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);
