hi, I tried this code but I continue receive this error:
Extracting CNN features for surface normals of depth images...

Error in main (line 103)

What I'm supposed to do?

Hi, first you need to install MatConvNet toolbox, which requires a proper C/C++ compiler, please check the below link for installation about MatConvNet:
https://www.vlfeat.org/matconvnet/quick/
If you are able to extact CNN features, then, there should not be any problem on RNN part.
Please debug the code step by step to see the problems.
