Close, but let me restate it a little bit. The key operations are the threshold (color or brightness), the convex hull, and the particle analysis. The example does not do edge detection, though localized edge detection of the particle on the original monochrome image may improve depth information slightly and may provide more info about the location on the field.

These key operations also tend to be the expensive operation, along with the image decoding from jpeg. I believe that convex hull tends to be the most expensive operation, with threshold next, and decoding next, but the cost of each is somewhat dependent on the data in the image and the parameters on the calls.
