This paper introduces methods for automatic annotation of landmark photographs via learning textual tags and visual features of landmarks from landmark photographs that are appropriately location-tagged from social media. By analyzing spatial distributions of text tags from Flickr’s geotagged photos, we identify thousands of tags that likely refer to landmarks. Further verification by utilizing...

This paper presents a novel landmark-based shape deformation method. This method effectively solves two problems inherent in landmark-based shape deformation: (a) identification of landmark points from a given input image, and (b) regularized deformation of the shape of an object defined in a template. The second problem is solved using a new constrained support vector machine (SVM) regression ...

One important problem in the human brain mapping research is to locate the important anatomical features. Anatomical features on the cortical surface are usually represented by landmark curves, called sulci/gyri curves. These landmark curves are important information for neuroscientists to study brain disease and to match different cortical surfaces. Manual labelling of these landmark curves is...

We investigated the echolocating bat's use of an acoustic landmark for orientation in a complex environment with no visual information. Three bats of the species Eptesicus fuscus were trained to fly through a hole in a mist net to receive a food reward on the other side. In all experiments, the vocal behavior of the bats was recorded simultaneously using a high-speed video recording system, all...

Correct positioning of polarity axis in response to internal or external cues is central to cellular morphogenesis and cell fate determination. In the budding yeast Saccharomyces cerevisiae, Bud3p plays a key role in the axial bud-site selection (axial budding) process in which cells assemble the new bud next to the preceding cell division site. Bud3p is thought to act as a component of a spati...

Following the footsteps of most other states, Massachusetts opened its Office of Patient Protection in January 2001. Established under what the media hailed as a “landmark” patients’ bill of rights, the Massachusetts legislature created a state agency empowered to review medical decisions made by health maintenance organizations (HMOs) that are challenged by patients. However, after opening its...

Successful wayfinding requires accurate encoding of two types of information: landmarks and the spatial relations between them (e.g. landmark X is left/north of Y). Although both types of information are crucial to wayfinding, behavioral and neurological evidence suggest that they have different substrates. In this paper, we consider the nature of the difference by examining comprehension times...

It is not known how egocentric visual information (location of a target relative to the self) and allocentric visual information (location of a target relative to external landmarks) are integrated to form reach plans. Based on behavioral data from rodents and humans we hypothesized that the degree of stability in visual landmarks would influence the relative weighting. Furthermore, based on nu...

BACKGROUND Lumbar puncture (LP) is an essential procedure in the diagnosis and treatment of several critical situations. This procedure is routinely performed by palpating external landmarks to find the most appropriate inter-spinous space. In the current study, we compared surface landmark and ultrasound (US) guided LP in different aspects. MATERIALS AND METHODS This clinical trial study was...
