How do I split up an image into 40+ polygons?

Hey guys :)

I'm looking to turn 1 image into a lot of smaller pieces, based on color.

Example:

Here's what should happen to this image:

- Split up tiny polygon based on color.

- Paste the original image onto each polygon, so that the image is whole, but made up of 40 separate sprites (or drawing surfaces)

Most of the blueberries should be their own little sprite, and the little black spots as well.

Any help would be greatly appreciated!
