LEARN OPENCV in 3 HOURS with Python | Including 3xProjects | Computer Vision
ฝัง
- เผยแพร่เมื่อ 7 พ.ค. 2024
- In this video, we are going to learn everything required to get started with OpenCV in Python. We will be using Python since it is one of the most popular programming languages. And it has opened numerous job opportunities in various sectors. We will start from the installation process right up to creating exciting projects such as detecting colors, shapes humans, and even vehicle number plates. So If you are a beginner don't worry this course is for you. We will skip all the boring theory stuff and focus on the practical implementation. So you can get the computer vision skill set you have always wanted in your CV. By the end of the course, you will become familiar with the core principle of OpenCV and apply different techniques to solve real-world problems using computer vision.

first . thank you very very much ..this is a great work,...second i wish from you to make a tutorial for self diving car using neural network .finally all the best for everyone
goood video and jobs ;)
Hi, thank you very much for this long but useful tutorial. I must say I'm a newbie with opencv and python. I'd like to know if it would be possible to decode the hour, minutes and seconds of analog watches using opencv. I've this professionnal project. We develop such a program at work but using proprietary library and we have now some limitations with it : it doesn't work with 64bit Windows and due to a bug that we found in the library we can't update Windows and we do need to pay to get the corrected version of the library ! Damned ! So it would great if we could do that with opencv and so use another OS. By the way, we need to decode a datamatrix code to recognize the watch we're processing (just a number). For each watch, we define some templates (ROI) for the watch face, the hour hand, the minute hand and the second hand (the center ans axis of each and the edges) and then the program decodes the hour. Do you think that this possible to do with opencv ? Regards

dude i just discovered your channel and i cant believe that there are so many useful videos about opencv in even all youtube lol. you are a walking treasure please keep up...
Thank you so much for this valuable course. I was new to Open cv and It took me 3 days to go through this video completely. Now I think I will be able to go through your other projects effectively. Thank you so much Murtaza.
just 1 video to clear all the confusion I had in years. you deserve more then 1 like.
thanks so much.

This needs to be on free code camp.
Make your channel more popular by slightly diversifying your content, and video lengths.
couldn't say better!!!!
Alexson Chu, you just articulated what I was feeling. My 1000 likes for the creator of this video!!! Awesome.............
It's nice how he is so friendly when explaining like even intermediate programmers don't have trouble he doesn't use such huge complex words. It's good for that reason as beginners learn easier that way.
You are amazing Martaza. Your teaching skills are probably one of the best on youtube. I hope you're channel grows. Thank you for the free information and tutorials. Wish you the best!

Man thank you so much. I've spent all of my Machine Learning studies working with theory, Random Forests, and Linear + Logistic Regression. Getting to finally break into computer vision thanks to someone who knows what they're doing is huge, I appreciate you. I haven't finished your whole playlist yet so I can't recommend anything sadly, but something I am interested in making is a distance detector. Basically a computer vision application that shoots out one "laser" and detects the distance at that lasers end point.
I am working on something similar. Have you developed something like that?
Thank you for compressing all this useful OpenCV knowledge into such a short tutorial!! Very helpful
Very clear explanations and careful step-by-step instructions! Love your work!
We need more Toturial like this. Thank you.
struggling a few of these topics. thank you so much for the effort to put this together and share the knowledge! appreciated!
Wow, how could I never hear about this channel before?
Amazing content, you got another subscriber.
Thanks a lot for this amazing course. Very effective and helpful to quickly get up to speed on openCV.
This is excellent, you have a new sub. looking forward to going through the rest of your channel!
Welcome aboard!
This level of articulation is a testament to your deep understanding of the subject. One of the best.
I have become a fan ! Definitely recommend to anyone who just came to the course.
Just finished chapter 7 , which was great. Chapter 5 blew my mind , it was very interesting!

Done all in 1 day, but that was hard :) also figured how to do face detection using webcam, just by using your tutorial. Great work ! thanks a lot
Wow!

Just went through it, great tutorial! Very well explained!
So finally i am almost done with my final year project.
It helped a lot !
Thanx for a detailed explanation for free !
Awesome video. I do have 2 projects that required computer vision and being a Mechanical engineer and phyton illiterate did not help the project. This really opened up a massive door that was blocking my way. The words to express my gratitude and thanks are not invented, yet.
I have a question on line detection. I noticed you always use GaussianBlur before using Canny and push the Blur image to the Canny Function. Is there a certain reason why you use Blurred image instead of the standard gray scale. The gray scale produces a sharper image which will result in sharper edges, Right??

Thank you for your tutorial on OpenCV with python. I am usually working in C# VS and I would LOVE to have a tutorial in real time quad (four independent ROI's) for SFR (Spatial Frequency Response). This can be used for an EVK / Dev-Kit image sensor with lens looking at a slanted edge target (B/W) on optical axis. Essentially, it is recognizing the slanted edge gradients and since this is slanted, it reduces pixel (imager side) noise due to the diagonal cross section of how the ROI's read the edges. Mind you that each ROI will have real time MTF readings on all four sides. so 16 total MTF values which can be updated ~ 1.5 seconds. This is well know in online GUI apps and I do not want to utilize their approach. So Something fresh from you would be outstanding to say the least. This should be less in complexity compared to facial recognition but I thought I ask you please.
Simply amazing. Thanks for your hard work putting all this together! I know how hard it is to put 30 minutes videoes together.... great job!!!
Glad you enjoy it!

Thank you a lot. Your video is concise but informative. I actually enjoy your teaching style than most lecturers on Udemy about machine learning.
41:29, There's a shortcut to put cv2.FILLED. Just put '-1' as thickness and it will get filled. Works with all geometric shapes- rect, circle etc
The benefit of cv2.FILLED instead of -1 is that it's more readable and the programmer who will read your code in the future will not have to go check the documentation on what -1 means. It's always a best practice to use human understandable words instead of numbers. The very reason Enums exist.

If you are getting an error at 2:34:45 Make sure your webcam is pointing at the image, mine was on the table and would immediately error out. As soon as I adjusted the page to be in sight, It warped. :)
tried this didnt change anything can you help me out?
@@Bell0 So long as you followed everything up until this point, All I can say is I had to keep trying to run the program and moving my webcam to different positions, the program needs to see and image to warp, if it doesn't, it will crash or not run and throw an error.
