Description: 在绝大多数的Windows应用程序中，其窗体都是使用的正规正矩的矩形窗体,例如我们常用的，“记事本”，“扫雷”，等等。矩形窗体，具有编程实现简单，风格简洁的优点，所以在普通文档应用程序和 简单小游戏中使用足矣。但在某些娱乐游戏程序中使用就略显呆板些了，这时若用不规则窗体替代原先 的矩形窗体，将会使这类程序更添情趣。典型的例子有windows 自代的Media Player,新版本的Media Player有个控制面板的选项，选中这些面板，播放器就以选中的面板形状出现，这时的播放器比以前版 本的Media Player的古老矩形界面要生动有趣的多了。 要实现不规则窗体不是太难，知道了基本原理后，你也可以创建各种有趣的不规则窗体。-in most Windows applications, all of its forms is the use of the formal moments of rectangular windows, for example, we used, "Notepad", "mine" and so on.

But in some amusement games procedures on the use of a slightly more rigid, then using the irregular forms of alternative original rectangular windows, such procedures will be added with more amenities.

the p rincipal components analysis, itwas shown that the p rincipal components analysis (PCA) could be app lied in dimension
reduction of image Zernike moments feature. Meanwhile, the p rocess of the dimension reduction based on PCA was put
forward. The experimental results demonstrate the feasibility of the app lication.

Description: A new approach for fingerprint verification, based on wavelets and pseudo Zernike moments (PZMs), is
discussed. PZMs are robust to noisy images, invariant to rotation and have a good image reconstruction
capability [4]. PZMs have been used for global analysis and so they are used to extract global features (the
shape of the fingerprint image). Wavelets are good at local analysis and so they help to extract local
features (minutiae) from a fingerprint. Therefore, this hybrid approach extracts most significant features
from the fingerprint images and achieve better verification rate. Different types of wavelets are used for the
study but the result shows that Symmlet orthonormal wavelet of order 8 gives best verification rate.

Description: shape of an image :
Shape factors are dimensionless quantities used in image analysis and microscopy that numerically describe the shape of a particle, independent of its size. Shape factors are calculated measured dimensions, such as diameter, chord lengths, area, perimeter, centroid, moments, etc.
