medianfiltering

数字水印源码，基于matlab的，可实现，共同分享。(Digital watermarking source code, based on the matlab can be realized.)

这个函数得到一个形象的名字，应该是RGB，加载它并创建一个。与透明色的RGB图像的PNG地方是白色的。 如果第三个参数是setted黑色的非透明区域的功能将颜色(This functions gets an image name which should be RGB, load it and create a .png with transparent color where the RGB image is white. If the third parameter is setted the function will color in black the non-transparent areas)

本程序生成的图片容量大概3M左右，所以对计算机配置要求较高。(This program generates pictures capacity probably about 3M, so the higher the computer configuration requirements.)

matlab中数字图像处理程序，包含滤波，卷积，膨胀闭合等操作。(digital image process procedure in matlab, including filtering , convolution, swelling and closing.)

利用基于排序的邻域粗糙集算法对具有高维属性的元数据进行属性约简，删减多余的无关属性，避免模型的过拟合，提高模型预测精度和模型运算速度(The algorithm based on the ordered neighborhood rough set is used to reduce the attributes of the high dimension attributes, to eliminate the redundant irrelevant attributes, to avoid the over fitting of the model, and to improve the accuracy of the model prediction and the operation speed of the model)
