual system (HVS) cannot sense all changes in an image/video due to its underlying physiological and psychological mechanisms. We propose a complete masking estimation model for image/video in this paper. In our model, a very important mechanism of the HVS, visual attention, is incorporated to the existing just noticeable difference (JND) estimation models. A formula...
In chemoembolization, chemotherapy drugs and thrombotic agents are directly injected into the liver tumor through a catheter navigated to the artery that supplies the tumor. In order to help surgeons to train their hand-eye coordination skills to reduce the risk of injecting the thrombotic agents incorrectly and deprive normal tissue of its blood supply, this paper proposes a method for rendering...
Vestibular dysfunction is associated with the developmental delay of motor and attention skills. Integrity of the vestibular and visual systems manifest in rapid side to side eye movement called nystagmus. This may be evoked by physical rotation or caloric stimulation to the ear drums. The approach in this technological advance explores whether controlled rotation of the environment can induce the...
We consider a problem about navigation of a mobile robot with a camera in indoor environment. A new visual control method using a vanishing point of parallel lines at both sides of the corridor is introduced, and we call this the vanishing point visual control method. This method gives a lot of useful information on the design. Therefore we can't need a priori information except both widths of the...
In the last few years the eLearning environments have known a very accelerated development becoming a very important educational alternative to the classical teaching methods. Together with the global extend of the Internet infrastructure, the multimedia elements have been more and more used as learning objects providing new methods of information presentation and user interaction techniques. One...
Minimally invasive surgery offers advantages that make it the best choice for many diseases. Modern technologies give a great support to this kind of surgical procedures through medical image processing and visualization, 3D organ's reconstruction and intra-operative surgical guidance. In this paper is presented an advanced visualization and navigation system and the surgeon has the possibility to...
With the increase of the number of the blind, demand for visual prosthesis is increasing. Text reading is one of the most important visual functions to the blind. Therefore human trials and simulations of prosthetic vision have already been carried out for testing an improved system or studying rehabilitation of people who implant prosthesis. But although forms of electrode arrays used in those studies...
When the traditional CANNY algorithm is applied for edge detection, thresholds are needed to filter candidate edge points after non-maximal suppression. But at present, thresholds are set by experience and the optimal choice is obtained by repeated tests and comparisons. In addition, the choice of current thresholds does not take characteristics of uneven lighting images into account. In some special...
Filmification of methods is a promising concept to find new formats for program and data/knowledge representation. It is also to create a basis for specifying and developing a new generation of programming environments, as well as for introducing new types of educational materials. Within this approach various algorithms are analyzed and represented as cyberFilms where special visual constructs, super-symbols...
This paper presents a projection model to fuse the scores of a visual face verification system and an infrared face verification system. Essentially, the model consists of an arbitrarily number of linear projection vectors with randomly permuted elements. An equal error rate formulation is next adopted to learn the linear coefficients for projection. The learned model is consequently used for prediction...
Although traditional line illustrations are very abstract representations, they can communicate the form of an object effectively. This is only possible by the use of perceptual cues, mastered by professional artists. To create effective line illustrations from 3D models, it is important to use these perceptual cues to avoid visual dissonance and ambiguity, and also to create visual effects like shading,...
The modeling of weathering effects in still images is a powerful editing tool for many graphics applications. Although most of these effects can be generated by manually creating textures through graphics editing applications, performing such artist work is time consuming. More sophisticated and automatic solutions to simulate a wide variety of weathering effects become essential. We present a method...
