The availability of datasets capturing the performance of activities of daily living is limited by difficulties associated with the collection of such data. Software solutions can mitigate these limitations, providing researchers with the ability to rapidly generate simulated data. This paper describes the use of IE Sim to create a simulated intelligent(More)
Since the ionizing radiation may induce cancers and genetic damages in the patient, it is highly desirable to minimize the X-ray dose during a CT scan. As one of the local imaging techniques, the Lambda imaging reduces the X-ray dose and imaging time. But the existence of the singular values results in the low quality of the image. The broad applications of(More)
This paper introduces WiiPD, an approach to home-based objective assessment of Parkinson's disease. WiiPD aims to make use of the many capabilities of the Nintendo Wii Remote in combination with a number of bespoke data gathering methods to provide a rich and engaging user experience that can capture a wide range of motor and non-motor metrics. In this(More)
This paper presents a new fragile watermarking scheme based on integral wavelet transform. The proposed method uses the quadtrees structures received by the wavelet decomposition, statistical information on the nodes and secret key to choose the locations where to embed the watermark. Only one bit watermark information will be hidden in the found position.(More)
Serial number is an important component to paper money. It is an important identifier to every piece of paper money. This paper presents an effective method on segmentation and recognition of RMB serial number. This methodology can be classified as three stages: preprocessing stage, Serial number segmentation stage and serial number recognition stage. The(More)
This paper outlines a tool for the visualization of data generated within Intelligent Environments. This tool has been designed with a focus on flexibility and customizability hence facilitating application to a range of areas including institutionalized or home-based healthcare monitoring. Through the use of an object toolbox, non-technical users can(More)
We propose an improved super-short-scan reconstruction algorithm for fan-beam computed tomography based on pi-lines in this paper. Within the framework of the classic FBP algorithm, this new algorithm can achieve exact reconstruction of the region of interest (ROI), if and only if all lines passing through the ROI intersect the source trajectory. The new(More)
