A Comprehensive List of OCR Datasets for Machine Learning
Introduction:
Optical Character Recognition (OCR) is a game-changing technology that allows computers to interpret and convert various types of documents, images, and handwritten text into editable and machine-readable formats. OCR has revolutionised data extraction, document digitization, and information retrieval processes across industries. To build accurate and robust OCR models, access to high-quality training data is crucial. In this blog, we present a comprehensive list of OCR datasets that are invaluable resources for training OCR machine learning models.
MNIST (Modified National Institute of Standards and Technology):
The MNIST dataset is one of the most widely used benchmarks in OCR research. It consists of 28x28 grayscale images of handwritten digits (0 to 9) and their corresponding labels. While primarily used for digit recognition, MNIST serves as an excellent starting point for OCR beginners due to its simplicity and accessibility.
IAM Handwriting Database:
This dataset focuses on handwritten English text recognition. It contains more complex and varied text samples compared to MNIST. The IAM Handwriting Database includes text lines written by different individuals, allowing OCR models to learn diverse handwriting styles and variations.
Street View Text (SVT) Dataset:
The SVT dataset is designed for scene text recognition, simulating real-world scenarios where text is captured in natural environments like street signs or storefronts. The dataset contains images of scene text along with corresponding annotations, providing a challenging and practical OCR training resource.
IIIT 5K-Words Dataset:
Similar to SVT, the IIIT 5K-Words Dataset focuses on scene text recognition. It consists of images collected from the web, capturing text in various languages and fonts. This dataset offers a broader scope for OCR models to handle multilingual and diverse textual content.
CORD Dataset:
The CORD dataset caters to OCR needs in the medical domain. It comprises a collection of scientific papers related to COVID-19, enabling the training of OCR models to extract valuable information from research documents.
CAPTCHA Images:
CAPTCHA images, designed to prevent automated bots from accessing websites, can serve as interesting OCR training data. Though challenging due to image distortions and obfuscations, using CAPTCHA images can help OCR models improve their robustness and accuracy.
Tobacco3482:
The Tobacco3482 dataset is specifically tailored for OCR in historical documents. It contains images of tobacco advertisements from the early 20th century, offering unique challenges in recognising older fonts and styles.
UNLV-ISRI-ALPR Dataset:
This dataset focuses on Automatic License Plate Recognition (ALPR). It includes images of licence plates with annotations, enabling OCR models to recognise alphanumeric characters present on licence plates accurately.

So, last week I fell two workouts short of my plan, and got ZERO writing done. So, this week I've made modifications. Removed my evening casual mileage two nights a week so i can use those days to focus on book 2. My Monday-Friday lunch gym time is still in effect.Exercise 1 of 8 for the week complete. Leg day! Today's exercises were the same as last Monday, except 40sec sets instead of 16 reps per set. I used 8# weights for all...which is up from last week's 0-5#. My knees are still not happy, so I didnt squat/lunge very deep at all. And overall, the workout was quick. Bonus! I also ended up doing the workout in my home gym, because I forgot my gym clothes. 🤦♀️

Now The Best Rock Climbing Tips For Beginners & Experts
Finger-grip techniques are most essential while free climbing. Mastering those techniques along with synchronizing your body will make your climb faster and efficient. Your body weight should always be centered over your feet to maintain proper balance. Proper balancing techniques are the key to smart-climbs. 👉 Read more about Now The Best Rock Climbing Tips For Beginners & Experts
Optical character recognition (OCR) lets you turn scanned images into text so you can turn paper-based documents into editable, searchable, digital documents. This can help reduce the amount of physical space required to store documents and can dramatically improve workflows involving those documents
bakit sa tuwing workout lang may abs? ~normal times wala bundat...🫧😮💨 train na with us para may abs ka din. 👋 #Spartan #SpartanPH #SpartanRacePH #BeSpartanReady #OCR #OCRTraining #CoachCarloFitness @spartanraceph @fitcampperformance (at FitCamp Cebu) https://www.instagram.com/p/CfT0cbgpy_x/?igshid=NGJjMDIxMWI=
My morning was spent hiking up Koko Head with a friend. I felt 10 times better than the first time I climbed it. Training is working and confidence is growing!
After, we got coffee at this quaint little place on the water and shared our breakfast with the birds ☺️
Later in the evening and after a nap, I did today’s workout.
5 rounds Grind: 10 lunges, 4 pull-ups, 8 burpees
Then a 20 minute AMRAP: 5 sandbag tosses, 10 sandbag drags, 100m run with sandbag. Then I worked on a few rope climbs- want to be used to climbing in a tired state. I think the rope climb in the race is near the end.
Enjoying that sunshine ☀️ & gettin in that training any chance I get! 🤙 Next event is the @deka.fit Mile #relentless #pushharder #ocrtraining #ocr #spartanrace #spartanathlete #tireflip #HIIT #fitnessmotivation (at Ithaca, New York) https://www.instagram.com/p/CSHEf_ZAa67/?utm_medium=tumblr
Perfection is a goal that will forever remain impossible for any human being to achieve 🤍 "Toss your hair in a bun, drink some coffee, put on your shoes ~ and handle it 🤍
I stepped away from posting on social media this weekend to enjoy the finer things in life and now my soul is rejuvenated 🤩🤩 This weekend was the first full weekend of the #stayinside orders and it was nothing short of perfection. Friday night we ordered takeout from a local sushi burrito joint, @pokeburriraleigh, and I'm pretty sure it was the best "fast food" sushi I've EVER had! Saturday we made a quick run in an open top jeep to get me a bike and then we went on a 2 hour long bike ride down the Greenway (I'm still feeling the effects of this 😂😂) followed by celebratory mimosas! Sunday was a day of yard work. We transplanted a hydrangea which was struggling big time (here's hoping it survives 🤞🏻🤞🏻) and transplanted a cedar tree which was beginning to take over our driveway! What most people don't know about us is we're introverts. We prefer camping and hiking over social hangouts but we also know friends are EXTREMELY important for our happiness and we are counting down till when we can be social again. Until then, we will continue to enjoy the social distancing in our usual ways ❤️❤️ #ocrtraining #ocr #savagerace #bonefrog #ruggedmaniac #spartan #ocr #socialdistancing #stayhealthy #staysafe #yardwork #friendships #rejuvenation #sushi #pokeburri https://www.instagram.com/p/B-WkWYphjrW/?igshid=1xkkt35tkslnh
