Imaging a rectangular fluidised bed by electrical capacitance tomography: preliminary results

Wei Wang; Hairui Yang

2011 Sensor Review

doi:10.1108/02602281111169721

Purpose – Rectangular fluidised beds are commonly used in industry, e.g. circulating fluidised bed (CFB) boilers. Apparently, no one has tried to imagine rectangular fluidised beds by electrical capacitance tomography (ECT). The purpose of this paper is to design a rectangular ECT sensor to...

A fast and effective approach to generate true orthophoto in built‐up area

Cheng Zhong; Hui Li; Xianfeng Huang

2011 Sensor Review

doi:10.1108/02602281111169758

Purpose – Orthophoto suffers from the relief displacement effects magnified by high resolution imaging sensors especially when mapping urban areas. True orthophotos eliminating relief displacement with digital surface model (DSM) are presented to assure reliable interpretability and maintain the...

Robust watermarking in wavelet domain based on chaotic scrambling

Yanling Wang

2011 Sensor Review

doi:10.1108/02602281111169767

Purpose – The purpose of this paper is to present an imperceptible and robust watermarking algorithm with high embedding capacity for digital images based on discrete wavelet transform (DWT) domain. Design/methodology/approach – First, the watermark image is scrambled using chaotic sequence and...

In‐plane displacement sensing from circular grating moiré fringes using graphical analysis approach

Kin Yen; Mani Ratnam

2011 Sensor Review

doi:10.1108/02602281111169776

Purpose – Researchers in the past have used Fourier transformation method to determine the in‐plane displacement components from moiré fringes generated by a pair of overlapping circular gratings. In this approach it is necessary to assume that the transmittance is sinusoidal. The purpose of this...
