this code for watermarking image using wfilters db2, if this code using wfilters db1 or haar its ok no problem

error message is : _Array dimensions must match for binary array op.

Error in idwt2 (line 90) x = upsconv2(a,{Lo_R,Lo_R},sx,dwtEXTM,shift)+ ... % Approximation.

Error in testtanpadouble (line 35) Watermarkedimage_final=idwt2(Watermarkedimage_level2,LH,HL,HH,'db2');_

please help me for my final project
