UV Parameterization for Template Shape

Do this if you need to create a UV parameterization for a new object class. Below the process is highlighted for the class car. For classes bird, car, horse, sheep, cow, zebra the uv parametrization exists in the cachedir

CSM_ROOT=/home/nileshk/csm_root/

cd  $CSM_ROOT/csm/preprocess/meshdeform/

Please edit the startup.m file with correct class_name and output_map_file.

output_map_file='/home/nileshk/CorrespNet/csm_root/csm/cachedir/downloaded_models/car/car_mapping.mat'
class_name='car'

Now create mapping from uv to face ids.

python uv_to_vertex_map.py $CSM_ROOT/csm/cachedir/downloaded_models/car/car_mapping.mat  $CSM_ROOT/csm/csm/cachedir/shapenet/car/shape.mat  $CSM_ROOT/csm/csm/cachedir/downloaded_models/car/transform.mat

We filtered images from ImageNet which were occuluded and truncated. Those annotations are in *_quality.json file. Edit imageNetDir and sysnetId with the appropriate values.
