Hi , for an internship I need to detect some pigs. I can separate them to the background but not separate one to another when they are too close. I'm starting to learn image processing so maybe I'm doing bad. Do you have any advices for me ?

For segmentation, this will always be an issue. That is why people invented object detection algorithms. Have a look at those.

We've had similar problem with cars detection on my job.

What we came to is neural networks (YOLOv3 to be precise) because only they were able to give quality of detection + separation that is good enough for our needs.

Maybe that's not exactly what you're looking for but that's what solved problem in our case.

Hi! Thank you for your question!

I think BeatColor's article about Clipping Path and Masking is useful for you. It introduces the photoshop techniques used to cut out the subject from the background!

Once you have detected both, check for aspect ratio. If its more then divide the detected image into half.

Thanks for your answer but as you can see here "https://i.stack.imgur.com/npek3.png." they can have différents shapes so i can't use the width to separate them.
