With the proliferation of multimedia information on the network, automatic rating of web pages becomes more and more
important for web management. Obviously image analysis is very important in these kinds of tasks. But to our best
knowledge, there are no publications reported on it. In this paper, we propose a novel framework to rate webpage using
image content analysis. The rated categories are in compliance with the standard utilized by most web browsers like
Internet Explorer, which include Normal, Revealing Attire, Exposed Breasts and Bare Buttocks. To make the rating work
feasible, we analyze the images mainly using skin detection and body region, and face detection is also used as guidance
for the detection of skin and body region. After that, all the results of image content analysis are integrated to achieve
content rating results for web pages. We tested our system on two data sets and demonstrated its effectiveness.
A cheap and simple method of depositing copper into porous silicon by cathode electroplating was described. The existence of cubic copper nano-particles (~30nm) into porous silicon matrix was verified by X-ray Diffraction and Scanning Electron Microscopy. The microcrystal size of porous silicon and strain between porous silicon and copper layer were discussed based on the Raman spectra.
Oxidized porous silicon/porous silicon (OPS/PS) has been introduced as a low-loss substrate for an on-chip LC low-pass filter (LPF). The LPF is optimally designed with midband insertion loss (MIL) of -4.5dB and nominal cutoff frequency at 900MHz. The fabrication of the LPF based OPS/PS is in prevailing CMOS process. Experiments show that the performance of the LPF has been greatly improved with MIL of -4.54dB that meets the designed value quite well. And in comparison with MIL of LPF on SiO<sub>2</sub>/Si (8Ω cm), MIL with the proposed interlayer is lowered by 8dB, which implies that the microwave loss resulting from the substrate part can be substantially suppressed by introducing OPS/PS.
Hydroxyapatite (HAP) nano-particles obtained by coprecipitate process are deposited on porous silicon substrates, after being annealed, HAP films connected tightly with porous silicon substrates. The resulted samples were investigated by XRD, AFM and SEM.
