Perception of Color Quality for Natural Images Viewed, Edited, and Printed Within the Context of a Home Digital Color Imaging System
… home environment there exits a host of digital color imaging (DCI) system configurations. The combination of devices and software at the consumer's desktop with devices and services at a remote location (e.g., Print at Kodak), creates a complex interaction of device, contextual, and observer …

Analysis of Interphase Chromatin Motion in HeLa Cells
… which modify chromatin mobility. Using dual color imaging of flourescently tagged chromatin and proliferating cell nuclear antigen (PCNA) were followed through interphase. Chromatin motion was modelled as a two dimensional random walk. Reduction in chromatin mobility was observed during S …

Spatio-temporal slope measurement of short wind waves under the influence of surface films at the Heidelberg Aeolotron
A novel, high resolution Imaging Slope Gauge (ISG) at the Heidelberg Aeolotron is presented. The instrument allows measurements of the two-dimensional slope of short wind-driven water waves at unprecedented temporal and spatial resolution. Wave number spectra are measured up to k = 13000 rad/m with …

Investigations into Ultra-Low-Power Underwater Imaging
Imaging underwater environments is crucial to advancing our understanding of marine organisms, climate change, marine geology, aquaculture farming, and underwater archaeology. Despite significant advances in underwater imaging, scalable and longterm imaging of underwater environments is still an …

A Multiple Sensors Approach to Wood Defect Detection
… e.g., a single optical sensor or an X-ray imaging system. These systems cannot detect all critical defects in wood. This research work reported in this dissertation is the first aimed at creating a vision system utilizes three imaging modalities: a color imaging system, a laser range …

Unsupervised tracking and automated analysis of multi-population neural activity under anesthesia
… datasets. By optimizing and using dual-color imaging, we recorded simultaneously the activity of excitatory neurons and subsets of inhibitory interneurons at different stages of anesthesia. The automated analysis pipeline allowed us to study the behavior of the same individual neurons …

Molecular Mechanisms of Lymphocyte Activation - Please Mind the Gap
… KS model. Functional activation assays and three-color imaging reveal a link between size-dependent phosphatase exclusion and B cell activation, providing evidence for KS as a general activation mechanism in lymphocytes. Finally, stiffness-dependent T cell activation is explored. While substrate …

Materials and Surface Processes at Gale Crater and the Moons of Mars Derived from High Spatial and Spectral Resolution Orbital Datasets
… still ~6 km north of the ridge, high resolution color imaging and low resolution spectral remote sensing data of the ridge collected by Curiosity are consistent with orbital observations. When Curiosity does arrive at the ridge, it is well equipped to distinguish between predicted end-member …

Multi-color visualization and quantification of single RNA translation and HIV-1 programmed ribosomal frameshifting in living cells
… 200 to 900 nucleotides. By employing a multi-color probe strategy, NCT shows that a small fraction (~5%) form multi-RNA sites in which two distinct RNAs are translated simultaneously while spatially overlapping. NCT was then applied to further understand the dynamics of translating RNAs …

Color image quality measures and retrieval
The focus of this dissertation is mainly on color image, especially on the images with lossy compression. Issues related to color quantization, color correction, color image retrieval and color image quality evaluation are addressed. A no-reference color image quality index is proposed. A novel …
