From Captions to Visual Concepts and Back

Code for detecting visual concepts in images.

Installation Instructions

  1. Create directory, checkout code, caffe, coco-hooks
git clone code
git clone code/coco
cd code/coco
git checkout 3736a0068b6e4634563b0c5847d7783dae9bd461
cd ../../
  1. Make caffe and pycaffe
git clone code/caffe 
cd code/caffe 
git checkout mil
make -j 16
make pycaffe
cd ../../
  1. Get the COCO images, caffe imagenet models, pretrained models on COCO.
# Get the COCO splits, ground truth
wget && tar -xf data.tgz

# Get the COCO images
cd code

# Download and unzip the images 
bash scripts/

# The code assumes images to be stored heirarchically. 
# This python scripts does the required copying.
PYTHONPATH='.' python scripts/

# Get the caffe imagenet models 
wget && tar -xf caffe-data.tgz

# Get the pretrained models. The precomputed results in the previous tarball
# were not complete. v2 tar ball fixes this.
wget && tar -xf trained-coco.v2.tgz
