Wavelet & Multiwavelet Lost Block Reconstruction in Noisey Environment
Engineering and Technology Journal,
2009, Volume 27, Issue 4, Pages 717-726
AbstractIn this paper, an algorithm for reconstruction of a completely lost blocks
using the discrete wavelet and multiwavelet transforms are tested under noisey
The algorithms examined in this paper do not require a DC estimation method.
While most of the previuosly reconstruction methods assume that the DC value is
available or a DC estimation is required.
The reconstruction is achieved using the Boundary Interpolation (BI) which is
based on wavelet transform. The algorithm’s performance is further improved
through the modification of the Boundary Interpolation algorithm.
Another algorithm is studied in this paper which is based on the multiwavelet
The effect of adding a Gaussian noise to the image on the performance of
reconstruction of the algorithms mentioned in this paper is studied.
