Photo-Realistic Scene Modeling and Visualization using Online Photo Collections
Reconstructing 3D scenes from online photo collections has attracted a tremendous amount of interest from both academia and industry. The progress in the past decade has been exceptional, in terms of scale and reconstruction quality. Yet, we are still far from creating 3D models that support …

Metal Complex Photo-activators for the Time-Controlled, Photo-Oxidation of Polyolefins
The use of antioxidant photo-activator (APA), which is based on a combination of a photo-activator (ideal, e.g., iron dialkyldithiocarbamate (FDMC) and conventional, e.g., iron acetylacetonate (FAcAc)) and U.V. stabilizer, has been examined in both low-density polyethylene (LDPE) and polypropylene …

[Ru-POM] Photo-electrocatalysis
In the past years, photo-sensitation of polyoxometalate anions with Ruthenium polypyridyl cations has received intensive investigation as the excellent photoluminescence properties and stability of Ruthenium polypyridyl complexes in multiple redox states can be coupled to the POM in order to extend …

Photo-produced phonons in semiconductors
… of phonon imaging are used in conjunction with photoluminescence measurements to determine the characteristics of optically generated phonon sources in Si, Ge and GaAs at 1.7K. Focused-laser excitation of a semiconductor generates phonons as a byproduct of electronic excitation. A single carrier …

Event-centric Twitter photo summarization
… based 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 …

Metaphotographs: On represnting digital photo collections
Photos are an important means of sharing and reviewing personal history. As an individual act, photo browsing contributes to the formation and reinforcement of personal identity. As a social act, such as a visual aid for storytelling, it deepens social ties by introducing new personal information …

Photo annotation and retrieval through speech
… annotation and retrieval system for digital photographs. The system uses a client/server architecture which allows photographs to be captured and annotated on various clients, such as mobile camera phones or the web, and then processed, indexed and stored on networked servers. For …

Photo-responsive liquid crystal block copolymers/
Photo-responsive liquid crystal polymers (LCP) which contain azobenzene moieties have gained interest for their ability to change properties by merely irradiating them with the correct wavelength of light in the appropriate temperature range. Furthermore, they have been crosslinked for elasticity …

Children’s perceptions of occupation within a trauma-capable therapeutic programme: A photo voice and photo elicitation study
… collection periods. Creative methods, including photo-voice and photo-elicitation, were employed alongside semi-structured interviews, which were audio-recorded and transcribed. The six-phased process of reflexive thematic analysis (Braun & Clarke, 2022) was used to analyse the data. Three main …

Evaluation of a domestic photo sharing environment
… so as to maximise the interaction possibilities. Photographs are a very affective and efficient way of connecting people to each other. We should not forget the social role photographs have to play. The most important aspect of the picture is the story that it is trying to convey, the people in …
