图像处理功能，包括滤波，各种边缘检测！ SOBEL,CANNY算子

自动获取最佳阈值，提取边缘。因为是根据我的项目编的，用时根据实际情况修改一下。-Automatically obtain the best possible threshold, the edge extraction. Because it is based on my items, and used according to the actual situation changed a bit.

Lee滤波,实现相干斑点去噪算法,在SAR图像去噪中应用广泛-Lee filtering to achieve speckle denoising algorithm, the SAR image denoising widely used

图像处理中，可以显示图像，并对图像进行操作处理，形态变换等，是图形图像处理有用的一个程序-image processing, can show images and image processing operation, morphological transformation. Graphic Image processing is a useful procedure

BMP图像转灰度图像，在图像处理中非常有用！-BMP image to gray-scale images, in image processing is very useful!

本代码实现的功能：24位位图（BMP）的灰度化。具体实现过程：打开图像文件,找到数据区(每3个字节代表一个象素的R,G,B值),循环扫描,根据RGB的权重,计算出灰度值. 如果要得到256色灰度图,则要新建一个调色板,修改信息头和文件头.-Realize the function of the code: 24-bit bitmap (BMP) of the gray. Concrete realization of the process: Open the image file, locate the data area (3 bytes per pixel on behalf of a R, G, B values), cyclic scan, according to the weight of RGB, gray value is calculated. If you want to get 256 colors grayscale, would create a new palette, modify the header and file header information.

JPEG图像压缩与BMP位图的比较。JEPG的实现源码。-JPEG image compression and BMP bitmap comparison. JEPG the realization of the source code.

各种直方图的求法。可以求取并显示各种直方图。-All kinds of Histimage .

判断点是否在多边形中，输入要求有组成多边形的点和要判断是否在多边形中的点，速度快！-To determine whether the polygon points, enter the required polygon composed of points and to determine whether the points in the polygon, fast!

实现在YUV图像上面按照算法叠加OSD信息-Achieve the YUV overlay the image above, OSD information in accordance with Algorithm
