Reviews summary

Real-time ocr with tensorflow, opencv and tesseract

This 1-hour long course focuses on using Tensorflow, OpenCV, and Tesseract for real-time OCR and text detection. As it is project-based, learners will work on a single script to scan video, webcam input, or an array of images for text. Students should ideally have some familiarity with Python and a basic knowledge of Tensorflow. The course works best for learners in the North America region.

The emphasis is on coding.

"Just comment a few lines of code."

"It includes a lot of pre-coded modules and it is not possible to run them on our own PC."

"I did not like the approach of typing all the code"

Access to the platform may be limited.

"The platform is not helpful to practice and there is no support from RHYME."

"The cloud environment has a problem."

The course lacks detailed explanations.

"Almost no intuitive explanations "

"It keeps changing automatically, you have to stop coding, pause the video and click on the button next to the Fit one."

"No explanation indetails"

Expect a challenging course.

"The course is very poorly organised."

"NEED TO HAVE A DEEP PREVIOUS KNOWLEDGE ON PYTHON AND SOME OTHER STUFF TO UNDERSTAND THE CORE OF THIS."

"Too fast, explanation is too vague and the guy seems to assume that we are already too well versed with this subject."
