Chaining of different filters (image processing functions)

valera-rozuvan commented 8 years ago

We should think about how to implement chaining of different filters.

A GUI to drag and drop onto a canvas different filters. Connect them, by dragging lines from one filter to another. Something similar to UML diagram editor.
Scripting support. Include a scripting engine (JavaScript, Python, or other), and allow a user to import a script which describes a custom filter as a chain of available filters.
?

@juliena82 What do you think?

Writing a GUI to build a filter chain : good Idea. With the following suggestions:

it should be a different .exe as the ocvdemo (but in the same repo and if needed sharing the same sources), as I think we should beware of "One application, one use case".
This would generate a XML file describing the chaining. And this would remove the need to do special Scripting (unless you call Scripting writing XML files) for point 2)
for the MMI part, we should re-use at maximum existing Library for drawing graphs
This program would have as input XML files (the current database of availble filters), and as output an XML file, so there is no need of OpenCV Library, and there is no interaction with the rest of software and so it could even be build it in a completely different language (why not python or javascript, provided we find a good graph editor in this language)
We would write another program, this time in C++ and reusing the current source code to proceed to the simulation of a previously XML defined filter chain.

What is your opinion ? (these are just my first ideas)

One possibility of Gtk+ library for this job is GooCanvas.

Since you guys are talking about a separate EXE for this, perhaps it is worth considering integrating opencv-demonstrator with BlendOCV. I know the guy who made BlendOCV, so if you are interested in collaborating with him, I can introduce you all. I think he would be interested. One easy solution would be to import/export files between BlendOCV and opencv-demonstrator. So then the projects can stay as separate projects but users can share some work between opencv-demonstrator and BlendOCV.

@valera-rozuvan @shervinemami GooCanvas seems cool. Besides it seems that there is also a C++ version (GooCanvasmm). I had a look at a BlendOCV video, and it looks quite great! And it seems to do already all what is required for the need of chaining different filters. Shervin, do you know if there is an installer available? I would be glad to try it for real.

Closing this issue due to lack of activity.
