TL;DR: The results show that the proposed method outperforms most of the basic algorithms for the reduction of impulsive noise in color images.

TL;DR: In the proposed method the redeye effect is detected using a skin detection module and eye colors are restored using morphological image processing, which is computationally efficient, robust to parameter settings and versatile, as it can work in conjunction with a number of skin detection methods.
Journal ArticleDOI
Random walk approach to image enhancement
TL;DR: The probabilistic algorithms of noise reduction presented in the second part of this paper are able to eliminate strong noise, while preserving edges and image texture.
Journal ArticleDOI
On the reduction of impulsive noise in multichannel image processing
Bogdan Smolka,Andrzej Chydzinski,Konrad Wojciechowski,Konstantinos N. Plataniotis,Anastasios N. Venetsanopoulos +4 more
TL;DR: The proposed method outperforms all standard algorithms for the reduction of impulsive noise in color images because it filters out the noise component while adapting itself to the local image structures.
