GIS最基本功能：源码实现矢量数据（dxf格式）和栅格数据（dem格式）的打开。

这是一些关于openGL的示例代码，适合初学者使用，里面有很多个源程序和EXE程序，方便你查看

二维图形中扫描线填充算法，本程序根据鼠标左键选择图形每个顶点，用右键闭合图形，然后填充-2D scanning fill algorithm, the procedures under the left mouse button to choose graphics for each vertex, right-Closed graphics, then filled

pwinDOS下仿WIN3.2-pwinDOS under fake WIN3.2

利用小波双线性超分辨率重建算法得到的重建图像会出现低、高频系数不匹配的现象，从而使得到的高分辨率图像灰度偏移。本文对该方法进行了改进，并引入局部适应插值得到更为理想的重建算法。即小波与局部适应插值结合算法。-Using Wavelet bilinear super-resolution reconstruction algorithm is the reconstructed image will appear low, high-frequency coefficients does not match the phenomenon, thereby enabling high-resolution image to be offset. In this paper, the method is improved, and the introduction of local interpolation to be better adapted to the reconstruction algorithm. That is, wavelet interpolation combined with the local adaptation algorithm.

检测圆形目标的程序，可以在大面积的图象中检测出多个圆形目标-Circular target detection process, you can image a large area detected in more than a circular target

上面是实现后的界面展示，内含有维纳滤波，逆滤波，图像模糊，清晰化等处理的源代码

对图像进行逐点计算，并且取最大值和最小值的差值作为该点新的灰度值。 在区别边缘点和非边缘点时，首先确定一个阈值T，若图像中像素点的新 值大于该门限值，则可以初步确定为边缘点，小于T的新值被判断为非边缘点.-Image point by point basis, and taking the maximum and minimum points of difference as the new gray value. Edge in the difference between point and non-edge point, first determine a threshold T, if the image of the new pixel value is greater than the threshold, you can initially identified as the edge point, the new value is less than T have been judged as non-edge point.
