The command line VisualBoyAdvance program can be found at: http://vboy.gnemu.com
and not supplied with KVBA, but KVBA tested with VisualBoyAdvance version 1.7 only
Do not forget that for VisualBoyAdvance to run you need the libSDL1.2 package
KVisualBoyAdvance is distributed under the GPL.
Enhancements:

GnomeBoyAdvance is a GNOME frontend for the Visual Boy Advance emulator.

All the options of VisualBoyAdvance are graphically configurable and stored using Gconf.

The controls are configurable with a pressing on the wished key or joystick button.

You can easily manage your roms collection and associate a screenshot to each game.

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.

Visual Oberon is a GUI library written in Oberon2.
VisualOberon (or short VO) is a collection of classes written in the programming language Oberon-2. The classes are designed to let application developer easyliy build graphical user interfaces for rograms written in Oberon-2. _VO_ is distributed nder the GNU library icense.
VisualOberon is _not_ a programming language. While it sounds like he Oberon version of VisualBasic, it is not an integrated developement nvirinment with build in text editor, builder and that stuff. It is urrently just a library. Nevertheless it can be the basis for such integrated environment.
Enhancements:
- Some prototype of a controller class for mapping input to object functionality.
- Improved Edit control.
- Improved file open dialog.
- Menu navigation via keyboard.
- More usage of STRING.
- Improved drawing including support for offscreen drawing.
- Improved Curses version, now works also on black white terminals - but still not perfect.
- Improved image loading.
- Bugfixes, bugfixes, bugfixes.
- Improvement of VGD. Added more VGD handler.
- Support for Xft version 2 as found in newer distributions.
- Packages for Windows and Carbon modules, needed for developing applications for Window sand Mac OS X, used by the coresponding driver module sin VisualOberon.

Visual REGEXP project can easily design and debug regular expressions by providing a graphical visualization of the expression and its matches on a sample of your choice.
Version restrictions:
- some regexp can consume a lot of CPU time. This seems to be caused by the use of -all, -inline and -indices flags together.
- when a subexpression is not matched (empty match), the last character of the previous match are coloured. This is due to a problem in Tcl (bug submitted to Scriptics).
Enhancements:
- new version done by Martin Lemburg. Many thanks, Martin.
- it is now a tcl 8.5a4 starpack
- GUI layout changed to be based on a paned window
- GUI code looks different, to be more ergonomic
- the informational labels (replacements & matches) are now sunken
- there are now additional the "first" and "last" navigation buttons
- there is a new option to navigate through matches or matches and submatches
- the displayed count of matches is changed to display the current and the count of matches used for navigation (probably changes, if the new navigation option is changed)
- the replace widget is disabled on startup
- the tcl console is added to the help menu
- the key bindings inside the regexp text widget changed a bit to allow for expanded regexp (-expanded or (?x)) to contain tabs and newlines. Tabs are created with Control-Tab and newlines with Control-Return. Additional with Control-C|V|X (not c|v|x) it is possible to use the clipboard like with Control|Shift-Insert, Shift-Delete.

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.

Visual Automata Simulator is a tool for simulating, visualizing and transforming finite state automata and Turing Machines.
Visual Automata Simulator is a DFA, NFA and TM simulator.
Main features:
- Creates, simulates and transforms DFA and NFA machines
- Creates and simulates TM
- Batch tests for TM: useful features to test a bunch of files quickly!
- Easy-to-use GUI interface (multi-documents)
- Smart links between objects
- Machines can be drawn using the mouse - and resized at any time
- Multiple machines can be created in a single document
- Multiple documents can be opened at the same time
- Documents can be saved and reloaded from disk
- Debug mode to see exactly how the machine is working (each step has a different color)
- MacOS X GUI compliant.
Enhancements:
- FA and TM machine can be exported to EPS file
- integrated update manager
- preferences: can specify the character used to define an epsilon transition
- fixed a bug where epsilon transition were not considered when starting directly from a state instead of following a non-epsilon transition.
