To carry out statistical validation of a newly developed magnetic resonance imaging (MRI) auto-contouring software tool for gross tumour volume (GTV) delineation in head and neck tumours to assist in radiotherapy planning.Axial MRI baseline scans were obtained for 10 oropharyngeal and laryngeal cancer patients. GTV was present on 102 axial slices and auto-contoured using the modified fuzzy c-means...
A combined interpolation – three-dimensional level set method (3D LSM)-based segmentation process is presented. The performance in terms of accuracy of the 3D LSM in the segmentation of throat regions from highly anisotropic magnetic resonance imaging (MRI) volumes, with and without an interpolation step is evaluated. Qualitative and quantitative results from real MRI data suggest that performing...
Electromyography is the study of the voltage polarisation signals generated during body muscle contractions. Surface EMG is non-invasive and is ideal for applications such as training, rehabilitation and active prosthesis control. Despite the progress in technology, myoelectric prostheses currently on the market still adopt simple analog sensors. Digital EMG acquisition is now common practice in research...
The improved mean shift (IMS) algorithm can effectively track a colour target undergoing fast motion and complete occlusion. Instead template matching based on the sum of weighted absolute differences (SWAD) can track a target precisely, even under partial occlusion. To take advantage of both trackers, this paper presents a novel tracking algorithm that, on one side, further improves the IMS and extends...
Support Vector Machine (SVM) is a very powerful tool for signal prediction including classification and regression. With Texas Instruments TMS320C6713 DSK, an embedded SVM is implemented, where a user friendly interface is provided via peripherals like the DIPs and LEDs. The C6713 processor in combination with the SDRAM block memory can solve the complex computation that SVM requires. Also a Real-Time...
The new generation of 3D imaging sensors allows to go beyond the traditional 2D object detection. In this paper a low-cost robotic platform exploiting the sensing capabilities of the Microsoft Kinect is presented. The developed mobile vision system is called RoboKinect and it utilises affordable hardware components such as the Texas Instruments OMAP-based BeagleBoard and the MSP430 microcontroller,...
In this paper, we describe a smart surveillance system to detect human faces in stereo images with applications to advanced video surveillance systems. The system utilizes two smart IP cameras to obtain the position and location of the object that is a human face. The position and location of the object are extracted from two IP cameras and subsequently transmitted to a Pan-Tilt-Zoom (PTZ) camera,...
With the advent in display technology, the 3DTV will provide a new viewing experience without the need of wearing special glasses to watch the 3D scenes. One of the key elements in 3DTV is the multi-view video coding, obtained from a set of synchronized cameras, capture the same scene from different view points. The video streams are synchronized and subsequently used to exploit the redundancy contained...
