Hi every ones
I have a problem when I code matlab program and really need your help
I have a binary image (only 0 and 1) I use haar wavelet transform by matlab code : [LL,LH,HL,HH] =dwt2( f, 'haar'); I also have four subimage
LL : has maximun is 2 and min is 0 ( in this we have 0 - 0.5 - 1 - 1.5 - 2)
HL and LH and HH: have max is 1 and min is -1 ( in this we have -1 - (-0.5) - 0 - 0.5 - 1)
But now, because this is a binary image so I want our result just belong to 0 and 1. May be we can use low passfilter is OR logical and high passfilter is XOR.
But I don't know how to explain this and code, Please help me.
Thank you so much
