The output of waverec2 is not always consistent with the input of wavedec2. For example, the following
import numpy as np import pywt nx = 129 ny = 255 data = np.random.randn(nx, ny) alpha = pywt.wavedec2(data, 'db1', mode='zero', level=1) xrec = pywt.waverec2(alpha, 'db1', mode='zero') print(data.shape, xrec.shape) print(np.abs(data - xrec[0:data.shape[0],0:data.shape[1]]).max())
produces
(129, 255) (130, 256) 1.7763568394002505e-15
They do at least seem to be consistent within the overlap region. Is this the expected behaviour?
