Relationship of this project to the Latent SVM module in OpenCV about voc-dpm HOT 4 CLOSED

@davidwe, I'm not involved in the OpenCV DPM implementation and don't know much about it, so unfortunately I can't provide many useful answers. My impression (which could be wrong, outdated, or both) is that the OpenCV implementation only supports detection using pre-trained models from an old version of the DPM code (release3, perhaps). If you find more details, feel free to post them here.

I found this script: https://github.com/Itseez/opencv_extra/blob/master/testdata/cv/latentsvmdetector/mat2xml.m from July 2012.

Were there changes in the format of the model file between voc-dpm versions?

from voc-dpm.

Yes, it seems.

mat2xml('./FooBar_final.mat', 'FooBar_final.xml')
Reference to non-existent field 'rootfilters'.

Error in mat2xml (line 5)
for i = 1:length(model.rootfilters)

Can this script be adapted to match the new model format or has the detection alogrithm to be updated too in this case?

from voc-dpm.

Judging from code you pasted, that script was written to convert models from release3. The differences in model format (and detection algorithm) between release3 and {4,5} are quite significant. It will not be a simple job of tweaking that script.

If you're simply looking for a faster C or C++ implementation of DPM, then I recommend checking out the code that can be found here: http://charles.dubout.ch/en/coding.html.
