here data is given and estimate using ML estimation in pattern recognition

清华大学信号课程第二次实验，内容是基于傅立叶级数的信号分解以及双音频按键音合成(Tsinghua signal course the second experiment, the content is based on the Fourier series of two-tone signal decomposition and synthesis of key tone)

this code first reads an image and decomposed it in discrete wavelet transformation.hl1 and hl2 are extracted to embed watermark. watermark is added to hl1 and lh1 and inverse dwt is applied.
