Two Dimentional Stationary Wavelet Transform
[A,H,V,D]=swt2(X,N,wname]) [A,H,V,D]=swt2(X,N,Lo_D,Hi_D) SWC=swt2(X,N,wname]) SWC=swt2(X,N,Lo_D,Hi_D)
swt2 is two dimensional discrete stationary wavelet transform utility. Input matrix size must be multiples of power N of 2.
x=rand(512,512); [A,H,V,D]=swt2(x,3,'db2'); | ![]() | ![]() |
