Timelapse

Camera traps, remote cameras, field cameras and wildlife cameras are cameras strategically located in the field. They all capture activity at the camera’s location over time. Each camera automatically takes an image or video at pre-set time intervals or through motion triggering. A set of cameras can easily collect thousands to millions of images.

The analyst’s task. After retrieving the cameras’ contents, analysts visually examine each image or video to turn it into data. Ecologists, for example, count and describe wildlife in the scene and conditions of interest (e.g., people, wildlife, weather).

The problem is that visually analyzing and encoding data from this multitude of images and videos is a painful process.

Timelapse is a free software application that helps scientists do this last visual analysis and encoding step as efficiently as possible. 

What Timelapse offers

You define your own custom data fields to turn your images to the data you need.
Your images can be jpeg or video files or both
You add images as they are collected over time from any remote camera; Timelapse automatically extracts file information including dates, file names and file location.
You automatically populate your fields with image metadata of your choosing.
You efficiently inspect images through rapid image navigation, by viewing multiple images at a time, by examining details using zooming or a magnifying glass, by image enhancement, and others.
You tailor your own efficient workflow by mixing and matching the many Timelapse facilities supporting bulk and repetitive data entry.
You can select, view and work on subsets of your images by a simple query dialog.
You use image recognition to see and select subsets of recognized entities, including identifying empty images.
Coming soon: image recognition for video including bounding boxes!
You identify episodes of activity by setting a time interval, where TImelapse automatically groups those images together.
You export data to csv files that can be opened by other applications for data analysis, such as Excel, R, or a system of your choice.
Internet connectivity is not required to run Timelapse. You install and use it as a local application on your own computer.
And it won’t cost you a cent.
