Many physical phenomena are described by first-order differential equations whose solution
is an exponential decay. Determining the time constants and amplitudes of exponential …

A family of nonlinear filters based on order statistics is presented. A mathematical tool
derived through robust estimation theory, order statistics has allowed engineers to develop …

The median filter is one of the basic building blocks in many image processing situations.
However, its use has long been hampered by its algorithmic complexity O (tau) of in the …

Paintings, frescoes, antique photographic prints, incunabula, old books, handwritten
documents, sculptures, ceramic fragments, and other ancient manufacts constitute the …

In this paper, a thorough review is presented of noise reduction filters for digital image
sequences. Detailed descriptions of several spatiotemporal and temporal noise reduction …

The manipulation of pictures and video in digital form has been an established research
activity for more than twenty years. It is only recently, however, that digital image and video …

This paper presents a number of model based interpolation schemes tailored to the problem
of interpolating missing regions in image sequences. These missing regions may be of …

The authors propose a novel adaptive spatiotemporal filter, called the adaptive weighted
averaging (AWA) filter, for effective noise suppression in image sequences without …

Bright and dark flashes are typical artifacts in degraded motion picture material. The
distortion is referred to as" dirt and sparkle" in the motion picture industry. This is caused …

State of the art movie restoration methods either estimate motion and filter out the
trajectories, or compensate the motion by an optical flow estimate and then filter out the …
