I confess that I'm a beginner and I've never programmed in my life, I'm suffering a lot, but I see that with each step I learn a little, I still have a lot of doubts, but that's ok, I'm absorbing the knowledge and who knows, I'll improve, but I'm extremely grateful, very thank you great master.

  • Hello, Felipe. I noticed that when you hover over the images, with the mouse pointer, used in your examples, you get the screen the X,Y coordinates and RGB values at the bottom of the image window for the pixel depending on where the cursor is placed on the image. How is this achieved? Excellent tutorial by the way, thanks!

    • Hey Kamran, thank you for your support! 🙂 It all depends on your data and the requirements of your project, but from the top of my mind I can think in two different approaches: if pinholes are from a different color than the aluminium around them you could try with color detection; if pinholes are 'big enough' and 'distinct enough' from everything around them and everything else in the frames, you could try with an object detector based on something like yolov8. But again, it all depends on the data and your specific requirements. Let me know how it goes! 😃💪

When the holes spots became visible in the dark chamber camera will take an image. I think I should process only black and white images not colourful. Should I also apply some filter or only yolo V8 is sufficient . Thanks again
