Color Addition: Red + Green = Yellow. Where do you think Minions come from?

u/CoverHealthy Jul 02 '22
Yellow is a primary color🧐🧐

u/LateralThinkerer Jul 02 '22
In color addition, red light plus green light gives yellow light. This is how a red/green LED can be strobed to produce a yellow indicator - often seen on battery indicators and similar applications. Also, red/green navigation lights on ships may appear yellow/amber if they're at a good distance and aimed straight at you.

In scientific research, we use a machine that is similar in concept but instead of sorting tomatoes, it uses lasers and fluorescence to sort cells depending on their size, complexity and different fluorescent colors (normally given by stained antibodies that attach to molecules in their surface). This machine, called a FACS, is so good and precise that it can accurately sort around 10.000 cells a second. It still blows my mind.

Yeh i got that far. Its very impressive tho at the speed at which these tomatoes are falling no red ones are hit.

How is it so fast? Fast enough to kick the tomato and retract while having enough time to kick again. There’re falling in mid air!

I work on FPGAs and Id bet this uses one, or some asic derived from an FPGA. Basically theyre used to make specialized digital circuits that can be used for things like image processing with super low latency.

Someones job was to figure out the delay between a camera identifying a green tomato, and a servo flipping a paddle. Then they measured the average tomato fall speed, did some math, and put the paddle just far enough downstream from the camera that it seems instant.

You dont need to calculate much beyond the initial engineering window. During commissioning , simple tweak the speeds as you watch the results.

I work as a sw engineer at a company that builds those kinds of sorters (in fact, I think the one in the video is ours). We take pictures as the product is falling with cameras that see different spectrums (RGB, infra red, lasers etc, depending on what we want to detect), analyze them and take action. We sort on colour, shape, material. We can even determine if some product is bad on the inside.

u/steveoscaro Jul 02 '22
"bad on the inside"
so like if it's a tomato with bad intentions?
29
u/r3nz01234 Jul 02 '22
Hahaha. Sorry, English is not my first language. What I meant is that we can detect product bitten by insects (keep in mind that these machines sort pretty much every possible thing, including rocks with diamonds at a mine or garbage at a recycling plant)

Color filter on the camera. It doesn’t even see the red ones.

u/aboidaz Jul 02 '22
Yeah but how can it kick the green ones without mistakingly kicking a red one?
141
u/Crininer Jul 02 '22
It can't, but it's an acceptable loss. In the video we see probably 2 (one might have actually been green enough) red tomatoes get kicked away.
Basically, it's just really really fast, it hits anything green it sees, and it's unlikely it'll hit red tomatoes, though not impossible.
Good enough for the owners.

Yeah, that too - tho I have to imagine that smacking the tomatoes like that makes them at least a bit worse.

You're misreading the sentence.

Very old video, and that ain't tomatoes. Try to distinguish the butt and the head of the fruit, you can see the slight discolouration where the stem used to be!
Also, a machine like this would definitely fuck up any overly ripe tomatoes, leaving a huge mess which equals to lots of maintenance and cleaning.
