The curvelet transform is a new multi-scale analysis method which can be used to represent perfectly the curve edges of natural image. Robust image watermark algorithm should embed the watermark into the edges of image according to human visual system. In this paper, an adaptive image watermark algorithm in curvelet domain was proposed. Firstly, the original image was decomposed into curvelet coefficients...
In this paper, a parameter design of the 4-band symmetric low-pass filters with short support is given and the corresponding scaling functions are constructed. At the same time, we use these 4-band wavelet filters in this paper to do image fusion with new fusion rules which we proposed. Finally, we compared the results of image fusion using 4 band wavelet filters with the results of image fusion using...
With the voltage decreasing in power distribution network (PDN) in system-on-packages (SOPs), power integrity will be a critical issue. The cavity resonance modes between power and ground planes can be excited by simultaneous switching noise (SSN) or ground bounce noise (GBN) [1], [2]. To cut down the noise from susceptible devices, isolation techniques are necessary. In this paper, two novel structures...
