this consist of matlab codes for image compression using 2-d wavelet transform.

实现对图像进行二维小波变换，实现图像压缩，并实现图像的压缩传感-Implementation of 2-D wavelet transform of image, image compression, and image compression

隐马尔科夫树模型，这是一个自包含的程序包，包括2维离散小波变换和逆小波变换 例程。在每个子带中每个刻度的所有小波系数都绑在一起，避免了模型的过度拟合。-This is a self-contained package including the 2-D DWT and inverse DWT routines. All wavelet coefficients at each scale within each subband are tied together to avoid ov
