Human action recognition has been extensively studied with a lot of real life application. Many methods have been proposed and achieved promising results when the input video captured from the same viewpoints. However, their accuracy decreases significantly under viewpoint changing. The reason is that action appearance is quite different when looking from a different angle. To overcome this problem,...
In this paper, we proposed a self-adaptive wireless indoor localization system for device diversity. The major feature is that our system can incrementally collect RSS data for device calibration without stopping the localization service. The system has two phases. In the localization phase, we used relative radio signal strength (RSS) features as inputs to overcome device diversity and train classifiers...
Recently, the techniques for indoor localization have become more and more important and play a critical role in many mobile applications. Among them, the fingerprint-based indoor localization system has been recognized as a possible right way toward success. However, some challenges still remain. One issue should be addressed is the device diversity problem, where different devices would receive...
In this paper, we proposed a region-based approach for indoor localization based on the fingerprint of radio signal strength (RSS). Unlike conventional fingerprint-based methods that based on point information to infer user's location, we used region information for indoor localization. Our results show that the proposed system has better positioning accuracy and more robustness to signal noise and...
The FPGA implementation of image registration algorithms is a challenging problem due to the limited resources of the hardware and the requirement for real-time processing speeds. Image registration approaches using low bit-resolution images are more feasible for implementation on FPGAs than those using full resolution images because of the significant reduction in hardware resources required. The...
Low blood glucose (Hypoglycaemia) is dangerous and can result in unconsciousness, seizures and even death. It has a common and serious side effect of insulin therapy in patients with diabetes. We measure physiological parameters (heart rate, corrected QT interval of the electrocardiogram (ECG) signal, change of heart rate, and the change of corrected QT interval) continuously to provide detection...
