You are the Real Hero of OpenCV, well done!!!

[@jeff3257]

You have the absolutely most professionally looking tutorials on KZbin. Super helpful!

[@murtazasworkshop]

I am glad you found them helpful.

[@rafaelneri5701]

I´m a fan of yours video tutorial. I learned python and OpenCv with this amazing videos.

[@murtazasworkshop]

Glad you like them!

[@eij1704]

I've reached the last part of the video but I'm left with some sort of a cliffhanger because it's incomplete and since you've shifter to a different website now, I can't access to the original code. I hope you can put the code back :) much appreciated :D

[@ArunMPEdison]

Great beginner friendly video, Thank you for patiently walking through. Gives a useful insights into how to tap into navigating through the image pixels and coordinates with contours.

[@ilthizamimtiyas3482]

This is gonna be my favorite channel

[@swatiahuja9720]

Amazing! I have been following your tutorials and I got to learn a lot from them. There's a thing I want to implement, Realtime dynamic hand gesture recognition. I couldn't find a suitable source for that one over the internet. Although I could train your traffic signal model for getting a static solution for the same. If You could consider a dynamic project for one of your videos that'd be very helpful.

[@murtazasworkshop]

Thank you . I will look into it.

[@bemresolvido8856]

congratulations for this amazing tutorial. It answered most of the questions that I had. Thank you.

[@HoaNguyen-dr8zk]

Thanks alot! I really enjoy learning this new hard topic! Hope that you are going to make more tutorial instructing us some functions similar to Cognex, Mitsubishi, Keyence industrial vision application.

[@siddharth_bhawsar]

Great Tutorial man, learned a great deal of stuff in one single video. Keep Going! I'm going to check out the deepfake tutorial! Thanks A lot

makes complete sense. Only a couple other tNice tutorialngs I need to find out before I can actually make it work, but you’ve got more in depth

[@jothegamechanger]

Can we make how to calculate how long based on bounding box? (Just bounding box not object like this? How?

[@MiguelRodriguez-wn8mc]

Hello, it's very nice. Your development seems to work very well with square and rectangular objects. Now, what happens if the object doesn't have that shape? For example, a wood shaving, a small piece of paper cut by hand, some shapeless pieces of plastic.

[@luqmanharits1456]

Hello sir, Can the camera measure circles and triangles and other objects? Thankyou

Very good video my friend, but I try it myself and doesn't work well when two objects are touching each other... Do you know how to solve this problem?

[@rengoku2508]

Hi its a good tutorial!! Your explanation is so detail. Can you make a tutorial for object detection and measure distance from camera? It such a helpful for me. Thank you in advance!!!!

[@murtazasworkshop]

Noted

[@rengoku2508]

@@murtazasworkshop thank you for notice me!!!! Its a good help if u can do the tutorial for video not for image 😊

Thanks for nice video, what if i have an object rectangle in shape but round corners. i want to measure the length of the straight portion and length of round corner. Finally, I want to have 4 straight edge length + 4 round corner lengths

[@Skilled7105]

can you make a opencv tutorial on imagegrab and detecing objects on your computer screen?

Can we measure dimensions of a complicated object..like a rectangle and many small circles inside that rectangle?

[@martynaslaucka8147]

I have the same question

[@chockalingamathilingam4396]

wonderful video story and easy to understand without code

[@amaanshaikh6868]

What are system requirement for this project.

[@tanakronplatinums]

Thank you so much Teacher

[@YazeedAlkosai]

Amazing....and very helpful to me...also I have a question on how to measure the 3D model as (heights, width, depth)...if there is a possible way could you tell me how could follow your answers to my question. thanks in advance

[@murtazasworkshop]

Hi. the 3d object measurement would require depth information which could be achieved with a 3d camera

[@nuramirabintiabubakar824]

hi,nice explanation. may i know.. about 1.png it is live captured or difference image from webcam?

[@KChen-ks4le]

very well explained tutorial, thanks for sharing!

Thank you sir. Great tutorial

[@aritahalder9397]

Hi.. your videos r very helpful… can you please let me know if we can read 16 bit images in openCV? If so then how?

[@PabloLucio]

Could this be used for measuring people, like arms length, legs length, etc in real time?

[@vishaljakkulwar1918]

Nice work! Could you add the arrowed line code aswell?

[@kacpermalczewski6186]

How about irregular shapes for example rectangle with a peak from 1 side?

[@QuarktaschemitSenf]

Hey Murtaza, first of all thank you for all your effort and for making the world a bit of a better place, by providing free education. I would like to ask , if there is the possibility to rent you for a teams-call, regarding in depth-questions on yolov7. Greetings :-)

[@edSabio572]

Great tutorial!

[@shantanuroy9408]

Where is the image file?

[@nataliameira2283]

Excelente! Adorei!

[@claudiomiranda2]

esse cara é top d+, ainda bem que conheci o canal dele kk

[@saadwaqar7003]

Great tutorial, thanks!! But how did you convert the values from pixels to mm??

[@QuarktaschemitSenf]

you know how many pixels the 291 * 210 mm of the A4 sheet take --> so you have pixels / mm or vice versa

[@jonilsarmiento3320]

Can i use this for measuring size of fruits?

[@Itsnotmondayyet]

As shown in the starting of the video, how to do it in real time? Like you showed us how to do it with images. How to do it in a real time video?

[@matiastello2330]

Excellent video! I followed your code step by step and I had no problem, I just have a question. How can I make it work with my computer's webcam? Should I replace everything that has the variable "imgContours2" with the variable "cap"? or simply changing the "webcam" flag from False to True?

[@hafizmuhammadabdullahbhatt9047]

Just change the webcam flag

[@science4allworld587]

Excellent..

[@FahadKhan1]

Very nice, how about programming same using C++?

[@adriansuarezdelvillarpomar840]

I love this program, could you please tell me if it will work with clear pieces of glass and how high I can go on the picture. I would like to measure 4 or 5 pieces of clear glass between 12''-35'' x 50''-90'' from 10' of high, do you believe it will work on it?

[@murtazasworkshop]

If you can find the edges of the glass using contours then it can work.

Ur videos r really really aswome sir in ur previous video attendance system u showed that details will be recoreded in an excel sheet sir...so along with that i just want to capture the recognized faces also please tell me how to modify ur code sir this is really really needed to me pls help me

[@averno6174]

Hi, I'm new to Python but according to code in video attendance system you have encoded images in encodeListKnown, a list_variable containing a list of arrays (the encoded values) for each image. If you want to have a pre-trained file with trained images you only have to save that list after training and load it wherever you need. If you want to have a pre-trained file with trained images and corresponding labels, you can create a dictionary from encodeListKnown and classNames (merge both lists; value-index) If you want to add from code new trained images you have to: -get new image of detected face -save it to repo directory (remember the name will be the label) -convert into RGB -encode that new image -append that encoded to encodeListKnown and save it to file And there you are, you have an updated file with new recognized image if I am not wrong. Then append this encoded to dicionary getting updated classNames value if you need second approximation. I invite you to test coding and share your results, I am sure everybody will help you if you try and post code with your doubts Maybe I am making mistakes, I am new to Python you know, but I think this could be a Good solution.

After calling the markAttendance function you can crop the main image and save the image using imwrite. Your croped image would be imgCropped = img[y1:y2,x1:x2] then u can save this with imwrite funciton.

[@averno6174]

​@@murtazasworkshop I wonder if this could work. I don't know if my code is correct and/or I am using properly tkinter. the idea is to label unknown face with user entry, save tha image to images folder and re-encode (retrain) system for the next loop to match. Is code correct?
