[Mr. Spiegs]

After some strenuous testing, we were able to effectively get grip to find the bolder. My advice to you:

- Using the image processing given, work on try to detect blobs or contours (whichever is more beneficial in the long run) to create an outline of the bolder

- Mess around with color saturation (we used black and white) in addition to some sort of blur as a way to make a more structured object that looks more whole than the simple contours or blobs pictured in basic

- There is a custom color script that works like a color drop that's available somewhere online (I'd look for it but am kind of tied up for a while). We had some success with it, but we found a slightly more effective way following our usage.

I wish you luck with whatever trials in the future!
