Irish travelers will be deeply hurt that OCR and even you don't accept that dag is a word.
Has no one ever tried to sell you a dag?
Or admired your dag?
Ya like dags?
Knackers do not even speak english ;)
hey kid, you wanna buy some dags?
Oh, dogs. Sure, I like dags. I like caravans more.
This is the post I was waiting for.
FILE FORMATS AS FAST AS POSSIBLE!
png vs jpg
mp4 vs mkv
mp3 vs ...?
James Klein MP3 vs WAV
mp3 vs flac
James Klein png keep the quility
MP4 and .mkv Is not a file format, IT is a container. And ITS not many difference between mkv and MP4 the only difference is that mkv can hold some more codecs.
SmartFyrHD Also Matroska can also embed multiple subtitle formats (SRT, SSA/Advanced SSA)
OCR was one of the first practical uses of neural networks back in the 70s or 80s. Maybe even earlier? When I took an AI class in college, we wrote a simple OCR neural net and it was pretty easy.
the OCR can use different techniques to recognize character, one is creating a model based on data of different characters and training the sofware to recognize them( Artificial neural networks is an example of this)
That was the smoothest transition to a sponsor spot I've ever seen.
I didnt even realize it was happening
Will it also recognize language?
because "dag" translates to "day" in Danish
Is there anything on this world that recognizes danish?
Nope, as a Dutch guy i can read it just fine, but when it is spoken.................I quit.
Same result when translated to Swedish xD
I would assume it sticks to one language, but some can probably change their language. Also perhaps some could be able to determine the language based on what it has already recognized.
It's from the movie Snatch
When Luke said it wouldn't look as crisp and the video resolution went down I instantly checked if I was at 1080p
Yeah me too
Highly recommend PaddleOCR! 80 languages supported! Good performance! Easy to use! It would be great if bloggers could do a comparative evaluation of the popular OCR tools.
I gotta say, I really liked this one! Very informative but what really made it for me was the seamless sponsor spot. I'd love to see more in such a way!
that's good and all but I would have thought you'd give us and idea of what kind of devices use OCR for consumer/business.
I love how Luke explains stuff :D
I was going to ask "How about Voice Recognition next?" but searched your channel, and I'll be damned, 1 year ago, you guys work fast! (Not sure how I've been missing it though, alot of content much?).
It's a shame neither is "How to create your own Voice Recognition and Optical Character Recognition as fast as possible"
Well, with OCR, there is an exception for the lack of accuracy. When basic modern OCR was being developed, they made a series of fonts deigned to be as accurate as possible. These fonts were OCR-A and OCR-B. These fonts are super accurate with OCR, and there is usually never any error with them.
There are also programs for character recognition on your screen.
Project Naptha is a Chrome extension that can let you copy and paste words in an image.
And ShareX has OCR that you can use for any program.
well google releases a OCRT (optical character recognition translator). which translate even other character aside from ASCII (chinese, japanese, thai and other non alpha character)... it become useful for those who travel and find themselves trap into a place where no one can speak or understand english.
In my industry, which is electronics. We use OCR in our automated optical machine to detect component marking on components as small as micro BGA's that are like 400microns wide. It's amazing to see how you can push it's limits. Just, sometimes like when there's a sufficient amount of flux on the components it makes it impossible to read.
What is the best scanner that does the same job as your devices
My ScanSnap IX500 usese software to make scans readable. It works pretty well and the IX500 is blisteringly fast.
Haven't read a single comment regarding the video's topic.... only "First", "Notification Squad where you at" and comments trying to be witty.....
Great video by the way, i love getting general introductory information on the subject of my studies (computer engineer). Keep at it TechQuickie :D
Google translate app with OCR is pretty nifty when you can translate foreign signs etc.
I did some OCR recently. Tesseract on Linux was the best at recognising the text accurately, but it outputs plain text only. There are 3rd party GUIs, but still none really preserve formatting.
ABBYY FineReader on Windows (the gold standard for home use) was quite good at preserving formatting but worse at recognising text accurately. My scan was 200 pages of black 12pt Times New Roman on white paper scanned at 300dpi which should be one of the easiest things to process, and it regularly made mistakes on 1 vs l vs I , y vs v, H vs II etc. And these were often in places the dictionary should have easily known what it should have been. How often do you get a lower case L in the middle of a long number or a double upper case I at the start of a word or a v at the end of a word. It took 3 hours to go through the document correcting the mistakes it highlighted. Don't know how many mistakes are in there that it didn't highlight.
Is that an 8k green-screen video? Looks super clean
Hi! Could you do a FPS 1%low explaination? I have seen so many tech reviewers use this term but i have no idea what it means.
Long Nguyen Games tend to have "stutters" (i.e. briefly running out of VRAM on say, a 1060 3gb) which can temporarily bring the minimum fps incredibly low. So 1% lows are used. All they mean is the minimum fps that doesn't factor in the bottom 1% of frames, to give a more realistic minimum
Could also be called the 99th percentile.
Thank so much for you explaining Sir.
Linus ad (pulseway) on linus video. I love this ahahaha
same gahahahahah
But can OCR ever distinguich hand written numbers and letters from eachother? Such as 0's & o's, G's & 6's, 1's & i's ,H's & 4's , j's & i's, 7's & 1's ,0's & 8's etc,,,, because numbers and letters looks similar to eachother.
I've tried Tesseract. Its free and pretty accurate.
You should do an as fast as possible on assistive technologies such as screen readers
This is the first time i've watched a tech video and actually not had a headache after. Waiting for the interpretive google dance hehe
Saw OCR and immediately thought it had something to do with the Exam Board.
bradad111 Lool same
So did youtube, i was watching a revision playlist and here i am??
