Rapid changes have occurred in the world economy during recent years, and organisations are concentrating on the move towards e -Business and e -Commerce. The paper follows a logical approach firstly identifying the business benefits of eEnterprises such as increased market share, improved customer services, and improved supply chain management. Critical success factors t hat an organisation ne...

The reliable object invocation mechanism provided by HIDRA for the coordinator-cohort and the passive replication models offers support to ensure that all the replicas of the object being invoked are correctly updated before such an invocation is terminated. This mechanism also ensures that if a primary or coordinator replica crashes, the client is able to reconnect to the previously initiated ...

Dynamic scintigraphic images allow functional exploration of the considered organ and thus a good comprehension of the pathological phenomenon. There are two different approaches to analyse such images series; by following the activity of a region of interest or by computing parametric images. Both approaches may require the detection of an area of interest. This paper presents two methods of a...

It is essential to have a reliable system to detect humans in close range of forestry machines to stop cutting or carrying operations to prohibit any harm to humans. Due to the lighting conditions and high occlusion from the vegetation, human detection using RGB cameras is difficult. This paper introduces two human detection methods in forestry environments using a thermal camera; one shape-dep...

Techniques for navigating through and retrieving text documents are widely understood and there any many tools that support their use. By contrast the extension to non-text information such as image, video, and sound is not widely supported at all. This is due to the fact that the fundamental operations of selection and matching are not as well de ned as they are for text. Unlike textual media ...

Image segmentation is a mechanism used to divide an image into multiple segments. It will make image smooth and easy to evaluate. Segmentation process also helps to find region of interest in a particular image. The main goal is to make image more simple and meaningful. Existing segmentation techniques can’t satisfy all type of images. This survey addressed various image segmentation techniques...

Kurzfassung. Methods to evaluate migration capacity of stem cells and the inhibition by chemicals are important for biomedical research. Here, we established an automated image processing framework to quantify migration of human neural crest (NC) cells into an initially empty, circular region of interest (ROI). The ROI is partially filled during the experiment by migrating cells. Based on an im...

We propose a method of hand waving gesture detection using a far-infrared sensor array. The far-infrared sensor array captures the spatial distribution of temperature as a thermal image by detecting far-infrared waves emitted from heat sources. The advantage of the sensor is that it can capture human position and movement while protecting the privacy of the target individual. In addition, it wo...

Theory of mind (‘ToM’) tasks elicit highly reliable neural activity across individuals and experimental paradigms. We compared activity in a very large sample of neurotypical (‘NT’, N=477) individuals, and a group of high functioning individuals with autism spectrum disorders (‘ASD’, n=27), using both region of interest (‘ROI’) and whole-brain analyses. Although ToM activity showed significant ...

A multi-threshold level set model for image segmentations is presented in the paper. The multi-threshold level set formulation uses a speed function for stopping the locations of the active contours. The speed function with multiple thresholds is designed for detecting boundaries of multiple regions of interest (ROI) in images. These thresholds can be automatically obtained by Fuzzy C-means met...
