Abstract:

Digital Image-based Elasto-Tomography (DIET) is an emerging technology for non-invasive breast cancer screening. This technology relies on obtaining high resolution images of a breasts surface under high frequency actuation; typically 50-100Hz. Off-the-shelf digital cameras are unable to capture images directly at these speeds and current digital camera set-ups that are potentially capable of high speed image capture are either low in resolution, expensive, or occupy a volume too large to have them placed about the breast in a dense array. A method is presented for obtaining the required high

Abstract:

Animating an articulated figure usually requires expensive hardware in terms of motion capture equipment, processing power and rendering power. This implies a high cost system and thus eliminates the use of personal computers to drive avatars in virtual environments. We propose a system to animate an articulated human upper body in real-time, using minimal motion capture trackers to provide position and orientation for the limbs. The system has to drive an avatar in a virtual environment on a low-end computer. The cost of the motion capture equipment must be relatively low (hence the use of mi

Abstract:

The use of structured light illumination techniques for three-dimensional data acquisition is, in many cases, limited to stationary subjects due to the multiple pattern projections needed for depth analysis. Traditional Composite Pattern (CP) multiplexing utilizes sinusoidal modulation of individual projection patterns to allow numerous patterns to be combined into a single image. However, due to demodulation artifacts, it is often difficult to accurately recover the subject surface contour information. On the other hand, if one were to project an image consisting of many thin, identical strip

Abstract:

Metal fatigue tests are an everyday occurrence that updates existing fatigue libraries, ensuring that structures and components do not fail when in use. The American Society for Testing and Materials (ASTM) provides standard tests whereby certain material properties are obtained by the exact same method for each test, providing designers the information to prevent premature failure. The Fatigue Crack Growth Rate (FCGR) of a standard specimen provides information for situations where a crack may exist in components. The critical size of the crack determines when it is safe to use a component an

Previous modeling of wood materials has included many assumptions of unknown mechanical properties associated with the hierarchical structure of wood.

Abstract:

Interest in elastographic techniques for soft tissue imaging has grown as relevant research continues to indicate a correlation between tissue histology and mechanical stiffness. Digital Image Elasto-Tomography (DIET) presents a novel method for identifying cancerous lesions via a three-dimensional image of elastic properties. Stiffness reconstruction with DIET takes steady-state motion captured with a digital camera array as the input to an elastic property reconstruction algorithm, where finite element methods allow simulation of phantom motion at a range of internal stiffness distributions.

Abstract:

Digital cameras use a single image sensor array with a color filter array (CFA) to measure a color image. Instead of measuring a red, green, and blue value at every pixel, these cameras have a filter built onto each pixel so that only one portion of the visible spectrum is measured. To generate a full-color image, the camera must estimate the missing two values at every pixel. This process is known as color filter array interpolation. The Bayer CFA pattern samples the green image on half of the pixels of the imaging sensor on a quincunx grid. The other half of the pixels measure the red an

Abstract:

In rock constructions and mining it is important to know the current stress situation in the rock due to safety and construction reasons. Two of the widely used stress measurement methods are overcoring and hydraulic fracturing. Both methods are expensive, need new boreholes, and are complex and time consuming. The methods are also limited by the number of successfully achieved measurements series. An alternative method is therefore investigated by locally relieving stresses around the borehole wall using sawn slots. To determine the stresses in the rock, strain measurements will be done using

At present, the FDOT designs OGFC mixtures using a pie plate visual draindown method (FM 5-588).

碩士<br>國立高雄第一科技大學<br>營建工程所<br>98<br>Structural health monitoring techniques are gaining new attention in the field of structural engineering, as they are applicable to on-line structural monitoring, seismic evaluation, and retrofit of old buildings. Structural health diagnosis includes three processes: beginning with the structural state measurement, then identification of the system mode and physical parameters, and finally the structural health condition assessment. In the past, acceleration sensors play an important role to measurement for system identification because of its relatively high

Abstract:

碩士<br>國立雲林科技大學<br>機械工程系碩士班<br>95<br>Digital image correlation (DIC) method is a whole-field, non-contact, and non-destructive strain measuring method. This method compares the digital images of the surface of a specimen taken before and after deformation to find the displacement and strain of a selected subset. This study applies adaptive real-parameter genetic algorithm (ARGA) to seek for the optimum solutions. To improve the digital image correlation method, the previous program has been modified to reduce its error, and the effects of population size, generation number, and iteration number

碩士<br>國立中興大學<br>機械工程學系所<br>94<br>This research is based on digital image processing technology where the in-plane deformation/displacement can be computed based on image correlation method with the sequential surface images of the object and could be acquired by a CCD camera. The advantage of implementing digital image correlation method on displacement/deformation measurement includes a measuring scale without limit as well as its utility for extremely large scale image acquisition purposes obtained by synthetic aperture radar for analysis of earth''s crust plate displacement and for SEM ima

碩士<br>國立高雄大學<br>土木與環境工程學系碩士班<br>99<br>The satellite image has following characteristics: short capture period, ability to detect the change of the earth surface rapidly, large coverage, large amount of information, multiple spectra and the ability of repeating observations. Therefore, instead of the traditional method of site investigation, which is limited by weather conditions, expenditure, and traffic situation, the remote sensing technology based on satellite image is gradually used to determine the occurrence locations of landslide disasters and their quantities. In this study, we appl

碩士<br>國立臺灣大學<br>電信工程學研究所<br>88<br>Digital still cameras have been widely used as image input device nowadays. Before a color image is generated, a lot of color image processes must be performed. Among these color image processes, the Color Filter Array (CFA) interpolation maybe the most important image process in digital still cameras. In this dissertation, we study the CFA interpolation problem, and we also develop an effective CFA interpolation algorithm. Recently, the idea of trustworthy digital camera is proposed. Digital cameras with automatic watermark function will be a new trend i

Digital image correlation (DIC) has been surged as a full-field speckle measurement technique for in-plane and out-of-plane dynamic mechanical structure analyses. However, up to date, one of the key issues in DIC is still remained in boundary edge detection since a surface edge is not detectable between two discrete neighboring height jumps due to undesi

The digital image correlation method’s advantages have: simple structure, smaller environmental factors effect than other measurement method. It can use as local measurement or global measurement of non-contact. As research priorities in this thesis, via reduce the digital image correlation method of computation is a key to improved computing
