Abstract (sommario):
This thesis represents the first dedicated study of the application of computational photography in marine science. It deals chiefly with the acquisition and use of photogrammetrically derived 3D organism models. The use of 3D models as 'virtual specimens' means that they may be securely archived and are accessible by anyone in any part of the world. Interactive 3D objects enhance learning by engaging the viewer in a participatory manner, and can help to clarify features that are unclear in photographs or diagrams. Measurements may be taken from these models for morphometric work, either manua

Abstract (sommario):
This thesis documents a body of research that links the field of electro-acoustic diffusion and spatialisation with practice in the music and film post-production industries. Three research questions are posed: "How can the physical user-interfaces used for panning by the music and film post-production industries offer creative alternatives to the fader-based hardware approach commonly used for electro-acoustic performance?" "How can a Digital Audio Workstation (DAW) be used as an alternative to dedicated panning hardware? "How can emerging programming technologies offer creative alternatives

A camera calibration procedure corresponds to determine the digital geometric and optical characteristics of the camera from a known initial data set. This problem can be divided into three steps: a) acquisition of initial data; b) calibration process itself; and c) optimization.

For this aim, the presented system allows the personalization of each calibration step.

This thesis describes a system that allows users to to perform full three-dimensional manipulations to objects in photographs. Cameras and photo-editing tools have contributed to the explosion in creative content by democratizing the process of creating visual realizations of users’ imaginations. However, shooting photographs using a camera is constrained by real-world physics, while existing photo-editing software is largely restricted to the 2D plane of the image. 3D object edits, intuitive to humans, are simply not possible in photo-editing software.

All communication with the PIC and the computer is made over USB. The camera shutters are synchronized so it is possible to take pictures of moving objects at a distance of 2.5 m or more.

Vast collections of historical photographs are being digitally archived and placed online, providing an objective record of the last two centuries that remains largely untapped.

In particular, our goal is to use computer vision techniques to tie together a large set of historical photographs of a given city into a consistent 4D model of the city: a 3D model wi

Abstract (sommario):
While modern digital cameras incorporate sophisticated engineering, in terms of their core functionality, cameras have changed remarkably little in more than a hundred years. In particular, from a given viewpoint, conventional photography essentially remains limited to manipulating a basic set of controls: exposure time, focus setting, and aperture setting. In this dissertation we present three new methods in this domain, each based on capturing multiple photos with different camera settings. In each case, we show how defocus can be exploited to achieve different goals, extending what is poss

However, comparing with the “pop out” 3D image in the direct viewing angle presented by the flat panel display and movie, the fantastic “floating” 3D image which allows people to perceive and interact with in the sci-fi movie is more and more attractive. Therefore, the floating 3D image is undoubtedly the brand new landmark of the display technology in the next generation. To achieve the

Abstract (sommario):
The Enigma of Appearances is an examination into the medium of three-dimensional photography, with particular focus on the technique of stereoscopy. Invented in the mid-Victorian era, stereoscopy was an attempt to simulate natural three-dimensional perception via a combination of optics, neurology, and a pair of dissimilar images. Whilst successful in producing a powerful illusion of spatial depth and tangibility, the illusion produced by stereoscopy is anything but ??natural??, when compared to three-dimensional perception observed with the naked eye. Rather, stereoscopic photography creates

Abstract (sommario):
Humans can perceive three dimension, our world is three dimensional and it is becoming increasingly digital too. We have the need to capture and preserve our existence in digital means perhaps due to our own mortality. We have also the need to reproduce objects or create small identical objects to prototype, test or study them. Some objects have been lost through time and are only accessible through old photographs. With robust model generation from photographs we can use one of the biggest human data sets and reproduce real world objects digitally and physically with printers. What is

No prior knowledge about the scene is needed to build the 3D models. All information such as camera pose and orientation will be estimated through the processes. Therefore, this system offers a high degree of flexibility when taking photographs. The only constraint is that the intrinsic camera parameters need to be obtained first. 　The 3D modeling task is decomposed into 4 successive steps. The ca

Abstract (sommario):
Recent research has enabled reconstruction of a scene from multiple images. These algorithms rely on assumptions that the scene does not change drastically from one photo to the next. Construction photographs, in particular, pose challenges for the existing algorithms. I propose a novel image-based reconstruction algorithm that overcomes these limitations and reconstructs a 4D indoor Manhattan model using construction photographs. Finally, I present a novel user interface that combines image-based rendering and intuitive 4D navigation controls to observe and explore the resulting reconstructio

Abstract (sommario):
In this paper, a new approach to modelling 3D faces based on 2D images is introduced. Here 3D faces are created using two photographs from which we extract facial features based on image manipulation techniques. Through the image manipulation techniques we extract the crucial feature lines of the face in two views. These are then used in modifying a template base mesh which is created in 3D. This base mesh, which has been designed by keeping facial animation in mind, is then subdivided to provide the level of detail required. The methodology, as it stands, is semi-automatic whereby our goal is

Currently, such evidence is captured by taking two-dimensional (2D) color photographs or making a physical cast of the impression in order to capture the three-dimensional (3D) structure of the information. This project aims to build a digitizing device that scans the impression evidence and generates (i) a high resolution three-dimensional (3D) surface image, and (ii) a co-registered two-dimensional (2D) col
