In this paper, a method is described to automatically estimate the visible body region of a computed tomography (CT) volume image. In order to quantify the body region, a body coordinate (BC) axis is used that runs in longitudinal direction. Its origin and unit length are patient-specific and depend on anatomical landmarks. The body region of a test volume is estimated by registering it only al...

We apply the technique of far-field interferometry to measure the properties of surface waves generated by two-dimensional (2D) single subwavelength slit-groove structures on gold films. The effective surface index of refraction n(surf) measured for the surface wave propagating over a distance of more than 12 mum is determined to be n(surf) = 1.016+/-0.004, to within experimental uncertainty cl...

Recently, the techniques of face recognition have been widely used in security application such as security monitoring, and access control. However, there are still some problems in face recognition system in which the light changes, expression changes, head movements and accessory occlusion are the main issues. In this article, a robust face recognition scheme is proposed. Speeded-Up Robust Fe...

The SenseCam is a wearable camera that automatically takes photos of the wearer’s activities, generating thousands of images per day. Automatically organising these images for efficient search and retrieval is a challenging task, but can be simplified by providing semantic information with each photo, such as the wearer’s location during capture time. We propose a method for automatically deter...

[1] Synchronous infrasonic, video, and wave height measurements were performed during high surf at Polihale beach, Kauai, on March 4–12, 2005. During the experiment, atmospheric sound levels in the 0.5–20 Hz frequency band were associated with large breaking ocean waves. The envelope of surf infrasound signals yields breaking wave periods comparable to those derived from nearshore sea surface e...

This paper introduces an optimised method for extracting natural landmarks to improve localisation during RoboCup soccer matches. The method uses modified 1D SURF features extracted from pixels on the robot’s horizon. Consistent with the original SURF algorithm, the extracted features are robust to lighting changes, scale changes, and small changes in viewing angle or to the scene itself. Furth...

Growth of videos in today’s Internet usage is extensive. Different types of videos will be available in the Internet which among them are lecture videos. Students can make use of these videos, so there is a need to develop an automated system to search the required content only, rather than wasting the time in viewing the complete video. This can be developed into automated system, required ste...

Local feature matching has become a commonly used method to compare images. For mobile robots, a reliable method for comparing images can constitute a key component for localization and loop closing tasks. In this paper, we address the issues of outdoor appearance-based topological localization for a mobile robot over time. Our data sets, each consisting of a large number of panoramic images, h...

In open-access settings, high-quality resources are lucrative, yet fencing out potential entrants may be very costly. I examine the endogenous creation of property rights, focusing on the incentives that resource quality provides to close the commons. Analytical examples explore the incentives of locals to increase or decrease the strength of property rights conditional on how locals and nonloc...

Content-Based Image Retrieval (CBIR) is a challenging task which retrieves the similar images from the large database. Most of the CBIR system uses the low-level features such as colour, texture and shape to extract the features from the images. In Recent years the Interest points are used to extract the most similar images with different view point and different transformations. In this paper ...
