Sketch Token Toolbox V0.95

This software package provides tools to extract contour-based mid-level features, and to extract contour segmentations from images. This tool is highly efficient in speed while maintains high accuracy in contour detection. Also, [1] shows that extracted mid-level features provide additional information for object and pedestrian detections.

Installation

  1. Download Piotr's Image & Video Matlab Toolbox (http://vision.ucsd.edu/~pdollar/toolbox/doc/)
    SketchTokens/toolbox/ should have channels, classify, filters, images, matlab, etc,.
  2. Download Berkeley Segmentation Data Set and Benchmarks 500 (http://www.eecs.berkeley.edu/Research/Projects/CS/vision/grouping/resources.html)
    SketchTokens/data/BSR/ should have BSDS500, bench, and documentation.
  3. Pre-trained models can be downloaded from: http://people.csail.mit.edu/lim/lzd_cvpr2013/st_data.tgz
  4. Look up stDemo.m for how to train and test our code
