Pixel Objectness

The following repository contains pretrained model for pixel objectness.

Please visit our project page for the paper and visual results.

If you use this in your research, please cite the following paper:

}

These models are freely available for research and academic purposes. However it's patent pending, so please contact us for any commercial use.

Using the pretrained models:

This model is trained using Deeplab-v1 caffe library. Please cite [1] and [2] if you use the code.

• Setup: Download and install Deeplab-v1 from here

• Refer to demo.py for step-by-step instruction on how to run the code.

• Store the images that you want to process in the images folder.

• Update the caffe binary path and image extension variable in demo.py

• Running demo.py will produce three files 1) image_list.txt : contains list of of input images, 2) output_list.txt: contains names to be used to store the output of pixel objectness 3) test.protoxt: prototxt file required for loading the pretrained model.

• Please resize your images so that the maximum side is < 513, otherwise update the crop_size value in test_template.prototxt. Bigger crop sizes require larger gpu memory.

Visualizing the results:

After execution demo.py will store pixel objectness results as matlab files.

Please refer to show_results.m to see how to visualize and extract foreground masks.
