This code is used for creating an initial structure made of either substrate atoms or deposited atoms. It generates three types of structures: rows, columns, and hemispheres. Type, size and number of objects are determined by the user. The  соde generates two files: ibox.txt and iboxXY_jmol.txt. The file ibox.txt contains coordinates of atoms in “integer” format (i, j, k, name_of_atom) and may be used as input to NASCAM. The file iboxXY_jmol.txt stores the same information about the position of the atoms but in Cartesian coordinates (name_of_atom x, y, z, ) in JMOL format. It may be used for visualization.     If a surface structure made of  atoms of both types is needed, then create two files, one for each type of atom, and then combine these files.

图像水印部分显示阿须数码在数字图像上的数字水印技术。在不改变原有图像品质的情况下将数字水印信息隐藏于图像本身,并可在需要时能提取，用以作为版权声明和信息保护等。-watermark images shown in part aXu in digital image on the digital watermark technology. Without changing the original image quality of the digital watermark information hidden in their own images, when they need it can be extracted and used as a copyright notice and information protection.

 Harris Corner是最典型的角点检测子Corner Detector。角点经常被检测在边缘的交界处、被遮挡的边缘、纹理性很强的部分。满足这些条件一般都是稳定的、重复性比较高的点，所以实际上他们是不是角点并不重要（因为我们的目标就是找一些稳定、重复性高的点以作为特征点）。

canny检测器是很有效的边缘检测器，该函数可以实现对目标图像的边缘提取。该方法总结如下：1.图像使用带有指定标准差的高斯滤波器来平滑，以此减少噪声；2.在每一点计算局部梯度和边缘方向；3.第二步中确定的边缘点会导致梯度幅度图像中出现脊，然后追踪所有脊的顶部，并将所有不再脊顶部的像素设置为0；4.执行边缘链接-canny detector is very effective edge detector, this function can be achieved on the target image edge detection. This method is summarized as follows: 1. Image used with the specified standard deviation of the Gaussian filter to smooth out, thereby reducing the noise 2. In the calculation of each point of local gradient and edge direction 3. The second step in determining the edge points will led to the image gradient magnitude ridge appears, and then keep track of all of the top of the ridge, and ridge at the top of all the pixels are no longer set to 0 4. the implementation of the edge link
