Experimental image mining using OpenCV

Attempting to build tools to mine interesting data from large collections of scanned images

Current

• bin/locate-thumbnail:

  • Reconstructing thumbnails using OpenCV:
  • Upgrading Image Thumbnails… Or How to Fill a Large Display Without Your Content Team Quitting

• bin/extract-figures:

  • locate interesting non-text elements (images, figures, tables, etc.) on scanned book pages

Prerequisites

• Python 2.6+
• OpenCV 2.4+
• numpy

Using Mac Homebrew this should install cleanly:

brew install python numpy opencv

On Ubuntu 12.04 Precise the following is known to work - note the need for a PPA to get OpenCV 2.4+:

sudo add-apt-repository ppa:alexei.colin/opencv
sudo apt-get update
sudo apt-get install python-numpy python-opencv
