This review article provides a comprehensive survey on state-of-the-art impulse and
Gaussian denoising filters applied to images and summarizes the progress that has been …

This study presents a comprehensive survey on mixed impulse and Gaussian denoising
filters which are applied to an image in order to gauge the effects of this type of noise …

Removal of random valued noisy pixel is extremely challenging when the noise density is
above 50%. The existing filters are generally not capable of eliminating such noise when …

In this paper, we present a patch based weighted means filter for removing an impulse noise
by adapting the fundamental idea of the non-local means filter to the random-valued impulse …

In this paper a Threshold based Directional Weighted Median (TDWM) Filter for Removal of
Random valued Impulse Noises (RVIN) from digital and Infrared Images, has been …

In this paper a two phase scheme has been proposed for removal of random valued impulse
noise from digital gray scale images. First phase detects the noisy pixels and second phase …

An offline signature verification system (OSVS) is an industry-driven technology with the
ability to verify and recognize a signer's signature, as required for different situations such as …
