DISA at ImageCLEF 2014 Revised: Search-based Image Annotation with DeCAF Features

TL;DR

This paper describes an improved image annotation system using DeCAF features and a new similarity search component, analyzing how search parameters affect annotation quality in the ImageCLEF 2014 challenge.

Contribution

Introduction of a new similarity search component integrated with DeCAF features for enhanced image annotation performance.

Findings

The new similarity search component improved annotation accuracy.

Different similarity search parameters significantly influence annotation quality.

System achieved competitive results in the ImageCLEF 2014 task.

Abstract

This paper constitutes an extension to the report on DISA-MU team participation in the ImageCLEF 2014 Scalable Concept Image Annotation Task as published in [3]. Specifically, we introduce a new similarity search component that was implemented into the system, report on the results achieved by utilizing this component, and analyze the influence of different similarity search parameters on the annotation quality.
