QMap - 锐化与平滑

 锐化与平滑都是图像处理的常用方法。由于我们采取了红绿蓝三通道分别处理的方法，所以，可得到更好的效果。同时，将锐化与平滑合并在一个单元内，便于操作。

现按软件功能界面介绍如下：

1. 锐化与平滑的选择
    默认时，选择“锐化”处理。有三种算法可供选择。选择“平滑”时，也有三种算法可供选择。
    选择不同的算法进行试验，以达到最佳的处理效果。

2. 红绿蓝通道选择
    默认时，红绿蓝通道均被选中。当通道未被选中时，如果“屏蔽未被通道”被选中，则该通道的颜色数据被置0，反之保持原状。“屏蔽未被通道”默认时未被选中。

3. 强度选择
    处理中通过增加“强度”系数，可以一次性加强或减弱效果。默认为1，可调节范围为（-20，20）。

4. 试验与处理
    在选定参数后，点击“试验”按钮快速查看效果，满意后点击“处理”按钮，完成处理。

QMap - Geodetic Control Point (GCP) Geometric fine correction

Image
The purpose of geometric correction is to map an image without geodetic coordinates to a given coordinate system. Through mapping transformation, it can eliminate the deviation of image geometric position caused by various factors, such as extrusion, stretching, distortion and offset, etc. It is especially suitable for remote sensing images and stitching of various super large images. Through geometric correction, precise positioning images of various geographic information can be established, which makes the analysis of historical changes with time as the axis very convenient. Now according to the software function interface, the introduction is as follows: 1. Load control point file     Click the "Load" button to load the selected geodetic control points with features. The control points to be selected are listed in the list box at the top of the dialog. 2. Match Control Points      Click an item in the list box at the top, and the details are listed in the ed...
