hi everyone, im new here.. basic4android is awesome.. anyway i like to ask is there any color detection library? what i really want to do is:

1. user will start the camera and it will be a cursor at the center of the screen.
2. when user point the cursor to object for example white shirt, then a label will display "white".

This would involve taking a frame snap shot,
and then analyzing the center pixel RGB of that snap shot jpg
then displaying the text over the camera frame preview
of the RGB Color name

Interesting.

and it's being done:

Should be possible with the Advanced Camera Library by which you can work with the preview picture. XverhelstX could help you here as he wrote the library.
