Murtaza's Workshop - Robotics and AI

Күн бұрын

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.

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

@PerfectHilton Жыл бұрын

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.

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.

Great Tutorial, im looking forward to learn ESP32. it will be very helpful if you could do a series of lessons on esp32, and how to program using Arduino.

Chapter 9(Face Detection): If anybody's encountering an error like this: (-215) !empty() in function detectMultiScale Try calling the xml file this way: faceCascade= cv2.CascadeClassifier(cv2.data.haarcascades + 'haarcascade_frontalface_default.xml') and then: faces= faces.detectMultiScale(imgGray, 1.3, 5)

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. :)

@@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. I used IVCam and my phone as the webcam, you could try that!

Sidenote: For Chapter 7 and Project 1, ditch conversion to HSV. It's buggy and completely unnecessary. Just do BGR and everything will be much more intuitive. Obviously, for Hue (now Blue), replace min/max from 0/179 to 0/255. Works perfectly.
