I have a basic question about cvBlob: Can cvBlob extract blobs without
requiring the user to identify the color of the blob? The examples I
have seen are all based on identifying a color. I'm looking for a more
general foreground/background discrimination algorithm. Thanks! --Osman

Blobbing is generally done after foreground/background segmentation
has been done.  If you want some other options that are more dynamic
than picking a single color, I'd google around for "Color Model
Segmentation" "Codebook Segmentation", etc.  These types of algorithms
are generally trained with a background image, and then can map
background/foreground to black/white.