Which OCR recognizes Handwritten text that you have shown at the end? I couldn't find anything which actually does that within a permissible error rate :/
luke are you finally using linux? i saw that little ubuntu font box :D good job mate!
we need a firefox plugin that will log what youtube upload has paid promotions, skip past it and end the video when teh promotion happens.
this video is an example of native advertisting
Just what I was looking for. Good Job!
convolutional and LSTM neural networks are the cutting edge for these applications
OCRs font work ive tried them but they dont properly. They dont read encrypted documents they spit out random incorrect letters.
Sir can you tell me how can i find duplicate numbers with any OCR app or how should i pursue to make an app for that ?
Thumbs up if anyone else checked the videoquality at 0:36 xD
I downloaded but , I thought that it will recognize the different fonts that are someonetimes in just ONE page. Does anyone know an APP/Program that can recognize the font on a scanned document?
I couldn't help but to think of the line from the movie Snatch when Brad Pitt said "ya like dags?" lol
I mean tbh ... when I write in OneNote some text and microsoft can figure out what I just wrote and convert it into real characters I'm always astonished since my handwriting is horrible.
Micky: Ya like dags?
Tommy: Dags?
Micky: Yea, dags
Tommy: OH, dogs, sure I like dags
So I guess the real question here is why is Luke only wearing socks while recording this? Doesn't Linus give sandals to all the employees?
Dennis: "You are dancing?"
OneNote has a pretty good built in OCR for small text articles - and it's free !! ABBYY FineReader does an excellent job converting image PDFs into searchable text based PDFs !!
Can you do video on Virtualization such as hardware, network and storage Virtualization.
What if it's supposed to say dag, that's also a completely legitimate word used in Australian English, plus it could also be used to describe a Directed Acyclic Graph, also known as a tree.
could you do videos explaining how mastering audio and video works? (if it doesnt already exist)
I've got a Chrome extension that does OCR within images. Sometimes comes in really handy.
Dag is in swedish day
TPS reports!!!!!! What a perfect example. Almost an easter egg.
Make an episode on network topologies
Linus tech tips as fast as possible
Speaking of machine learning..... that would make a good techquickie :D
Dag is a word OCR software would not pick this up spellcheck does not pickup this also
Very useful knowledge and easy to understand provided to the new faces of this technology.
Techquickie you do know most scanning software do this as part of their operation. If your's doesn't perhaps you should get a new one.
If the software were dutch, the word would be "dag" (which means day in english), and not "dog".
Do speech recognition as fast as possible please.
What about if you're trying to copy the line "D'ya like dags?" from Snatch?
Can you please tell me about any OCR software for devanagari language .
Which can cost me less
Images in video editing?
Dag actually means Hey or day in Dutch!
Bas Roelofs dag means bye too
I love u guys man
You should explain core parking in the near future.
Tesseract is the best OCR program out there. It is Open Source and runs on all major OS
How can I run it on Windows
why isn't there an OCR software to scan videos?
I mean, there are literally one or two, and they can't do much.
It should be relatively simple since a video is composed by images.
But I can't find ONE program that does that.
And why doesn't Google release a standalone app/software to OCR things since it's OCR is the best? I'd pay for that.
I don't think OCR on video is all that practical. Plus you'd have to do things like work out if it's the same text but scrolling between frames, recognise transitions and animations, and also deal with the processor time that analysing at least 24 frames for every second would take.
barnstormer322 Well, yes but it's not mandatory to analyze every frame in real time, even if i think Google could do it if you have a good upload speed to upload frames to them in real time.
also I think It would be VERY useful for the anime community, and not only for that.
to distinguish text from animations should not be that difficult since there are freeware that already do that ,it just need to be improved a bit.
do you like dags?
I really like Tesseract withHomebrew on Mac for OCR.
I liked your dancing, ignore dennis. great video.
YEES More history please. love knowledge.
So use a normal "photographic" scanner , then use OCR services such as google drive .
Man, the ACR was great. Hardly any recoil
Wow, I saw this video right near before my National exam days.
Luke - I actually watched the ad because of your fresh moves!
what about Fourier transform?
Not one mention of neural networks?
Printing costs like 150 dollars for new ink if you go to retail, if you manage to go online it costs like 10-20 bucks. What the actual fuck?!!?
4:11 That's not actually writing, is it? Because if it is, it beats _my_ character recognition.
Cool! Thx a lot.
What did Dennis say?
great video!
I used to use an augmented translator app for my French tests. Shit just about worked half the time
Nice dancing, Luke
Who else had nostalgia @ 0:36?
Is there any awesome free software that do this? Linux or PC. Besides Google drive that is
I WANT INTERPRETIVE DANCE TRANSLATOR NOW!!!
This isn't in 4k! :(
I liked this "don't worry, be happy" in your video. Are you a Meher Baba lover too!!!!
Oxford Cambridge RSA
Anyone else thing the green screen looks a little wonky? (I feel like I shouldn't be noticing that it was green screened)
Luke, you have to tell me when you go on tour -- I need to leave the country at that point....
OCR is not for "pikies" apparently...
Brad Pitt will be furious
Arizona's audit brought me here 🇺🇸
Funny used OCR last night. What a coincidence
3:33 dag is actualy morning in dutch
Soon, we will have OCR AI to eliminate all those errors. Now, we have to worry about putting the data onto the correct column in Excel because OCR thinks the second column belongs on the bottom and the third column is broken up into two column... *sigh*
dag is a word in Norwegian :)
Ha en fin dag
Vel, ha en fin dag i morgen :)
it's a word in English too. poo hanging from a sheeps bum
Vilken trevlig dag vi har, eller hur?
Its an English word too, but I think it must mostly be used in Australia/NZ
I want to see the Google interpretive dance translater
When did Dan Reynolds start doing tech stuff?
Thanks
