Dynamic Spatial Verification for Large-Scale Object-Level Image Retrieval
[article]
2019
arXiv
pre-print
Preserved Fulltext
Other Versions
We propose a new approach for spatial verification that aims at modeling object-level regions dynamically clustering keypoints in a 2D Hough space, which are then used to accurately weight small contributing ...
For instance, hidden people, spliced objects, and subtly altered scenes can be difficult for a user to detect initially in a meme image, but may contribute significantly to its composition. ...
In this paper we propose a new solution for spatial verification in image retrieval that supports these tasks by modeling object-level regions with the goal of retrieving the sources of small regions in ...
