Learning to localize landmarks
… single point. We refer to these small objects as landmarks in addition to the more common usage of the term to refer to the anatomical or facial landmarks. Landmark localization refers to the detection of one or more such landmarks in an image. In this dissertation, we describe methods for …

Landmarks for clothing retrieval
… to solve the clothing retrieval problem using landmarks based on the clothing type and features surrounding the landmarks to get a more ingrained view of the design. We compare this method with other models most of which use the whole image as inputs and show the superiority of the model which …

Vision-Aided Navigation using Tracked Landmarks
… the algorithm leverages recognizable ‘landmarks’ in the environment, the positions of which are known in advance, to stabilize the state estimate. Measurements of the position of one or more landmarks in the image plane of a monocular camera are then filtered using an extended Kalman …

COMPUTER-BASED IDENTIFICATION OF LANDMARKS IN CEPHALOGRAMS
… was to detect and measure some craniofacial landmarks for use by the orthodontist in diagnosis and treatment planning. Altogether eight landmarks were to be detected. They were the sella, nasion, pogonion, menton, incisor superious, apicale superious, incisor inferious and apicale inferious. …

Explicit Attention to Allocentric Landmarks Improves Memory-Guided Reaching
The presence of an allocentric landmark can have both explicit (instruction-dependent) and implicit influences on reaching performance However, it is not known how the instruction itself (to rely either on egocentric versus allocentric cues) influences memory-guided reaching. Here, 13 participants …

Southern Fiction: Southern Small-Town Culture and Its Landmarks
… of the small-town culture is the significance of landmarks—both in a geographical and manmade sense. These elements and traits largely compose the small-town culture demonstrated throughout Lee Smith's <em>Oral History</em>, Olive Ann Burns's <em>Cold Sassy Tree</em>, and Candice Lawrence's short …

Word boundary detection using landmarks : a survey of consonants
… of place of articulation. By using acoustic landmarks, from which information about manner as well as durations can be easily extracted, word segmentation and/or lexical access processes can start without the complete identification of all features (such as place) for a particular segment.

Identifying facial landmarks, action units and emotions using deep networks
… Neural Networks (CNNs) to predict facial landmarks, facial action units and emotions and to study the results of intermediate experiments while doing so. Learning the different features of facial images has always been a difficult task and primarily involves using hand-crafted features …

An art gallery approach to ensuring that landmarks are distinguishable
… different classes of partially distinguishable landmarks are needed to ensure that a robot can always see a landmark without simultaneously seeing two of the same class? To study this, we introduce the chromatic art gallery problem. A guard set S ⊂ P is a set of points in a polygon P such that …

Gender Difference in Situation Awareness when Receiving Wayfinding Direction by Landmarks and Headings
<p>In aviation, situation awareness (SA) is a fundamental requirement for effective flying and air traffic control. This skill has greatly been associated with pilot and air traffic controller performance. Previous studies in aviation and other fields have shown that gender differences exist in SA …

Comics-based literary trails: the case of Tintin and the Saint-Nazaire landmarks
This thesis aims to assess whether Hall et al.’s Circuit of Culture theory and pattern are applicable to a cultural object such as a literary trail based on a comic book. The case under study is a literary trail inspired by the comic book character of Tintin in the city of Saint-Nazaire, France. It …

Detection of Stroke, Blood Vessel Landmarks, and Leptomeningeal Anastomoses in Mouse Brain Imaging
… regions to be defined relative to the brain landmarks, based on the brain's center, orientation, and scale. The method newly proposed in this paper combines stroke detection, brain coordinate system extraction, and collateral connection detection in stroke-affected mouse brains using only …

Using regions of interest to track landmarks for RGBD simultaneous localisation and mapping
… immense image data to identify and track landmarks in RGBD SLAM can be computationally expensive for smaller robots. This dissertation presents an alternate method to reduce the computational time. The proposed algorithm extracts features from a region of interest (ROI) to track landmarks …

Gender Differences in Accurate Route Recall in Novice Drivers Using Landmarks in Electronic Maps
… of route recall in traditional paper maps using landmarks. Research also suggests that what is already known about wayfinding behavior in the physical world can be applied to computer-generated environments. The goal of this study is to merge these two conclusions to determine if gender and route …

Autonomous navigation and localization of a quadrotor mini-uav by landmarks in indoor environments
… And indoor localization by using artificial landmarks in a known environment by utilizing vertical and horizontal cameras onboard of the quadrotor is proposed. The local data from the inertial measurement units onboard are combined with the proposed localization method.

Design of tool for analysis of speech development disorders using landmarks and other acoustic cues
… 2014. Feature cues, including abrupt acoustic landmarks (Stevens 2002) and other acoustic feature cues, were hand-labeled and analysis of factors that may influence feature cue modifications included position in the word, position in the syllable, word length measured in syllables, lexical …
