Digital watermarking is widely believed to be a valid means discourage illicit distribution of information content. methods for text documents are limited because the binary nature documents. A distinct feature document its space patterning. We propose new approach in which interword spaces different lines slightly modified. After modification, average various have characteristics sine wave and constitutes mark. Both nonblind blind algorithms discussed. Preliminary experiments shown...
The effects of laser scanning speed on the microstructure, microhardness, and corrosion behavior Ni45 coatings were investigated by using optical microscopy (OM), electron (SEM), X-ray diffraction (XRD), electrochemical measurements. results showed that increasing promotes transformation from planar crystals to dendrites refines grains concurrently. γ -(Ni, Fe), FeNi 3 , M 23 (C,B) 6 are identified as primary phase composition in regardless speed. Thereinto, formation growth precipitates can...
This paper presented a new DCT-based watermarking algorithm for vector digital maps. A watermark bit is embedded by modifying the relationship of several high-frequency coefficients in DCT domain. To enhance data accuracy and robustness watermark, we proposed Double Error Estimation method. method allowed watermarks to be when vertices with distortion are smaller than thresholds. Experiments show that resilient random noise, general geometric transformation, scrambling cropping. The blind it...
Object tracking is one of the most important techniques in digital image processing. Considering weakness and shortage traditional moving target method, this paper designed realized a simple effective object method. At first, proposed pixel intensity classification single Gaussian model based background reconstruction algorithm. Then use subtraction method to extract foreground as initialization Finally, apply Kalman filter camshift algorithm track target, which combined with solve shadow...
To reduce the influences of vibration large erecting system in process erecting, this paper firstly built a simulation model, then an erect angle velocity was planned so that it can minimize at stage beginning, multi-stage cylinder changing and arriving, thus other stages be increased . Meanwhile fuzzy adaptive PID controller applied to track curve. Finally, validates shock are effectively reduced by method. Fast stable erection load is realized. Compared with original controller, proved...
This paper, as a pilot study of my PhD project, testifies and evaluates the application semi-automatic approach to identify formulaic sequences from Early Modern English texts. It also explores possibility classifying identified following an existing functional classification taxonomy designed by Conrad Biber (2005). The grouped lexical bundles in Present-Day conversation academic prose into four primary categories: stance expressions, discourse organisers, referential special conversational...
This paper proposes a novel skeleton extraction algorithm of Chinese characters in picture. In the algorithm, we extract strokes horizontal (vertical) firstly based on definitions. And then, get intersection points among stroke skeletons by extending contour line. Finally, thin other maximum inscribed rectangle discriminant and thinning algorithm. whole is extracted.
