Diffusion géométrique pour le masquage d'erreurs de quantification et de transmission sur des images JPEG couleur

In this paper, we propose a content-based transmission error concealment method. Unlike classical FEC/ARQ error correction schemes, our method requires no extra control data, and take advantage of spatial redundancies contained in the source image. It consists in interpolating error-free decoded spatial information into corrupted areas, using a coupled multi-resolution/geometry-driven diffusion process. Beside transmission errors, this diffusion model can also be used to conceal quantization errors (compression artifacts).
