Intelligent Sensor Networks

Preface

Nowadays, various sensors are used to collect the data of our environment, including RFID, video cameras, pressure, acoustic, etc. A typical sensor converts the physical energy of the object under examination into electrical signals to deduce the information of interest. Intelligent sensing technology utilizes proper prior knowledge and machine learning techniques to enhance the process of information acquisition. Therefore, the whole sensing procedure can be performed at three levels: data, information, and knowledge. At the data level, each sample represents a measure of target energy within a certain temporal-spatial volume. For example, the pixel value of a video camera represents the number of photons emitted within a certain ...
