I love this video this time it is again proved fruitful in terms of learning. Best thing about your videos is that you apply simple and conventional methods which are more fast and efficient than modern classifiers. I would love if you make a video on shape context and OCR. It would get alot of hits as these old algorithms are long forgotten but they work best in some applications. With minimal training data and fast execution time.

Hey, can you pls tell me from where can I get the code of this workshop.

Thanks for this workshop. Could you also post a video on how to detect tables in document images or segregate tables, text, charts and figures. Tx.

Your coding style is very unique. 🔥👌

Your tutorial helped me a lot. 😊

Hi, can u explain, why sometimes we need tensorflow and keras for image processing especially object detection,and why somestimes just use opencv, can opencv handle itu without TF and keras?

very cool tutorial. thank you Murtaza.

I keep having the same issue when trying to use the Cascade Trainer, an error message shows up when i begin the training. OpenCV Error: Assertion failed (ssize.width > 0 && ssize.height > 0) in cv::resize, file D:\cv\opencv_3.2.0\sources_withTextModule\modules\imgproc\src\imgwarp.cpp, line 3492 Any ideia of what it could be?

thanks for your video, it's nice ~

good job 👌👌 thank you for vid 😊😊

I find your video very informative, I thank you a lot for that. But can you please tell me wheater cascades can be used for face recognition also ???

You should deserve with 1M subscriber. Amazing

is it possible for me to use the casade trainer in order to detect the printed single rules lines of a CR or excercise book, if so what sort of images should i give the positive and negative folders??? I hope you can help me in this matter.Thank you.

very good channel to follow

i love your content

ver sus tutoriales es como ver a Ronaldiño jugando futbol "Fantastico"

Thank you Very much

Cool tool and thanks for sharing this workflow! The cascade.xml file is not generated with my costume dataset..may you can help?

I read on forums that the negative image size can be larger than positive images but aspect ratio must match. Is that true?

Can I use haar cascade to classify different arduinos like arduino nano, arduino uno, arduino micro etc

Depends on the object. If you are trying to find a simple object based on color or shape it could be done with images processing techniques. But if you have complicated object then you might want to look at AI models such as Yolo
