Raindrops don't just come in any arbitrary shape. They might be pushed into arbitrary shapes momentarily, but surface tension will cause them to adopt a particular kind of shape in general.
In the example photo photons are passing through the droplets as they move towards the sensor. Since the droplets have a continuous convex shape, like a lens, above the surface on which they're photographed this results in gradient effects which would be a detectable feature of raindrops.
Another feature of raindrops would be their blob-like appearance. Detecting blobs alone isn't sufficient for identification specifically as raindrops, but it's a contributing piece of evidence. Many weak classifiers can make a strong one. Similarly cells in microscope images may be detected with blob operators, even though their shapes may be highly variant.
