Landmark localisation in 3D face data
Accurate landmark localisation is an essential precursor to many 3D face processing algorithms but, as yet, there is a lack of convincing solutions that work well over a wide range of head poses. In this thesis, an investigation to localise facial landmarks from 3D images is presented, without …

Visibility analysis of landmark-based navigation
… gallery problem asks for the minimum number of landmark classes required to ensure that every point in an input polygon sees at least one landmark but sees no more than one landmark of any particular class. The problem is motivated by partially distinguishable landmark-based navigation. A robot …

Consonant landmark detection for speech recognition
… in the speech signal, which constitute landmarks for consonant sounds. Because a large amount of phonetic information is concentrated near acoustic discontinuities, more focused speech analysis and recognition can be performed based on the landmarks. Three types of consonant landmarks …

Localization of robot and landmark with indistinguishability
We research localization problems with robots and landmarks related to the aspect of indistinguishability in multi-dimensional spaces. With the initial position ranges for the robot and landmarks using specific measurement models, we develop a general algorithm for minimizing the position ranges …

Image Retrieval using Landmark Indexing for Indoor Navigation
… numbers they appear in. This method is named landmark indexing. Unlike some state-of-the-art approaches, the proposed method does not need to consider large image adjacency graphs because the overlap of the images in the map sufficiently increases information gain, and mapping of similar …

Robust and reliable facial landmark detection under challenging conditions
Facial landmark detection is crucial technology for many downstream tasks, such as talking head, face editing, facial emotion recognition and face recognition. Despite the recent progress brought by deep learning, there are still many challenges in this field that render the robustness of …

The Ordinance Project: Commemorating Kansas City's LGBTQ Landmark Legislation
… with us. The efforts taken to commemorate this landmark achievement in Kansas City’s history resulted in a large body of original research and several academically rigorous projects designed to inform and engage the public through a wide variety of mediums: an oral history project, a …

Forgotten landmark: the Municipal Auditorium of Kansas City, Missouri
The Municipal Auditorium is a grand civic building in downtown Kansas City, Missouri, which encompasses venues for theater, music and athletics. Designed by Gentry, Voskamp, and Neville, and associated architects, Hoit, Price, and Barnes, and built between 1933-1936 during the Depression, the …

Processing Methods for the Detection of Landmark Acoustic Cues
… acoustic cues in the speech signal such as Landmarks, which are abrupt changes in the spectrum due to articulatory events associated with vowels and consonants. It provides an organized process that can easily be repeated and modified to be able to create an accurate and efficient detection …

Landmark : towards and alternative testing range, Vieques, Puerto Rico
… worth preserving and what is worth destroying? Landmark is a working concept as well as an artistic proposition which considers the multiple and complex ways in which land is marked. Focusing on the contested United States Navy Training Facilities in Vieques, Puerto Rico, Landmark: Towards an …

Automatic Detection of Landmark Acoustic Cues in Human Speech
… for the automatic detection of the eight landmark acoustic cues in human speech. Landmarks are key articulatory events, produced as a result of minimal vocal tract constriction (e.g., vowels and glides) or closures and releases in the oral region (e.g., nasal, fricative, and stop …

Vision-Aided Navigation for GPS-Denied Environments Using Landmark Feature Identification
… this thesis entails defining a set of inertial landmarks, the locations of which are known within the environment, and employing image processing algorithms to detect these landmarks in image frames collected from an onboard monocular camera. These vision-based landmark measurements effectively …

A framework for automated landmark recognition in community contributed image corpora
… of rich and accurate tags for images with landmarks as the main object. This framework uses state of the art computer vision techniques fused with the wide range of contextual information that is available with community contributed imagery. Images are organised into clusters based on image …

The use of landmark-based wayfinding strategies across the adult lifespan
Individuals can employ different landmark-based wayfinding strategies to acquire spatial knowledge and support navigation. Allocentric strategy use is associated with a cognitive representation of a learned environment that allows flexible navigation, while egocentric strategy use is associated …

Acoustic landmark detection and segmentation using the McAulay-Quatieri Sinusoidal Model
The current method for phonetic landmark detection in the Spoken Language Systems Group at MIT is performed by SUMMIT, a segment-based speech recognition system. Under noisy conditions the system's segmentation algorithm has difficulty distinguishing between noise and speech components and often …

Three-dimensional image analysis for quantification of tooth movements and landmark changes
… procedure includes image reconstruction, landmarks identification, coordinate system setup, superimposition, and displacement or change calculation. The specified procedures for maxillary teeth displacements and anatomical landmarks movements were presented and validated. The validation …

An analysis of SIFT object recognition with an emphasis on landmark detection
… of feature-based object. recognition applied to landmark detection. I have built a system using SIFT object recognition and Locality-Sensitive Hashing to quickly and accurately detect landmarks with accuracies ranging from 85-95%. I have also compared PCA-SIFT, a newly developed feature …
