Abstract. In this paper we present a novel approach for image description. The method is based on two well-known algorithms: edge detection and blob extraction. In the edge detection step we use the Canny detector. Our method provides a mathematical description of each object in the input image. On the output of the presented algorithm we obtain a histogram, which can be used in various fields of computer vision. In this paper we applied it in the content-based image retrieval system. The simulations proved the effectiveness of our method.

PROCHÁZKA, D., KOUBEK, T.: Augmented reality implementation methods in mainstream applications. Acta univ. agric. et silvic. Mendel. Brun., 2011, LIX, No. 4, pp. 257-266 Augmented reality has became an useful tool in many areas from space exploration to military applications. Although used theoretical principles are well known for almost a decade, the augmented reality is almost exclusively used in high budget solutions with a special hardware. However, in last few years we could see rising popularity of many projects focused on deployment of the augmented reality on diff erent mobile devices. Our article is aimed on developers who consider development of an augmented reality application for the mainstream market. Such developers will be forced to keep the application price, therefore also the development price, at reasonable level. Usage of existing image processing so ware library could bring a significant cut-down of the development costs. In the theoretical part of the article is presented an overview of the augmented reality application structure. Further, an approach for selection appropriate library as well as the review of the existing so ware libraries focused in this area is described. The last part of the article out lines our implementation of key parts of the augmented reality application using the OpenCV library.augmented reality, OpenCV, template matching, ARToolkit, computer vision, image processing.

Security and quality of service are two major problems in wireless communications. This work concentrated on improving the security levels for Enhanced Bio-cryptic Security-Aware Packet Scheduling-Algorithm (EBSPS) and also the fast communication between Wireless Node (WN) and Advanced Radius authentication server (ARAS). This paper introduces a novel Enhanced Merged Bio-cryptic Security-Aware Packet Scheduling-Algorithm (EMBSPS). Simulations were conducted using the Matlab and EMBSPS is compared with the results of present EBSPS and BSPS. To accomplish better Quality-of-Service (QoS) in WLAN, it is substituted with the existing EBSPS with novel EMBSPS. This EMBSPS Algorithm assures the finest concert in improving the security levels and speeds up the authentication process. Lastly, simulation result proves that proposed model is performing finer than the present algorithm in terms of the quality of service. General TermsWireless communications and Security
