Ask for sobel.png in marble slab

[arumrum]

Hi,

Thank you very much for your software development. I am currently working subtracting background with high noise and interested in your program called marbleslab().
In the program there's sobel.png. Could you please tell me what kind of image that i should attach there.

Thank you

Hi, the codes you study, is not the solution, they are written for experiment purpose only(removed already).

I tried three solutions, all written in

feature_matches();
histogram_backprojection();
threshold_segment();

But none of them work well for the real world project(it may work for yours, not sure). In the end we decided to use depth to segment out the marble, the marble will put onto conveyer belt, and take the photo at certain distance. If your case is much more complicated than this, you may consider semantic segmentation or object detection by deep learning. I could help you build this kind of software if you like, but it wouldn't be free.
