Timelapse 1.0 Image Analyser

Important Note

This page and the links from it are for Timelapse 1, which has since been replaced by a new version Timelapse 2. As the new version of Timelapse 2 uses template and data files that are not compatible with Timelapse 1, it includes facilities to convert the old files into the new format. However, if you really really need to use the old version, you can still get it here.

Timelapse 1.0 (old version)

Remote cameras capture images of strategic field locations at regular intervals or when any motion is detected. After retrieving the camera's images, scientists visually examine each image and count/describe the entities and conditions of interest (e.g., people, wildlife, weather).

The problem is that visually analyzing thousands of images and encoding that data is a painful process.

Timelapse Image Analyser helps scientists do this last visual analysis and encoding step. In brief, the tool:

  • reads and displays images from any type of remote camera (as long as they are numbered);
  • automatically extracts information from all images such as dates and times;
  • categorizes unusual images including dark (night time) and corrupted ones;
  • displays an interface for entering data specific to the scientist's project, where the biologist can enter data by typing, by selecting from a list of choices, and (for counting) by clicking on objects in the image;
  • supports visual search through a magnifying glass, through pan and zooming (where switching images will keep the same pan/zoom levels), and through several image enhancement methods;
  • saves all data to a file that can be opened in Excel and later imported into a database of your choice.


Timelapse Image Analyzer was created by Saul Greenberg, a University of Calgary, Computer Science professor, and is supported by Greenberg Consulting Inc.
