In this project, we developed a hybrid approach for verifying multimedia use on Twitter. This work converged into the manuscrit available at this link and presented at MediaEval 2016.
The project contains below main parts:
-
Image_Forensics: extract forensic features from images in development set and test set.
-
Text_Retrieval: perform google image reverse search and extract relevant websites containing images similar to the query image. To videos, extract users' comments from Youtube.
-
Textual_Feature: extract useful textual features from text retrieved in part 2.
-
Tweet features: from a user's post, extract post-based and user-based features.
