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

[@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.

[@jeff3257]

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

[@murtazasworkshop]

I am glad you found them helpful.

[@ilthizamimtiyas3482]

This is gonna be my favorite channel

[@bemresolvido8856]

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

[@rafaelneri5701]

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

[@murtazasworkshop]

Glad you like them!

[@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.

[@quahntasy]

*Absolutely marvelous.Loved it thanks.*

[@murtazasworkshop]

Glad you enjoyed it

[@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

[@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.

[@the4hunters]

You my friend, are a legend

[@user-lk5lj6vm7o]

Thank you so much! It was a great help. You explained them easy!🖐🖐

[@anmolpunetha3994]

It's gonna be a great tutorial again. Great

[@nejatkaraca]

Thanks alot Murtaza. Good video.

[@hiraokii]

Amazing bro, I am using all knowledge that u have been sharing. Thanks so much

[@murtazasworkshop]

Glad to hear that

[@KChen-ks4le]

very well explained tutorial, thanks for sharing!

[@omkarpatil8720]

can this be used for measuring 2metes x 3meters rectangle dimensions if we change reference polygon to 4 x 4 meters instead of A4 paper dimensions. Also what is the accuracy of measurement for this application?

[@robertobaldizon8206]

Amazing videos. Thank you very much.

[@harishsivasubramanian161]

Great tutorial! Where can I find the image which you are using?

[@shreyankkamalapur6201]

Thank you sir. Great tutorial

[@idriss1717]

Good job! Can you show me how to measure the distance between two things in an image, please?

[@shoter3967]

Thanks alot broo u are perfect ☠️

[@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.

[@chockalingamathilingam4396]

wonderful video story and easy to understand without code

[@edSabio572]

Great tutorial!

[@luqmanharits1456]

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

[@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

[@user-tn8qp7ys5m]

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

[@tanakronplatinums]

Thank you so much Teacher

[@averno6174]

As allways, amazing, clear, thanks again for your work

[@murtazasworkshop]

Thank you! Cheers!

[@mariorodrigues1888]

i'm a rookie on pytho but my thesis is arond this kind of application, do you know if it precise on circles, or do u think it can be applied for precision ?

[@siddharthrana512]

Hi sir , i am intrested in your mobile app course , but i have a small question that in scanner , can we learn to scan the items and pay and go like system??

[@nuramirabintiabubakar824]

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

[@ayyappahemanth7134]

I love your videos and able to write opencv on my resume because of your videos(main contribution).please video on text recognition from scratch sir

Mind blown!

[@thaniaansaliputriprasetio4421]

hi, I have a question. your program, is soooooo good, but on my computer, they don't give an accurate size, what do I have to do to fix that problem, sir? thank you

[@jayanthr248]

You're awesome!

[@Liebendan]

Would this be usable on farm to measure animal height via cam would it need a set white background and static distance from item and could it knownofnits same cow fir example and add on of it has grown?

[@science4allworld587]

Excellent..

[@amoghmilindpatwardhan175]

Should the refenrence object and other objects should be in same plane?

[@kacpermalczewski6186]

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

[@geraldmusandirire5446]

Can this be used to measure the distance of an object from the camera?

[@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?

[@mikilmku1554]

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?

[@nataliameira2283]

Excelente! Adorei!

[@claudiomiranda2]

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

[@Skilled7105]

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

[@glazeinfotech1555]

i am great full to you sir

[@abhimanyukspillai6572]

Kindly help. My final output is scaling down (even without dividing by scale variable). Why does that happen?

[@cuonggenie]

awesome job. Thanks so much

[@murtazasworkshop]

You're welcome!

[@ajoras9197]

Can it calculate dimension of the object if it is placed in different backgrounds

[@vishaljakkulwar1918]

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

[@shauncs]

wonder what your dev machine configurations are. Mine it's a core i5/16GB ram and it takes more than 3-4 mins to run the program where as yours runs instantly :D

[@jothegamechanger]

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

[@PabloLucio]

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

[@rowanmeaney9028]

I am following this tutorial but when I try to run it I get the error of "append() takes exactly one argument (5 given)" (this line was written right around the 20 minute mark) - can anyone help?

[@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

[@FahadKhan1]

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

[@arielrahmansyaharifin6187]

I have a question, how if I only want to measure a single line?

[@omkarpatil8720]

Murtaza what if i want to measure big objects lets say 750 mm square object....what limitations are there for big objects can we measure flawlessly

[@jokosusilo303]

Hi, amazing tutorial as always. I have a question, does it only work with the image taken from above the object (or 90 degree angle)? Thanks for this lesson..

[@ashutoshfulzele2442]

ya if we use top view image then it works fine..else for some angular view, we use 'warpPerspective'

[@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

[@nadiatisalsabilla8898]

you have a great tutorial but when can i get the tutorial if i want make distance detection between camera and object?

[@circuitdesigner7489]

please tell the points in which you have put text 'cm', it is not visible in the video

[@Syed-kr6hd]

Bro please help me i am getting error at the last part the you've pasted it's not visible clearly please give us full screen view and thank you for this

[@shroukkamel1526]

What is the way to add the image path to the pycharm file, such as Image 1.jpg, to video

[@errakkaskhalid2562]

please i want to calculate the diameter of an orange or an apple in a picture, how i will do it

[@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.

[@ahmedemam5276]

Hi i want to know convert pixel distance to cm distance like i use human pose estimation and get distance between right and left shoulder in pixels how to convert that to cm thanks in advance

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

Great work bro, Can you tell me about the camera....is it fixed while capturing real time image or I can move the camera too? And Without providing height between the camera and your card, how can you find the exact length and breadth. I mean, it may vary as per the distance between the camera and card.
