I think there's an Ae plugin called AE pixel sorter. Be great to hear if anyone knows how to go about doing something like this in VUO.

You could use Feedback Image.

You could use Feedback Image. The thing is on your image it only selects some pixels so you would have to determine which those would be, the brightest pixels, specific colored pixels etc.

Or mask images.

Here is a test composition and I've added some nodes that could help finding the effect you want, just play with those.
