From TEM bright field image, it can be seen that the surface image of CoPt formed discrete islands, and gradually change to continuous film as the CoPt thickness increase. After annealed at 700℃ for 30 minutes, the single domain state is found by the observation of MFM images at 7.5 nm CoPt. At single domain state, the variation of coercivity with particle size agree with the theory of single domain particles.

It can get the three-dimensional profile of the object surface effectively. Because of the cragginess of the three-dimensional surface when sine grating is projected the image of the sine grating is modulated and the modulated image is taken by a CCD camera with an angel compared to projecting direction. After the phase shift measuring method, the phase is gotten. Because the phase is calculated by the phase shift measuring ranges from –π to +π it isn't continuous. The phase unwrapping is necessary to recover the continuous phase about the object shape.

In this paper, a speckle reduction method for SAR images based on Dual Tree Complex Wavelet Transform is proposed. It first presumes the probability distribution function for complex wavelet coefficients of the original nature image, and then applies MAP theory to estimate coefficients from the noisy wavelet coefficients. Filtered image can be derived after inversed DTCWT.

After analyzing the characteristic of the rigid plane motion and the shortcomings of classical digital image correlation algorithms, the phase-angle position of the rigid body in the 2D image was characterized by 1D sequence signals using the method of equiangular sampling feature extraction based on circle windows. Then the generalized correlation algorithm for estimation of time delay based on wavelet transform was used to acquire the angular displacement. Finally the ultrasonic radiation force acted on the micro-component was determined by the relation between force and motion.

Two pairs of vanishing points of orthogonal directions from each image are obtained by using the concept of cross ratio and harmonic conjugate in projective geometry and the orthogonal property of the two diagonals on a square. All intrinsic parameters are calculated linearly after capturing the template from at least three shooting angles. Errors of edge detection and line fitting are avoided because the method does not require image matching.

First of all , it is seen in Zhang Wei"s long writing that continuous changes occurs with the following era contexts which is shown. First, the gradual desalinization of " earth image " on the space," earth " is not only a creation in Zhang Wei"s novel, but the main source of the poesy of its works. It declines after " September fable ", not only indicating Zhang Wei "s decay of poesy of the novel, but also reflecting the disobeyed pross of light appear contemporary China social urbanization and common customs to . Second, the change of " writing subject projection " in the spiritual meaning, Its characteristic displayed by the reduction of image of spokesman as write thought representation .and on the other side represent" person who want more that resist actively " which also shows contemporary intellectual predicament and adjustment of value. Third, in " changeable and separate characteristics in the stylistics ",It changes " epic body " of" Ancient ship "," body not mythical " to " September fable "," pour out body " of" Bai Hui "" Family "," the discipline spreads the body "of Book of other provinces"," lie body " of" Can not recall the hollyhock ". Its constant changes persuing of recreation and sports, has entered into the different book mode and narration of different class gradually too.
