We introduce some applications based on MAlib technology. Have Fun !! (Please read some important information described at the last of this document).
Gnodempa is an application to play chroma key composition. Chroma key composition is one of video processing method to compose with object image and CG image or some other image taken somewhere as background.
In general, to make chroma key image, the object is placed in front of blueback screen. Blue pixels in object images are discarded and composition is made by merging object pixels into background image.
But it is not easy to prepare blueback studio in our home. This program enables chroma key composition without blueback screen by extracting the pixels representing human body color.
Download source code and build them with
./configure; make; make install.
To build sucessfully, it needs that GNOME and MAlib (> 0.5.0) are installed into your system.
Get the latest MAlib source codes from here.
At first, type gnodempa from shell.
It may only show the background image, because you did not
complete color configuration.
To configure the recognition color area,
run this program with -c option. All
you have to do is to type 'gnodempa -c.'
When this program start with -c option,
main window shows negative image, and color configure
window (shown below) pops up as sub window.
The scope located on the right side of sub window represents the recognition area. You can configure by dragging that scope and also you can change the size of region by dragging 'mouse picker' on the lower right of this scope.
Pixels recognized as representing human body are shown in main window
normally. This function enables you to confirm the recognition
parameters interactively. The adjusted parameters are
registered by "save" button. These values are saved
into $HOME/.gnome/gnodempa file.
gnodempa can change the background image, using
-b option.
Example screenshot is shown here.
Could anyone challenge making CG like "Dempa Shonen Studio" ? If you can do so, please contact to MAlib development team, thank you.
This program makes "Avatar" controled by estimation of user position with recognizing the video images from many point of cameras. MAlib technology is used in 2D image recognition part.
