But | using a pic of the whole plant got an accurate ID. | [deleted] | AnonC wrote: | I've tried Seek by iNaturalist [1] to identify some plants in | real time (the app can also identify fungi and wildlife).

Will have to try on mushrooms etc! | | Sometimes when it didn't seem to give a high accurate match it | says 'dicots' for the family. | | It said hemp family for my hops, I guess it's hard to get an | exact match of hops, unless they're flowering I guess. But | impressed it got that, it seems a hard problem! | | Edit: it did get hops eventually after trying a different angle | :) | jccalhoun wrote: | I heard about this app on the radio yesterday and I literally | just got back inside from using it to identify a plant outside | my house. It worked ok. when I went to install it, there were a | number of other apps that came up in the app store and I | downloaded picturethis which identified the plant instantly | whereas inaturalist gave me a list of possible plants to pick | from. picturethis has some in subscription stuff going on that | I didn't look into tough. | faitswulff wrote: | I haven't tried Seek, but I've had better luck with animals | than with plants on iNaturalist, personally. It's useful to | algorithmically ID the plant family. | wiremaus wrote: | Myco-nerd here: absolutely never rely on the image recognition | apps for fungi ID. | | There are fungi in entire different genera that are VERY | morphologically similar, and the apps are just not there yet -- | likely won't be for a few dozen years. | | An app can make a lethal mistake much easier than a human. | boulos wrote: | I've used Google Lens as "if it says unsafe, definitely | unsafe". I would not rely on it for "oh yeah, I can eat this" | :). | | I doubt your "few dozen years" though. Humans are only so | good at it themselves. Computing has improved a lot since | 1984 (3 dozen years ago), and so I'd wager that by 2050 we | can be better than human at "Eat or not?" for fungi. Up for a | longbets.org wager? :) | thatcat wrote: | Other sensors combined with photo would likely be the | solution and the results might not be instant for some | samples. | TaylorAlexander wrote: | I mean the thing about fungi is that the tops can look the | same and you just need to do a spore print to positivity | distinguish one from another. There may be some mushrooms | which are simply impossible to tell apart by outward | appearance. In one of the fast.ai lectures Jeremy shows how | to distinguish different breeds of cats. Then he shows how | to look at the confusion matrix, and he found one pair of | breeds the network really struggled with. It turns out they | look really similar to him too, and when he researched | further he found they're simply hard to tell apart. Perhaps | with an enormous data set there might be small differences | a network could detect, but the confidence might still be | low. | | And given that mushrooms can kill you, it may simply never | be advisable to rely on any photo based identification. | boulos wrote: | I don't consider it against the rules of the bet to allow | multiple pictures, including the underside and perhaps | even "here, smush the mushroom on a piece of paper and | take a picture of that". My question is can a vision- | based AI thing outperform humans within another thirty | years, not if it can do it via a mechanism that isn't | discriminating. | | For all the myco folks here: Do you have a sense of | whether or not the multiple hours mentioned is "required" | or "just" makes it easier to get a strong signal? (That | is, how much is the signal boost due to our inability to | see well as humans) | | [1] https://en.m.wikipedia.org/wiki/Spore_print | homerowilson wrote: | We foragers and amateur mycologists use smell, touch | (slimy, dry, etc,) sometimes taste (bitter, acrid,...), | habitat (on wood, ground, type of wood, is there a bulb | below ground or a root-like structure, time of year, | spore prints, sometimes color change due to drops of | chemicals (especially on boletes), sometimes even | microscopes to view spores, and more. | | all of these variables could of course be coded for a | good classification algorithm. | | just saying, it's often more than simply visual. | growt wrote: | I tried something similar with Google auto ml a while back. | Although I'm no ml expert, I think it's quite difficult to | identify plants. There are many different parameters like | distance, flowering or not or even time of the year. In some | cases it can also be quite dangerous to mix up plants, like wild | garlic and lilly of the valley ( I hope I translated those right) | 101008 wrote: | I misread it as "identify planets from your pictures" :) | Fiahil wrote: | For french speakers, you can follow the Tela Botanica Mooc on | botanic here : https://mooc.tela- | botanica.org/course/view.php?id=12 | clemParis wrote: | Thanks! | underyx wrote: | I've been using https://plant.id/ for this.

After quite a few attempts with | PlantSnap, it came up with Chinese Hounds Tongue Forget-me- | not[0], which sounded plausible. However, after a much smaller | number of attempts with PlantNet, it suggested Green | Alkanet[1], which I'm starting to think is more likely, e.g. | due it flowering earlier and being more weed like. Not an | expert, and I know this is only one test case, but based on | this I'm favouring PlantNet.
