In this paper, we present an innovative interpolator that performs high quality 2/spl times/interpolation
on both synthetic and real world images. Its structure, which is based on a rational …

We propose a new algorithm to digitally restore vintage photographic prints affected by foxing
and water blotches. It semiautomatically recovers the defects utilizing the features of the …

We apply the new GenomeBits method to uncover underlying genomic features of omicron
and delta coronavirus variants. This is a statistical algorithm whose salient feature is to map …

The compression of still images by means of the discrete wavelet transform (DWT), adopted
in the JPEG-2000 and MPEG-4 standards, is becoming more and more widespread …

Abstract—A main step for world’s progress is to keep sharing ever-present Ideals for science
and education within today’s Virtual Realities. On-line education is transforming human …

A complete system for old picture restoration is described: in particular, a frame alignment
method, a simple deblotching algorithm and a nonlinear approach for contrast enhancement …

A man-machine interaction project is described which aims to establish an automated voice
to sign language translator for communication with the deaf using integrated open …

A novel noise reduction system for video sequences is presented. It is based on a simple
and accurate estimation algorithm, which is used to enable a filter in a suitable set of rational …

The Lucy-Richardson algorithm is a very well-known method for non-blind image
deconvolution. It can also deal with space-variant problems, but it is seldom used in these cases …

In this paper we present a digital image enhancement technique which relies on the application
of a nonlinear operator within the Retinex approach. The basic idea of this approach is …
