Helix

Understanding the 1,000 words of a picture





Online Social Networks (OSNs) are populated with billions of images

With more than 350 million images being uploaded daily on Facebook itself, extracting meaningful content from images has become more important that ever. As a preliminary step towards understanding and interpreting image content from a human perspective, we propose Helix, a system that tries to extract some meaningful, human understandable features from an image. Helix summarizes an image with the following: sentiment of the image, sentiment of faces present in the image (if any), and a text label for the image. These features can be used by researchers for image coding, categorization and summarization tasks on a large scale, which are currently carried out manually through human annotation.





We offer an API as well HelixAPI.

Our API provides the following endpoints:
