Download Workflow

This is a sample Workflow based on an Image Mining Web Service developed in the context of e-LICO project (www.e-lico.eu). It demonstrates the main functionality of the Web Service, involving the application of several basic image operators on angiogenic images and then performing useful feature (e.g., image texture, vessel length, branch count, etc.) extraction.

Revision comment:

This version of the workflow accepts any angiogenic image (in JPG format) from users as input. Credits on myGrid team for helping with the file upload feature.
