Script to detect and select simple shapes? - tomatoSauce23 - 09-22-2024 I'd like a plugin to be able to detect and then select simple shapes in a layer or image. So there is a green square in lots of pictures I'm processing and I have to mark them every time they occur, so I do this manually using the Rectangle tool. The squares are always of a similar size and colour. Is there a plugin that could detect squares within a certain size-range and colour-range and then select them? If not, how difficult would it be to write a script like that, given that I have some programming experience but not in Python?

Hi, this problem is interfering I think... RE: Script to detect and select simple shapes? - Ofnuts - 09-22-2024 Ok, so the question you are asking is a typical one for computer vision, so maybe you should learn Python (which is very easy if you already have programming experience) and check the openCV library. With Gimp, I would try this:

Thank you. So, I hadn't ever heard of computer vision before, and a quick look suggests to me that the openCV library is a library of programmes written in the common programming languages for various tasks that people have use for. So, am I right to think that you are advising that I go there and see if there is already a programme available to do the task that I'm asking about? and if so, then I guess that all would happen outside of Gimp and inside whichever programming language I choose (Java, for example). So I'd find a programme in the openCV library that would find those squares in my images and crop those images to those squares. As for those Gimp instructions, I reckon I could follow them manually... and then are you saying that it would then be possible to write a Python script that does all of those steps as a plugin?

Yes to both. |
