Using a timelapse camera, scientists can track entities (such as people and wildlife) and conditions (such as weather and visibility) that occur in a particular place over time. Cameras are placed at strategic locations, where images are automatically taken at regular intervals (e.g., every 5 minutes, every hour). After collecting the camera's card, they visually examine each image and count/describe the entities and conditions of interest. The Timelapse Image Analyser helps scientists do this last visual analysis and counting step.

In brief, the tool automatically goes through all images and extracts information such as dates and times; it categorizes unusual images including dark (night time) and corrupted ones; it displays a series of 'codes' specific to the biologist's project, where the biologist can fill in codes by typing, selecting from menus or (for counting) simply by clicking on objects in the image. To help the biologist find things, it includes a magnifying glass, pan and zooming (where switching images will keep the same pan/zoom levels), as well as several image enhancement methods. All data is written to a file that can be opened in Excel.

Tutorial Manual

This step by step tutorial illustrates how to use the Timelapse Image Analyser. We recommend you download the image set (as well as the program), so you can follow along by doing the operations on the images as illustrated in the tutorial.

Download, Installation and Use

Require

  1. If you are running on your own personal computer:
    1. It should download a file called setup.exe. Select that and just follow the instructions.
    2. Start the program through your Start menu, titled Timelapse Image Analyzer, or via the Start Menu Folder Grouplab.
    3. The program will automatically check for updates every time you run it. This is really convenient, as it guarantees you are always using the most up to date version.
    • Only if it says its missing: Microsoft .NET Framework 3.5 and its | Service Pack
      The .NET Framework should be on your computer, but if the program says its missing, you can install it (and its service pack) from the above links.
  2. If you are running on an institution's computer:
    1. Download and open the zip file
    2. Extract the Timelapse.exe program to a place of your choosing (e.g., your Desktop, My Documents).
    3. To avoid confusion, delete the zip file.
    4. Start Timelapse.exe (it may just be called Timelapse) - You should see a 'Getting Started' screen with instructions.

Optional

See the New Site which replaces this one. These are needed to create and/or edit the Code Template file)

TimeLapse Quick Start:

See the New Site which replaces this one.

  1. Select Load from the program's File menu, and select the folder containing your images and the CodeTemplate.xml
  2. If you want to count something
    • click on the counter representing the thing you want to count
    • left click on the thing you want to count on the image - it will draw a marker on the image
    • right click to delete that marker
  3. The above assumes a code template file is provided to you (one is in the sample images). If you want to create your own CodeTemplate.xml file, refer to the manual above.
