Qu makes use and extends MATLAB’s Image Processing Toolbox to address the needs of scientists in the field of biomedical research. It allows the visualization and analysis of 4D (XYZT) datasets with any number of color channels. It allows the loading of several microscopy formats and offers a consistent API to handle the image data, the metadata, and the results of the analyses associated to the data. Qu allows extended interactivity in the form of several objects. Primary and derived data are stored in a “Qu project”, a container class that can be saved to disk and reloaded later to continue the analysis from where it was left.

Qu at a glance

  • Qu is a generic image processing package with enhanced processing functions;
  • Qu supports several microscopy formats thanks to the LOCI bio-formats library;
  • Qu offers a connection to Bitplane's Imaris through ImarisXT (commercial, Windows only);
  • Qu is easily expandable through API and plugins mechanism (in development);
  • Qu can be run on Windows 32/64 bit and Linux 32/64 bit and MacOSX 64 bit (Update: Jonas Dorn contributed compiled libraries for MacOSX). For all other platforms supported by MATLAB, only the compilation of a few C++ libraries is required.
  • Qu is open source (see License);
  • Qu has a good API documentation
  • Qu requires MATLAB 7 (R14) or above.
