Conference Paper
This work focuses on the further reduction of the bandwidth usage of the Bloom Filter based SNMP by means of an additional compression scheme. The zip compression technique is used for the zip encryption and the zip decryption of the Bloom Filter. The experiment with compression ratio was done and the results show that the SNMP bandwidth that utili...
Conference Paper
The hydrological observation data is important for hydraulic engineers. They have to use the obtained information to control quality or quantity of water in the river system. Nowadays plenty of hydrological information systems are available. However there are many difficulties to do the parallel accesses between those services, for example, they no...
Conference Paper
In this study, we aim at studying for an inexpensive-but-effective real-time localization and identification of known buildings or large permanent structures within user's current position in outdoor environment using integrated GPS and camera on smartphone. In addition to this, we also provide users guidance by augmenting text information describi...
Conference Paper
The growth of medical tourism in Thailand attracted many organizations to develop applications for assisting traveler information. However, these applications may not satisfy all traveler's requirements in term of medical, tourism and social network. In consequence, this study has been proposed a new prototype of the mobile social network applicati...
Article
This work proposed a real-time 3D map building system based on the visual odometry information derived from a Multi-Camera hardware. The accurate odometry information and images derived from the proposed intuitive Multi-Camera hardware, so called Multi-Camera Unit (MCU), are used as an input for the 3D map building process which cooperates the Fast...
Article
To measure service provider's local network performance has to use specific equipment and expert system which is too expensive for service provider to install all over the country. The active measurement system use only active monitoring techniques to measure quality of network and expert system use only passive monitoring techniques to analyze pro...
Conference Paper
This work proposed an improvement for the visual odometry based on a new hardware design concept. Generally, a visual odometry system relies on one stereo camera to detect the 3D features which are used as input for the ego motion estimation process. However, such design usually faced with the motion ambiguity problem resulting in poor estimation o...
Conference Paper
Motion estimation is one of the most important tasks for autonomous mobile robots. Modern mobile robots are equipped with different types of visual sensors that can provide wide ranges of outputs which can be used as reliable inputs for the computing of the robots displacement. One of the widely used visual sensors on mobile robots is the stereo ca...
Article
This paper introduces an improvement to the 6D motion estimation solution by combining the Photonic Mixer Device (PMD) and Stereo Camera. The main feature of the stereo camera is the higher resolution of the 2D image compared to the one from the PMD camera. Whereas the depth information derived from a PMD is usually far superior to the result from...
Conference Paper
This work proposes a multiple stereo cameras setup as sensing device for real time photorealistic 3D map building task. Applications include 3D photorealistic capturing of historic sites, remote exploration and navigation for autonomous robots, 3DTV, entertainment industry and much more. Particular emphasis is placed on the novel multiple cameras a...
Conference Paper
This paper describes a system for detection and classification of moving objects based on support vector machines (SVM) and using 3D data. Two kinds of camera systems are used to provide the classification system with 3D range images: time-of-flight (TOF) camera and stereo vision system. While the former uses the modulated infrared lighting source...
