I believe the last version was 0.11
USE-
A simple plug-in to convert RGB images to YUV in GIMP. This means that after having applied the filter, you will get luminance (Y) in the red channel (R), and chrominances in green and blue channel. By using the decompose plugin, or the channel dialog, you will be able to work in YUV space, and be back in RGB space by the reverse plugin. In fact, combined to the fourier plugin, you should be able to demonstrate a simple JPEG compression on the whole image.

Zip attached includes binary and source files.


INSTALL-
Place the yuv.exe in the plugins folder, and you will find it under - Image>Mode
You will find two more items in the menu :

Image / Mode / RGB -> YUV
Image / Mode / YUV -> RGB

An example
Here i ran Image>Mode>RGB -> YUV
Then decomposed with Colors>Components>Decompose
Then i sharpened the Luminance layer (L Layer).
Then i recomposed the image and ran Image>Mode>YUV -> RGB
Just for an example
