特征向量

Information of transform watershed

说明：  对图像进行小波分解后，并抽取出分解后的垂直高频分量，并将其保存出来。(Image after wavelet decomposition, and to take out after the decomposition of the vertical high-frequency component, and save it out.)

1、可制作圆形、椭圆形、菱形、方形、三角形印章。 2、支持多种特效：翻转图形、透明处理、高斯模糊、亮度/对比度/饱和度/锐化/反相/海绵/陨化(磨砂)/浮雕等等。 3、可将制作好的印章保存至印章库。 4、支持1％－1000％比例缩放。 5、支持导出印章图片(透明图章使用GIF格式)。 6、支持预览/打印。(1, can be made round, oval, diamond, square, triangular seal. 2, supports a wide range of effects: flip graphics, transparent deal, Gaussian blur, brightness/contrast/Saturation/Sharpness/RP/sponge/meteorite of (Matte)/relief and so on. 3, can be saved to create a good seal of the Treasury seal. 4, in support of 1-1000 scaling. 5, support for export seal picture (stamp the use of transparent GIF format). 6, support for preview/print.)

说明：  sar成像算法：RD、CS算法，希望对需要的人有用(sar imaging algorithm: RD, CS algorithm, and they hope to those who need it useful)

Opencv处理图像，用ostu法实现图像的二值化(Opencv image processing, using ostu method to achieve image binarization)

运行程序，得到不同伽马因子给图像的整体明暗程度带来的变化(Run the program to get the change of the overall brightness of the image with different gamma factors)

说明：  图像分块的处理和matlab水印的提取，(Image sub-block processing and matlab watermark extraction,)

利用opencv库写的一个关于图像孔洞填补的小程序，附加了效果图片(Using the opencv library to write a small program on the filling of the hole, the additional effect of the picture)

图像着色处理，对于不同亮度的图像显示不同颜色，应用于水下声纳图像效果比较好。(Image color processing, to the image shows different colors of different brightness, applied to the underwater sonar image effect is better. )

说明：  基于MATLAB的条形码识别。带GUI可视化用户操作界面。读取条形码，经过一系列预处理，如灰度化，去噪，直方图增强，中值滤波，二值化，腐蚀，识别等。可识别20多张条形码图片，另外可定制二维码的识别，二维码可自定义生成内容，生成二维码，然后嵌入数字水印进行加密传输，接收方提取水印的二维码，识别。(Bar code recognition based on MATLAB. Visual user interface with GUI. Read bar code, after a series of preprocessing, such as graying, denoising, histogram enhancement, median filtering, binarization, corrosion, recognition and so on. It can identify more than 20 bar code images, and can customize the identification of two-dimensional code. The two-dimensional code can generate the content of the two-dimensional code, generate the two-dimensional code, and then embed the digital watermark for encryption transmission. The receiver can extract the two-dimensional code of the watermark for identification.)
