Free visual difference software for linux

Visual difference metrics can predict whether differences between two images are visible to the human observer or not. Such metrics are used for testing either visibility of information (whether we can see important visual information) or visibility of noise (to make sure we do not see any distortions in images, e.g. due to lossy compression).

The image below shows how two input images, a reference image (upper left) and a distorted image (lower left), are processed with the VDP to produce a probability of detection map (right). Such probability of detection map tells how likely we will notice a difference between two images for each part of an image.

Red color denotes high probability, green - low probability. Red color is mostly present in the areas where there is a snow covered path. Because of smooth texture of the snow, there is not much visual masking and distortions are easily visible.

Although there are dozens of visible difference metrics that serve a similar purpose, our Visual Difference Predictor for HDR images (HDR-VDP) has two unique advantages: firstly, our metric works with a full range of luminance values that can be meet in a real word (HDR images), and secondly, we offer a complete source code for free.

High Dynamic Range Visible Difference Predictor (HDR-VDP) can work within the complete range of luminance the human eye can see. An input to our metric is a high dynamic range (HDR) image, or an ordinary 8-bits-per-color image, converted to the actual luminance values. The proposed metric takes into account the aspects of high contrast vision, like scattering of the light in the optics (OTF), nonlinear response to light for the full range of luminance, and local adaptation.

Test::Differences Perl module contains test strings and data structures and show differences if not ok.

SYNOPSIS

use Test; ## Or use Test::More
use Test::Differences;

eq_or_diff $got, "anbncn", "testing strings";
eq_or_diff @got, [qw( a b c )], "testing arrays";

## Passing options:
eq_or_diff $got, $expected, $name, { context => 300 }; ## options

## Using with DBI-like data structures

use DBI;

... open connection & prepare statement and @expected_... here...

eq_or_diff $sth->fetchall_arrayref, @expected_arrays "testing DBI arrays";
eq_or_diff $sth->fetchall_hashref, @expected_hashes, "testing DBI hashes";

## To force textual or data line numbering (text lines are numbered 1..):
eq_or_diff_text ...;
eq_or_diff_data ...;

Visual F-Prot is an F-Prot Antivirus for Linux Workstations graphical interface.

Visual F-Prot is graphical interface for F-Prot Antivirus(TM) for Linux Workstations for home use (available for free download) copyrighted by Frisk Software International (www.firsk.is). Before you install this program, you must install F-Prot Antivirus, because it wont work without it.

It works with F-Prot antivirus version 4.5.3 and above - its not tested with earlier versions,but it should also work with them.

Also, youll need "xterm" terminal emulator, provided by most, if not all linux distributions.

This program is built with GTKMM 2.4 C++ libraries, so youll also need those for it to work.
