Impulsive noise in images: a brief review

Alenrex Maity, Rishav Chatterjee
2018 ACCENTS Transactions on Image Processing and Computer Vision  
Impulse noise is one the type of noise which modifies the pixel values randomly. This type of noise can be classified into two categories such as static and dynamic (random).  ...  Some other classifications [1, 2] are available through the image processing filed such as additive, multiplicative and impulse (random) noise.  ...  In 2014 Iterative unsymmetrical trimmed midpoint-median filter was proposed by Kumar and Abhilasha [25] .  ...

A novel adaptive tolerance filter for random valued impulse noise suppression in digital grey and color images

Geeta Hanji, M. V. Latte
2015 Journal of Advanced Computer Science & Technology  
During acquisition, transmission, storage and retrieval, quite often digital images become noised and mask the important details of an image and also present themselves with an ugly look.  ...  Such images if not processed properly, become useless for subsequent image processing operations like segmentation, classification etc.  ...  Acknowledgements Authors express their deep gratitude towards the peer reviewers for providing feedbacks and valuable suggestions to improve the quality of the manuscript.  ...
