How can anyone charge money for this? The videos are only 2-3 minutes long, each featuring just a single slide, and the content is essentially just 'fluff' (empty talk). On top of that, the instructor wastes time explaining very basic concepts that, in my opinion, anyone signing up for this course should already know. It feels like the author doesn't really understand the subject and just threw this course together in one evening. Thankfully, I watched this through a subscription and didn't pay for it separately.

By Vijay on 11/16/2024

This course takes you to an exciting journey in the world of OCR, Computer Vision and Cloud Computing. Every module is well designed and at the end of every module, you feel truly enriched with the learning. A 5 star to the instructor for being so detailed and thorough with each lecture and a special mention to code walkthroughs that truly stands out.

By Rishi Javeri on 3/28/2024

The hands-on guidance on popular tools like OpenCV, Tesseract, and Spacy, coupled with real-world solutions for Invoice Processing, KYC Digitization, and more, truly sets this course apart. I highly recommend this course to anyone looking to delve deep into OCR and become proficient in extracting data from images and PDFs using Python. Kudos to the instructor for delivering such a comprehensive and impactful course!

This course has been exceptional ! The real-world projects, in-depth code explanations, and instructor's prompt in-course support truly set this course apart. The comprehensive content, including deep learning models and practical solutions, has equipped me with invaluable skills. Thank you for a transformative learning experience.

By Violet on 5/2/2023

I was recommended this course by one of my senior colleagues to get a hang of how to develop OCR solutions and this course has some really great stuff. As a Python developer, I found this course very engaging and descriptive. Text Recognition and Text Detection are pretty complex topics but the way the instructor has explained it in the course is amazing. With the help of notebooks in the course and live projects, I have quickly ramped up on OCR and Computer Vision. The best part is the code walkthroughs which are so detailed that it looks like someone sitting with you and explaining the code for each block. Great Job !!

By Max Somer on 4/26/2023

I will rate this course as the best course on Udemy for learning OCR and Computer Vision from scratch. Key highlights in the course would be the instructor providing clear explanations of concepts, source code running smoothly, exciting projects, and quick responses to any queries. Thanks, Vineeta for providing great insights on the advanced OCR project I was designing, your suggestions are very practical.

By Pavankumar Nani on 6/24/2022

Should have explained how each model is working internally and a bit more walk over though each project in the code part. but overall got an idea about how OCR is being done.

By Nicola Sgambaro on 5/31/2022

Il corso è chiaro, semplice ed introduttivo. Manca della parte in cui si vedono nel dettaglio i problemi che si riscontrano nel caso in cui l'OCR non identifica correttamente il testo, quale pre-processing delle immagini va applicato? quali sono le best practices per ovviare alla problematica? E' nel suo insieme un ottimo corso sull'argomento.

By Simon Davis on 4/8/2021

If you're looking to master OCR and stay ahead in AI, this course is a must! It bridges traditional OCR with next-gen AI techniques, offering a perfect mix of theory and hands-on practice. Whether you're an AI professional, a data scientist, or a developer looking to enhance your skill set, this course provides everything you need to build state-of-the-art OCR solutions. What truly sets this course apart is its integration of LLMs, RAG, and Generative AI, making it highly relevant for modern AI applications. Highly recommended!
