“…Data hiding based scheme takes the benefits of redundancy and conceals the error quite effectively in burst error condition, even though there is some quality degradation due to data embedding at the transmitter. Since both our method and [30] are developed on the basis of data hiding, the results and the argument are valid for both the cases. But our scheme offers better results for high data loss condition as multicarrier concept in data hiding i.e.…”

“…The performance of the proposed method is compared with both the non-data hiding [29] and data hiding based method [30] intended for the application of error concealment. It is observed from the results of Table 4 method offers better PSNR values when the size of the lost blocks are large or for the lost blocks with small in size but large in numbers.…”

This paper proposes a novel multicarrier spread spectrum (SS) watermarking scheme for the application of image error concealment using multicarrier-code division multiple access (MC-CDMA) with binary phase shift keying (BPSK) transmission in Rayleigh fading channel. The goal is achieved by embedding important information (image digest) which is extracted from the original image itself, and is used to introduce sufficient redundancy in the transmitted image. Half-toning technique is applied to obtain image digest from its low-resolution version. At the decoder side, data demodulation as well as watermark decoding are done using minimum mean square error combining (MM-SEC) strategy. The extracted image digest is used to correct the damaged regions. The integration of SS watermarking with the existing SS modulation not only simplifies the design but also offers significant performance improvement for error concealment in fading channel. Authorized users having the knowledge of code patterns for SS watermarking can only perform the error concealment operation and the method is secured. Experimental results duly support the effectiveness of the proposed scheme.

This paper addresses a loss concealment technique of image transmission in error prone environments. Imperfect transmission of imagery results in the loss of lines or blocks. Previous concealment techniques utilize the spatial, spectral, or temporal redundancy of the imagery. We propose a supplementary loss concealment technique that uses a data-hiding method. We divide an image into 8×8 pixels blocks and generate block description information of each block. The block description information is inserted into other blocks in the same image through LSB-based data hiding. Missing lines or blocks during transmission are restored by extracting this block description information. The technique to resist against lossy compression is also considered. We have performed a simulation to show the outstanding performance of the proposed technique in comparison with other loss concealment methods.
