3-D Reconstruction of Multi-object Scenes from Multiple Images
… of research into reconstructing 3-D models from images has concentrated on the case of single objects. This thesis presents a method to model complex multi-object scenes in a series of steps starting with a set of images which surround a scene and ?nally producing a complete photorealistic …

Estimating True Object Color from a Single Image and Multiple Images
… to variations in the object’s color in different images captured under varying illuminations at different viewpoints. A number of methods have been developed to find true object color, which is independent of illuminations and viewpoints. In this dissertation, we will address the problems of color …

A study on image change detection methods for multiple images of the same scene acquired by a mobile camera.
… of change while reducing unimportant changes in multiple outdoor images of the same scene containing fence wires (i.e., a chain-link mesh fence) acquired by a mobile camera from slightly different viewing positions, angles and at different times is a very difficult problem. Regions of change …

Medical Image Registration Using Artificial Neural Network
… is the transformation of different sets of images into one coordinate system in order to align and overlay multiple images. Image registration is used in many fields such as medical imaging, remote sensing, and computer vision. It is very important in medical research, where multiple images …

Nature Orchestrated
… is about my recreation of nature by combining multiple images to create a completely different result. Picking and choosing the most meaningful elements to emphasize gives me the ability to create a differently organized reality.</p>

STRONG GRAVITATIONAL LENSING MODELLING OF GALAXY CLUSTERS IN THE ERA OF BIG DATA
… observations, revealing a number of multiple images and substructures greater than previously unknown, and thus enabling lens models of unprecedented accuracy. The synergy between these observatories will drastically improve the number of currently known SL systems and significantly …

Burst Imaging with Learned Continuous Kernels
… imaging is a technique that consists of taking multiple images in quick succession and merging them into one output image. By aligning and combining data from multiple frames, we can increase resolution, attenuate noise, reduce motion blur and expand the dynamic range to obtain a higher quality …

Gravitational Lensing and the Maximum Number of Images
… tool. The ability of a lensing system to produce multiple images of a luminous source is one of the aspects of gravitational lensing that is exploited both theoretically and observationally to improve our understanding of the Universe. In this thesis, within the field of multiple imaging we …

Image enhancement methods and applications in computational photography
… (DOF) and dynamic range than any of the input images. In this dissertation, I also investigate super-resolution image restoration from multiple images, which are possibly degraded by large motion blur. The proposed algorithm combines the super-resolution problem and blind image deblurring …

Detailed and Practical 3D Reconstruction with Advanced Photometric Stereo Modelling
… Stereo (PS), which operates by capturing multiple images under changing illumination has traditionally been one of the most successful techniques at recovering a large amount of surface details, by exploiting the relationship between shading and local shape. However, using PS has been …

Computational photography with novel camera sensors
… pixel design. It is shown that recording multiple images with a sensor of asymmetric sub-pixel layout increases the spatial sampling capability compared to a conventional sensor. Both proposed camera designs are the combination of novel imaging sensors and image recovering algorithms. …

The Church as a Theophanic Community
The Vatican II document, Lumen Gentium, holds multiple images of the Church in tension and was greatly informed by two ecclesiological models: The Church as Sacrament and eucharistic ecclesiology. This thesis explores the Church as a community of theophany as a model that is not only in harmony …

VIP: Finding Important People in Images
… are the most important individuals in it? Given multiple images of a person, which image depicts the person in the most important role? We introduce a measure of importance of people in images and investigate the correlation between importance and visual saliency. We find that not only can we …

Research on 3D reconstruction based on 2D face images.
… relies on large image scanning equipment to fuse multiple images through sensors for 3D face reconstruction. However, this approach requires manual modelling, which is costly in terms of time and money, and expensive in terms of equipment, making it unpopular in practical applications. Compared to …

Multi-spectrum field-use image capture & analysis and the RIBG image filter
… for the creation of traditional 3 channel RGB images from the 4 channel RIBG image. The infrared information is applicable to field capture and analysis because it: (1) limits visual scene disturbance at time of capture, (2) generates multiple images from a single captured image and (3) and …

A new degenerate Fermi gas apparatus
… of the machine. The system relies on taking multiple images with time scale shorter than typical vibration periods. Third, a new experiment control system is developed. The new control system replaced the outdated 8 years old control system by providing us with more channels and speed, …

3D reconstruction from 2D images and applications to cell cytoskeleton
… three dimensional (3D) reconstruction from 2D images can be grouped into two categories: computer-vision-based reconstruction and tomographic reconstruction. By exploring both the differences and connections between these two types of reconstruction, the thesis attempts to develop a new …

Multi-item memory in the primate prefrontal cortex
The ability to retain multiple items in short-term memory is fundamental for cognition, yet almost nothing is known about its neural basis. To explore the mechanisms underlying this ability, we trained two monkeys to remember a sequence of two images across a short delay. We then recorded the …

Semantic Mapping of Road Scenes
… a solution to generate a dense semantic map from multiple street-level images. This map can be imagined as the bird’s eye view of the region with associated semantic labels for ten’s of kilometres of street level data. We generate the overhead semantic view from street level images. This is in …
