Geotagged photos of users on social media sites provide abundant location-based data, which can be exploited for various location-based services, such as travel recommendation. In this paper, we propose a novel approach to a new application, i.e., personalized landmark recommendation based on users’ geotagged photos. We formulate the landmark recommendation task as a collaborative filtering pro...

This article focuses on feature-based underwater localization and navigation for autonomous vehicles (AUVs) using 2D imaging sonar measurements. The sparsity of acoustic features the loss elevation angle in images may introduce wrong feature matches or insufficient optimization-based (i.e. under-constrained/degeneracy cases). motivates us to propose a novel inertial-aided sliding window optimiz...

The effect of a large stationary landmark on memory for the location of a smaller moving target was examined. Forward displacement of the target was larger when the target moved toward the landmark than when it moved away from the landmark. Target size and direction of motion also influenced displacement. When the target passed close by the landmark, forward displacement of the target was large...

When navigating by path integration, knowledge of one’s position becomes increasingly uncertain as one walks from a known location. This uncertainty decreases if one perceives a known landmark location nearby. We hypothesized that remembering landmarks might serve a similar purpose for path integration as directly perceiving them. If this is true, walking near a remembered landmark location sho...

Mobile navigation systems are important assets for travelers visiting foreign environments, as they provide instructions on how to find the way to get to a chosen destination. Research has shown that finding ones way in a foreign environment is primarily based on cues in the environment. In this paper, we propose an algorithm that generates the clearest route in terms of spatial references and ...

background evaluation of the craniofacial bones is the oldest method to measure the facial proportion ratio in orthodontics. objectives the purpose of this study was to evaluate the effect of emboss enhancement on the reliability of landmark identification in digital lateral cephalometric images. materials and methods ten digital lateral cephalograms were selected from the archive of an oral an...
