This "convex shape," Bob, sounds v. vague.
You're going to have to explain how that can account for one of those drops
being fairly triangular, another being fairly oval, and another having a
trident formation. To recognize them, you have to be able to recognize the
whole. -Here, you would have to explain how your basic "convex shape" (if
it exists) can be somehow transformed or multiplied to form any of the above
shapes- *and* an endless diversity of new shapes.
I suggest, to repeat an idea expressed before, that - v. v. broadly of
course - the general principle by which the brain understands all these to
be waterdrops is vastly more parsimonious than any geometric approach.
It starts with *any* drop shape - and it theorises about the *principles of
transformation/transfiguration* which underlie changes of drop forms. They
will depend on directly playing with the drops, or having played with
similar bodies.
In the same way, you can look at a piece of plasticine and observe/theorise
about the principles which underlie its transformations/transfigurations, as
you and others play with it. ONce you've played with plasticine you have a
sense of its possibilities.
These will always be fluid (non-geometric) principles [unless the objects
are geometric] - but different for each type of body. Drops of water
transform in different ways to pieces of plasticine to streams of lava to
sreams of waterfalls. ANd the brain is alive to the differences. (Note, I
suggest, that as I itemised those different forms of matter you
automatically had a sense of their different flows).
So to recognize a new waterdrop shape (or not) - the brain asks : " could I
reshape/ play with the existing shape[s] I already know to produce that new
form?"
The basis of this process is robotic/embodied and not the disembodied, blind
manipulation of regular geometric shapes.
The principles I am outlining, I suggest, can account for an endless
diversity of shapes - once you've played with plasticine, it's evident that
you or others can produce an endless range of new kinds of shapes that you
haven't yet thought of. Plasticine shapes radically different from those
you have already seen, are not going to surprise you.

There isn't a formula/algorithm for raindrops, for example
Raindrops do have identifiable features. In the example shown these have
a convex shape which produces a diffraction effect similar to
magnification. Because of the continuity in elevation above the surface
the diffraction effect is also continuous.
The features of a visual object can occur on different scales or
dimensions simultaneously. So "a mess" may have little in common with
other messes in terms of localized descriptors, but have a similar fractal
dimension or algorithmic compressibility.
