中文说明： IDW距离反比加权方法，基于小波变换的数字水印算法matlab代码，采用的是通用的平面波展开法,DC-DC部分采用定功率单环控制，ldpc码的编解码实现，鲁棒性好，性能优越。
English Description：
IDW inverse distance weighted method, based on wavelet transform digital watermarking algorithm matlab code, the use is common plane wave expansion method, the DC-DC part of the constant power single loop control, LDPC code codec implementation, good robustness, superior performance.
