Here's a production scale apple sorting and packing system. The part of the video for "big plant" shows the most automated version.
Here's a system for sorting peas. Each individual pea is inspected using computer vision. Each individual pea. Anything that doesn't look like a perfect pea is kicked out by an air jet. Take a look at the speed at which the system is running, as a wide conveyor belt feeds hundreds of peas per second through the machine, with the good ones coming out on one conveyor and the rejects on another. That one machine is doing a job a thousand hand sorters could not do.
Automated cherry grading. This video has a good explanation of what's going on, as size, color, stem length, and defects are all checked by a computer vision system. That system can process over 700Kg/hour of cherries. "We're enabling our clients to massively reduce their sorting staff."
Tomato sorting machine. This video has slow-motion sections so you can see the tomatoes being sorted. The machine is far too fast for humans to even see what it's doing.
There are vision-based sorting machines for almost every kind of produce, and they're in wide use all over the world. All this automated sorting means that customers no longer need to examine produce in the supermarket. The rejects were removed at the plant, and turned into animal feed or something. This makes services like Amazon Fresh possible.
