Separating Y from UV channels (example pic included)

[FLM]

Hello everyone...

I want to take and image from a capture I made and separate the luma channel from the chroma channels like in these pictures:

How can it be achieved? is there a filter for avisynth that can do it or can I do it with any other program?

Thanks in advance for your help.

You can use Tweak (http://avisynth.org/mediawiki/Tweak).

Tweak(sat=0.0) for the luma picture.
Tweak(cont=0.0) for the chroma one.

Or stack them together

StackHorizontal(Subtitle("original"), \
Tweak(sat=0.0).Subtitle("luma channel (Y)"), \
Tweak(cont=0.0).Subtitle("chroma channel (UV)"))
