In this 1-hour long project-based course, you will learn how to collect and label images and use them to train a Tensorflow CNN (convolutional neural network) model to recognize relevant areas of (typeface) text in any image, video frame or frame from webcam video. You will learn how to extract image segments that your detector has identified as containing text and enhance them using various image filters from the OpenCV module. Then you will learn how to pass the result image to Google's open-source OCR (Optical Character Recognition) software using the pytesseract python library and read the text to whatever form of output you like. All of this will be done on Windows, but can be accomplished with very little alteration on Linux as well. We will be using the IDLE development environment to write a single script to scan our video, webcam input, or array of images for text and read that text into our output. Tensorflow, the Tensorflow Object Detection API, Tesseract, the pytesseract library, labelImg for image annotation, OpenCV, and all other required software has already been installed for you in your Rhyme desktop. Note: This course works best for learners who are based in the North America region. We’re currently working on providing the same experience in other regions....

The course videos are not sufficiently concept clearing. A few lecture videos alongside the hands on project would have been really helpful.

There are few interresting ideas here, but the most off-putting thing is that the creators didn't really put an effor in creating good quality product. 1 hour of videos consist mainly of a guy typing the code into the notepad. He explains it verry briefly and gives no guaidance about how to configure the whole environment on your own.

It includes a lot of pre-coded modules and it is not possible to run them on our own PC. not very useful and it is not very helpful to have them in this way.

The course is very poorly organised. The instructor is ambiguous, just starts the course with typing off a script without bothering to state why he as doing so and forr which part of the Project the starting script is important or relevant.

He talks about a image_samples folder in my "virtual desktop" but there is no such folder to be found at all! I have attached a screenshot of what is visible in the discussion forum. This has been a wastage of time and money for me! I do not expect such standards from Coursera. This is verging on fraud. Please verify the QUALITY of your products before you start charging money to people!

Even though the topic of this course is very interesting and the tools employed in it are frequently used to solve some Text Recognition and Computer Vision problems, I could not recommend this course since, in my opinion, the Rhyme platform disappointed me in a way that makes it impossible to go together with the course for the second time.

The platform is not helpful to practice and there is no support from RHYME. They don't give us the train material to practice on our on PC if their platform is such a congested. I had very bad experience, I wasted my time and money for nothing.

I did not like the approach of typing all the code, instead I propose having those files in the virtual desktop and fill out important parts of them; just like a puzzle with missing pieces.

Low quality

No explanation indetails, can't run in local environment, only suitable in the online sandbox. Don't but it! The most disappointing course I meet in coursera.

Total garbage. tons of code but no explanation. does not cover required packages.modules nor how to set things up and there is consistent errors in code that is used. Do NOT WASTE YOUR MONEY!
