Building a web-based image markup system14 Feb 2014
A web-based service like Amazon Mechanical Turk needs a web-based interface for turkers to crowdsource data on fish shape. Existing software to digitize images requires a separate download, and most of it runs only on Windows. Distributing this software to hundreds of crowdsourced workers and ensuring it works on their computers can be quite a challenging task.
To that end, we’ve had to develop an image digitization interface using only technologies that work in your browser. Specifically, we use the HTML5
The elegance of using the web as a platform to drive our crowdsourcing effort is that as long as you have a way to browse the internet, you should be able to contribute your work to our research. Our interface is agnostic to technology choice: we’ve tested it on an iPad and it works quite well.
