I am unable to read img in OpenCV
Posted: Wed May 29, 2024 4:02 am
I'm stuck with OpenCV image read function because somehow he can't read an image. Yes the path is correct and the image exist. I watched some tutorial on Youtube to display an image to find the problem without success. I also try to debug to check if my path was wrong but it seem to work perfectly fine so i'm kinda lost. enter image description here
