An Exploratory Study of Human Performance in Image Geolocation Tasks
نویسندگان
چکیده
Identifying the precise location where a photo was taken is an important task in domains ranging from journalism to counter-terrorism. Yet, geolocation of arbitrary images is difficult for computer vision techniques and time-consuming for expert analysts. Understanding how humans perform geolocation can suggest rich opportunities for improvement, but little is known about their processes. This paper presents an exploratory study of image geolocation tasks performed by novice and expert humans on a diverse image dataset we developed. Our findings include a model of sensemaking strategies, a taxonomy of image clues, and key challenges and design ideas for image sensemaking and crowdsourcing.

The Development and Standardization of an Indian Positive Body Image Scale with an Exploratory Research Design
Background: Body image is an integral component of the self-concept that significantly shapes human functioning and people’s life outcomes. Although negative body image is well-studied, there is little research on positive body image. The study examined the basic characteristics of positive body image intending to standardize a scale for it. Methods: The study used using an exploratory resear...
متن کاملPreliminary Exploration of the Use of Geographical Information for Content-based Geo-tagging of Social Video
Estimating the geo-location of an image or video is an interesting and challenging task in information retrieval and computer vision. In this paper, a pure image content based approach for this task is described. We partition the world map into regions based on external data sources (climate and biomes data). We hypothesize that such a partition yields regions of high visual stability, which in...

متن کاملOptimizing Content-Based Image Retrieval for Geolocation Estimation
The prediction of geo-graphical location at which an image is taken is drawing increasing attention in recent research. However, one major limitation of most current research is that it focuses mostly on improving the geolocation prediction performance while ignoring the problem of index size, which is helpful in saving storage space. Traditional image retrieval index reduction approach can be ...
