A two-stage algorithm, called switching-based adaptive weighted mean filter, is proposed to
remove salt-and-pepper noise from the corrupted images. First, the directional difference …

A novel way to implement a color image filter is introduced here. The quantum-dot cellular
automata (QCA) framework is adopted due to its adequacy to implement highly parallel …

A new modified 2D (3* 3) multi-shell median filter (MMMF) for restoration of images
corrupted with impulse noise is presented. This filter can not only reduce impulse noise but …

A multichannel filtering approach is introduced. The framework is used to correct impulsive
noise and other image impairments in TV signal transmission. The principles behind the …

Accessing graphical information poses significant challenges for individuals with visual
impairments. In this paper, we propose a novel approach to enrich the accessibility of …

It is shown that for a particular window size, by changing gradually the minimum and
maximum operators to the higher and lower order statistics of the shell, respectively, the …

In this paper, we propose a new method to solve the problem of fixed-valued impulsive
noise reduction in images. Nonlinear filter like the median filter (MF) is useful for reducing …

In this paper, a simple fuzzy-based algorithm to remove the impulse noise from images is
proposed. To achieve real-time applications, the proposed filter architecture, which …

Real-time imaging has application in areas such as multimedia, virtual reality, medical
imaging, and remote sensing and control. Recently, the imaging community has witnessed a …

In this paper, we propose a fast algorithm to realize parallel median filter for processing 1-D
and 2-D signal. In the proposed pipelined architecture, m-passes are employed for filtering …
