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!

I am ur big fan sir. Could you please suggest me which method I have to apply for" detection of pinholes(very tiny holes) in aluminum foil" I am absolute beginner please guide me

@ComputerVisionEngineer Жыл бұрын

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! 😃💪

@kamrangul2876 Жыл бұрын

@@ComputerVisionEngineer thanks dear sir . basically I want to do real time(video processing) detection and counting of pinholes in aluminum foil(my semester project).the mechanical structure contains roller that will fold and unfold the foil and between the rollers there be will a dark chamber because the pinholes are very tiny (and some are large too) so I want to make the tiny holes visible by passing light through it in a dark chamber . 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

@ComputerVisionEngineer Жыл бұрын

@@kamrangul2876 passing light through the foil to highlight the pinholes is a very good idea! A threshold may help you to get the pinholes once they are highlighted.
