Locally Adaptive Passive Error Concealment
for Wavelet Coded Images

Joost Rombaut, Aleksandra Piˇzurica, Member, IEEE, and Wilfried Philips, Member, IEEE



Abstract—

This letter presents a novel locally adaptive error concealment
method for subband coded images. For each lost low-frequency
coefficient, we estimate the optimal interpolation weights
from its neighborhood. The calculation of the interpolation weights
is optimized in the mean squared error sense, and it takes into account
the errors that would arise by horizontally and vertically
interpolating the available neighbors of the lost coefficient. Compared
to methods of similar complexity, the proposed scheme estimates
the lost coefficients more accurately: on average, the PSNR
is increased by up to 4.5 dB. The reconstructed images also look
better, and our method is fast and of low complexity.
