OpenCV Python Tutorial #4 - Drawing (Lines, Images, Circles & Text)

[@CubixCreations]

Absolutely wonderful series, definitely can't wait for the next tutorial! Keep on educating us Tim!

[@TIMJR625]

Working on an image/motion detection project right now, these videos came at the perfect time! Good stuff!

[@TechWithTim]

Thanks! Best of luck on your project :)

[@VinodKRamachandra]

I liked the animation used for explaining the arguments. Nice improvement. Thanks, Tim

[@davideddington5432]

Tim, your videos are great and I always learn something new from you. Your style keeps me on track with just the right amount of information to keep me focused and not all over the place like I usually am. Im a big fan of all your videos but I very much look forward to the next video in this series!

[@MrHellmeowmix]

This tutorials been so easy for me to follow, and I quickly feel like I am learning. Thanks!

[@ntechplayz6155]

Great videos, the perfect length to stay interested

[@bradb2012]

[@devhere2457]

Good job, understanding is very esay when learning from tim

[@Littlepunk8964]

2 years later, Tim is still great

[@furina_]

At the age of 5 : Using paper and pen to draw 😭 At the age of 10 : Using MsPaint to draw 😂 At the age of 15 : Using OpenCV to draw 😎 Tim works so hard 😘 so it's the duty of his every viewer to subscribe. Right Tim?

[@copdatchoppa]

Tim is in fact great!

[@AbdolazimHasseli]

You are really great Tim!

[@alialavizadeh2775]

I was looking for this series Tim tnx👍

[@doublej3462]

Hi, I am your new subscriber who from South Korea. I am studying degree Computing Science in Singapore. I watched your video. Your coding skill looks very awesome. I really want to have good coding skills. I am feel very respectful to you

[@manonthedollar]

cv2.LINE_AA enables Anti Aliasing (AA). You can add those to most of the draw functions (including cv2.line, .circle, .rectangle from this video)

[@noertri618]

Nice video, this gives me inspirations

[@Wolf-if1bt]

Where are you from ? I'm french and I can understand 100% of what you're saying. Perfect accent for me. And obviously, your tutorial is also perfect : opencv appears to be easy. Great!

[@VictorPerez-od7zh]

Amazing tutorial Tim!!!

[@parthkabra4968]

I am working on the HTML code generator with element structure. Thanks bro, love u a lot

[@pencilcase8068]

Ima download this vid. Currently doing a maths course but I'll be back for some relaxing programming

[@984jimbo]

Great Videos Tim! A question I have is at 3:52, you changed frame to img so the next line will be drawn on top of img. However, it seems to work for me by just writing cv2.rectange(...)? (So we remove img keep the first argument as frame) I played around with drawing 5 rectangles on top of each other, and defining each cv2.rectangle(...) as img1, img 2 etc. It would always draw 5 rectangles on top of each other, no matter what i put into the first argument of cv2.rectangle(), and no matter which I showed for cv2.imshow('frame', img...) I was wondering if this is the same for you? i.e. does defining img and writing cv2.rectange(img,...) actually do anything unique, since it doesn't seem to for me

[@sanduchicu7545]

12:55 tim: and after that thats baisicly all fo rthis tutorials series... me: WHAT!?! he's already done?!

[@ananthramvijayaraj4554]

HaHa, I got scared and then realised that it was just a mistake by Tim

[@sunwukong6268]

Nice video, again. Great to code along and play around. I am currently taking an online course and it´s rather boring, compared to this. So thanks and I am really looking forward to the next parts.

[@TopMusic-rw3yz]

Thanks Tim!!!!!!!!!

[@LeviWaters-v6d]

quick question! in your video at around 3:23 changed cv2.imshow('frame', frame) to cv2.imshow('frame', img) is there an important difference? I ran it both ways and they both worked. Great video BTW!

[@paulsherlock4348]

I believe that is just the name of the window it’s displaying in.

[@cx3268]

Will you have a video combining OpenCV & TKinter?

[@heliotenm6532]

here beside using cap.get(3) and cap.get(4) for width and height, we can also use frame.shape[0] and frame.shape[1] for height and width, so is there any reason for using the .get() method? He also then convert the value of cap.get() in int, while we get value from frame.shape already in integer.

[@sachinrawat9109]

Using cap.get(3) and cap.get(4) ensures consistency across different video files, not all videos may have frames of the same size, and using the get() method guarantees that you are getting the width and height information directly from the video file

[@electrikvocal9590]

Will you do Hands-tracking tutorials with Opencv?

[@tanphuc4589]

Hey Tim could you make videos about Tkinter module?

[@aariskazi9002]

Hey Tim I want to make curved lines in Opencv can you help me out🙏🙏

[@parthsinghrajput1062]

waiting for this thanks heart

[@sarveshp6584]

which package you are using in sublime ?

[@youssefelamrani7905]

how can we show 4 different video cameras in a single window like the one you did in the video with your camera

[@reold]

Good speed

[@Bridos]

I mean, is it possible to add a simple circle without volume unlike the example?

[@Bridos]

Is it possible to add a donnut instead of a circle with volume??

[@i-MAsif]

Hi , i am using ubuntu but unable to install opencv with python 3.7.3 version there is an error stoping me to go ahead. Would you help me out plz .(using jupyter notebook) 🙂

[@serhii710]

img and frame are the same thing, you can verify it yourself by doing assert id(img) == id(frame)

[@simplelife1643]

hi, can you please help me with my script. i am trying to save the image detected by opencv and yolov5 custom model. and i need to save the whole image when the object detected.thanks in advance

[@syedufaqhaider2796]

I completed your 1000th View at least gimme a Hii in reply ❤

[@JoshelinRico]

The delay when you're drawing on the video stream is very noticeable

[@michaelvogt7787]

Tim. I liked... but 'axis' is spelled like this (not axsis). I chuckled. DrV

[@knbabu5473]

Please make a video regarding django using automated tests

[@popodip3471]

Hello, I just saw you have a video titled 'Why You Should STOP Using an IDE (Integrated Development Environment)', yet you're still using an IDE. Does that mean the video was complete clickbait to waste your viewers time for money, or was there some other reason? Thank you in advance for the answer.

[@TechWithTim]

Hi. Did you watch the video? I don’t feel it was a waste of time otherwise I would not have created or posted it. Funny thing is in this series I’m actually not using an IDE. This is a text editor not a full pledged ide... Before you make such assumptions I’d encourage to watch the video in question, hopefully I can articulate in that video why i titled the video as such.

[@moneyman2087]

Tim

[@macieksikora5043]

I think u make mistake 6:15

[@MahirAshabAhmed]

Please create an api using flask and use docker, want to see end to end project.

[@rudro314]
