In 2D the discrete wavelet transform (DWT) of an image using lifting based 5/3 filter, if I perform a row-wise operation first then perform column-wise operation then I will get 4 sub-band LL, LH and HL and HH.
- During reconstruction, that is IDWT, should I maintain the order in reverse direction that is column first and then row?
- Or any order I can maintain?
- In JPEG 2000 there is no order information found in the header. Then how I can main the order during reconstruction?
