upcoef2 - Two Dimension Direct Restruction

Calling Sequence

Y=upcoef2(type,x,wname,[N],[S])
Y=upcoef2(type,x,Lo_R,Hi_R,[N],[S])

Parameters

Description

upcoef2 is for upward two dimension reconstruction from any desired input matrix.

Examples

  x=rand(100,100);
  [cA,cH,cV,cD]=dwt2(x2,'db2');
  Y=upcoef2('a',cA,'db2',1);
