Block loss recovery using fractal extrapolation for fractal-coded images
A new algorithm is presented for recovering the blocks lost with the cell loss in the ATM transmission of the images coded by Jacquin's fractal coding. The key technique of the proposed BLRA (block loss recovery algorithm) is a fractal extrapolation that estimates the pixels in a lost block by rising the contractive mapping parameters of a range block homogenous to the lost block. The proposed BLRA is applied to the lost blocks in the iteration of decoding.
