Image collection optimization in the design and operation of lightweight, low areal-density space telescopes
Demand for space imagery has increased dramatically over the past several decades. Scientific and government agencies rely on Earth-observing space assets for a variety of functions, including mapping, agriculture, and intelligence. In recent years, online interactive mapping services have created …

Surface Levels
… abstract at a visible level. This abstract 3D/2D image collection is translated into material expressions using acrylic sheets, acrylic ink, and wood as the main media for construction of individual works. Collectively, they serve to make the invisible visible.</p>

Reagents for infrared chemical imaging of fingerprints on difficult surfaces
… FTIR chemical imaging involves the simultaneous collection of thousands of mid-infrared spectra across a sample using a focal plane array (FPA) detector. This allows for the collection of chemically specific spectral data while maintaining spatial information. Images can then be generated based …

View synthesis for kinetic depth X-ray imaging
… of feature based synthesis of transmission X-ray images. The synthetic imagery is formed through matching and morphing or warping line-scan format images produced by a novel multi-view X-ray machine. In this way video type sequences, which periodically alternate between synthetic and detector …

Analysis and evaluation of visual information systems performance
… information retrieval from generic photographic collections. The development of visual information retrieval systems has long been hindered by the lack of standardised benchmarks. Researchers have proposed numerous systems and techniques, and although different systems clearly have their …

Organising and structuring a visual diary using visual interest point detectors
… example of one such device. The vast quantity of images generated by these devices means that the management and organisation of these collections is not a trivial matter. We believe wearable cameras, such as SenseCam, will become more popular in the future and the management of the volume of data …

Expanding commonsense knowledge bases by learning from image tags
… bases by using the metadata of large online image collections. Online image collections present a source of knowledge that is supported by many contributors, has good representation of objects and their properties, and is visual. The collection's broad support of objects and object properties …

Remote Vibration Estimation Using Displaced Phase Center Antenna SAR in a Strong Clutter Environment
… SAR produces a high resolution, two-dimensional image of a scene of interest. An underlying assumption when creating this high resolution image is that all targets in the ground scene are stationary throughout the duration of the image collection. If a target is not static, but instead vibrating, …

Automated High-quality Image Acquisition for UAV-enabled Bridge Visual Inspection
… in GPS-denied bridge areas, and potential image quality issues. These challenges hinder the widespread adoption of UAVs in real bridge inspection. This study aims to establish a systematic framework for enabling UAVs to automatically capture high-quality images of bridges, thereby …

Towards vision based robots for monitoring built environments
… if we can simplify or automate visual data collection, monitoring, and analysis. In this work, we focus specifically on improving autonomous image collection, building 3D models from the images, and recognizing materials for progress monitoring using the images and 3D models. Image capture …

Event-centric Twitter photo summarization
… on spectral geometry that summarize a photo collection into a small subset that represents the collection well. While the definition for a good summarization might not be unique, we focus on two metrics in this thesis: representativeness and diversity. By representativeness we mean that the …

RELEVANCE FEEDBACK TECHNIQUES FOR CONTENT-BASED IMAGE RETRIEVAL
… In particular, without detailed knowledge of the collection make-up and retrieval environment, most users find it difficult to formulate queries that are well designed for retrieval purposes. Another problem is that if the query representation used is low level, the initial retrieval may not be …

Development of an innovative and efficient urban vegetation monitoring system for sustainable urban ecology
… using deep learning technology. Extensive data collection, preprocessing, and training were key components of this research. Image collection routes were meticulously planned to ensure a comprehensive dataset representing diverse urban vegetation. A major challenge was the quality and privacy …
