Re: 3D medical images

Dear Axel,

to my best knowledge 3D dense graphical models were not implemented so far based on DGM library. Building a pairwise 3D graphical model is straightforward with DGM, but a dense 3D model may require a modification of the inference algorithm.

Best regards,

Re: Installation / Demo file error

The member optional came to C++ starting from the version C++17, and was not present in the C++14 or C++11 or even classical C++98. It looks like your compiler does not support C++17. From other hand the Visual Studio 2019 compiler must support optional. Thus my current guess would be that there is ...

Re: Installation / Demo file error

Hi! the presence of the opencv_world440.dll file in your OpenCV folder indicates that you installed OpenCV with the pre-built binaries. That means that the file opencv_world440.dll was compiled for a specific Windows and Visual Studio versions, which might be different from yours. That's why I would...

Re: Assertion fail in MessagePassing.cpp

Dear Victor-Robles, yes, a very probable scenario for this mistake is that Gaussian Mixture Model as a generative model tries to reconstruct your distribution from the training samples. In the test samples perhaps you have a sample, which lies very far from the training samples (very low potentials)...

Re: DGM Support for more than UINT8 Feature Images

Hi yes, currently the DGM library supports only 8-bit input images and only 8-bit features. This is due to the fact that some note potential models ( e.g. Bayes) can work only with the 8-bit features. However, some of the other models ( e.g. Gaussian Mixture Model) can naturally work with 16-bit int...

Re: Training

Hi Tejan, you might want to build your fully connected CRF upon the Demo Dense tutorial. In order to train the model not on one image but on the set of images, you need to modify the == STAGE 2: Training == section of the Demo Dense.cpp file. Please use the following idea: Timer::start("Trainin...

Re: Mixed Graphical Models with DGM

Hello, It's been a very long time since our last contact. I'm the guy reaching you by email. I see you've put my article's link in homepage. Thank you very much, not just for the link, but DGM, the foundation of my work/research. Thank you for your kind words. I am really happy that DGM library was ...

Re: EmptyMat()

I have some ideas, that I can offer to try. Sorry, I can't try it myself because I can't reproduce the problem. ⋅  Try to add const before Mat & in the corresponding functions' declaration (and subsequently implementation if needed) for one function and check whether the error for this...

Re: EmptyMat()

This is very strange.
Does the problem still appears here?

Code: Select all

e:\dgm-master\modules\dgm\kdnode.h   38

Or at another place with EmptyMat?
Did you run CMake as described in the installation guide? If EmptyMat is replaced with the Mat()?
