A novel multi-view 3D face registration method based on principal axis analysis and lab.led regions orientation called local orientation registration is *** pre-registration is achieved by transforming the multi-pose models to the standard frontal model＇s reference frame using the principal axis analysis *** significant feature regions, such as inner and outer canthus, nose tip vertices, are then located by using geometrical distribution *** regions are subsequently employed to compute the conversion parameters using the improved iterative closest point algorithm, and the optimal parameters are applied to complete the final *** results implemented on the proper database demonstrate that the proposed method significantly outperforms others by achieving 1.249 and 1.910 mean root-mean-square measure with slight and large view variation models, respectively.
A new image encryption algorithm is proposed in the paper. Its essential idea is that, firstly, we produce a knight's tour matrix emended as slip encryption-filter template matrix;And then, we produce a knight'...

“Signal Conditioning” is a comprehensive introduction to electronic signal processing. The book presents the mathematical basics including the implications of various transformed domain representations in signal synthesis and analysis in an understandable and lucid fashion and illustrates the theory through many applications and examples from communication systems. The ease to learn is supported by well-chosen exercises which give readers the flavor of the subject. Supplementary electronic material is availab.e on http://*** including MATlab.codes illuminating applications in the domain of one dimensional electrical signal processing, imageprocessing, and speech processing. The book is an introduction for students with a basic understanding in engineering or natural sciences.
This paper proposes a new approach for interpolating natural images. Unlike other conventional interpolation methods, we exploit the characteristics of an image and decompose it into a texture part and a non-texture (...

The preferred green grass and red(apple, lipstick, sports car) colors shown on the display are investigated using two different image sizes i.e. 2.4" and 7.7". Ten test images were used in the experiment and each image was transformed using memory color transformation algorithm to have different nine green grass or red colors. The pair comparison method was used to find out the most preferred green grass and red colors. It is found that there is little preference change by the image size change. The green grass colors are preferred as the average hue angle becomes closer to 130 degree (65% green and 35% yellow) in CIECAM02 hue angle with high chroma. In the case of red colors, apple images shows the high preference when the reproduced red is closer to the unique red (20.14 degree). The artificial objects such as red lipsticks and sports cars are preferred when reproduced with highest chroma regardless their hues. Copyright 2006 Society for Imaging Science and Technology.
In this paper, a new approach is presented for single-channel speech enhancement which is based on Nonnegative Matrix Factorization (NMF). The proposed scheme combines the noise Power Spectral Density (PSD) estimation...
