wenergy2

Energy Statistics from two dimension multiple level decompostion

Calling Sequence

[Ea,Ed]=wenergy(c,s)
[Ea,Eh,Ev,Ed]=wenergy(c,s)

Parameters

Ea
: energy percentage of approximation coefficent
Eh
: energy percentage of horizontal detail coefficent
Ec
: energy percentage of vertical detail coefficent
Ed
: energy percentage of diagonal detail coefficent, vector
c
: coefficent array
s
: size array

Description

wenergy2 is to calculate the energy percentage of approximation and detail coefficent for two dimension decompostion.

Examples

x=rand(100,100);
[C,S]=wavedec2(x,3,'db2');
[Ea,Ed]=wenergy2(C,S);
