Re: DGM for Ubuntu

Currently we port DGM library to MacOS. In particular the latest version from GitHub (MacOS) may be already compiled and used in MacOS. It is sad, but at the moment we do not concentrate on supporting Linux operating systems. However, since MacOS is based on Linux, I hope it would be not so difficul...

Re: How to improve classification results with DGM

As far as I remember, I recommended to increase the number of training images, but not the number of classes. Usually having more classes leads to the less accuracy. In my opinion, the ground truth data with the regions and layers is more descriptive then the ground truth with only layers. It would ...

Re: Dense CRF with DGM

I will be very glad if you let me know about your new results. In order to see the class probabilities for each pixel, please check the Demo Visualization project: the visualization of the “Node potential vector” is exactly what you need. The 3D version of the library would be interesting. Please fe...

Re: Dense CRF with DGM

In my opinion, the code that you attached is OK. I have used variables m and i for testing on multiple images. Since you perform testing on a single image, these variable are not needed. Please see attached the modified code. I have deleted the redundant code and added the dgm::vis::CMarker class re...

Re: Dense CRF with DGM

I have tried out your code with 5 and 36 features and could not reproduce the bug. In both cases the code produces results. I have used the latest version of the DGM library from GitHub with OpenCV v.3.3.0 . However, I think that there might be 2 reasons for the bug: ⋅  OpenCV v.3.2.0 had ...

Re: Dense CRF with DGM

The error in MessagePassing.cpp is related to the inference stage. Having the current information, you shared with me, it is difficult to say, where exactly the problem lies. It might be in the node training phase, or data preparation phase. Could you please provide some additional information, in p...

Re: Dense CRF with DGM

So, if I include serialize.h in Demo train.cpp of DGM and use "to", I can save Potential matrices in that dat format. Further I can use it in the modified version of densecrf. That is right. How long it takes to produce DGM with Denscrf? Do you mean how long will it take to implement Dens...

Re: Dense CRF with DGM

Thank you for the interest to the DGM library. I have revised the dense-CRF Code, to make it work with OpenCV and DGM library. You can download it here: https://github.com/ereator/Dense-CRF Currently I work on integrating the DGM library into the Dense-CRF. For that you Need to extract the potential...

Re: DGMLib Parameter Estimation - Questions

As I understand now, the values of the objective function may be less then 0, and you need to find its maximal value. I think, that your idea of shifting the values of the objective function will work. If it is possible to roughly estimate the theoretical boundaries of the objective function, e.g. [...
