Multimodal Image Geocoding: The 2013 RECOD's Approach
نویسندگان
چکیده
This work describes the approach used by the RECOD team in the MediaEval Placing Task of 2013, in which we were required to develop an automatic scheme to assign geographical locations to images. Our approach is multimodal, considering textual and visual descriptors, which are combined by a rank aggregation strategy. We estimate the location of test images based on the coordinates of top-ranked images in the list of combined results.

A Multimodal Approach for Video Geocoding
Developed in the context of placing task at MediaEval 2012, this work addresses the problem of automatically assigning geographical coordinates to videos. This year our group extended the implementation of our framework for multimodal geocoding for combining textual and visual descriptors. In this paper, we describe our approach and report the results for 2012 datasets.
متن کاملRECOD Working Notes for Placing Task MediaEval 2011
This work is developed in the context of placing task at MediaEval 2011. It consists in automatically assigning geographical coordinates to a set of videos. Our group proposed an architecture design for the multimodal geocoding. In this paper, we focused on implementing a simple content-based approach, which is part of the proposed framework. The reported results show our strategy compared to t...
متن کاملMultimodal medical image fusion based on Yager’s intuitionistic fuzzy sets
The objective of image fusion for medical images is to combine multiple images obtained from various sources into a single image suitable for better diagnosis. Most of the state-of-the-art image fusing technique is based on nonfuzzy sets, and the fused image so obtained lags with complementary information. Intuitionistic fuzzy sets (IFS) are determined to be more suitable for civilian, and medi...
متن کاملGeocoding and Stereoscopy of Synthetic Aperture Radar Image
This thesis is concerned with the geocoding of Synthetic Aperture Radar (SAR) images and the use of stereo SAR images. The work was carried out as part of the preparation for the launch of the ERS-1 sateffite, due in July 1991, which will carry a SAR sensor. There are two basic approaches to geocoding: image-to-object and object-to-image. Both of these methods have been analysed and assessed on...
متن کاملCapacitated Multimodal Structure of a Green Supply Chain Network Considering Multiple Objectives
In this paper, a supply chain network design problem is explained which contains environmental concerns in arcs and nodes of network. It is assumed that there are some routes such as road, rail and etc. in each pair of nodes. In this model decision variables are choosing facilities to open, environmental investment level in each facility and flow of products between nodes in each route. A multi...
