A domain independent adaptive imaging system for visual inspection
… the relevant information. This part of the imaging system inherently introduces many errors. The aim of this project is to reduce the error rate produced by such algorithms and make them adaptable to change in the manufacturing process. Thus a prior knowledge is needed about the image and …

A stereo vision system with automatic brightness adaptation
… the development of an automatic brightness adaptive imaging system for use in stereo vision algorithms implemented for a variety of processing architectures. A 256 x 256 array of wide dynamic range pixels with on-chip A/D converters provides the digital data path for a feedback network which …

Backscatter Spatial Coherence for Ultrasonic Image Quality Characterization: Theory and Applications
<p>Adaptive ultrasound systems, designed to automatically and dynamically tune imaging parameters based on image quality feedback, represent a promising solution for reducing the user-dependence of ultrasound. The efficacy of such systems, however, depends on the ability to accurately and reliably …

Non-contact quantitative imaging of limbs, bone and tissue, using ultrasound tomographic techniques
… sets collected on two custom built ultrasound imaging systems for limb imaging. The images are quantitative in that the distribution of sound speeds and dimensionally accurate geometry of tissue structures are reconstructed. The first imaging system is based on laser generation and detection of …

Statistical modeling of radiation detection and imaging system
In the development of SPECT system for imaging small animal in vivo, higher spatial resolution is continuously sought to provide improved spatial detail and image quality. However, the pursuit of high resolution often results in the poor photon collection efficiency and limited quantitative …

Characterisation and monitoring of mineral deposits in down-hole petroleum pipelines.
… systems. With respect to monitoring deposits, an adaptive imaging re-construction algorithm was developed to simulate imaging, which maps the cross-sectional profile of the pipeline, in pseudo-real time. A main feature of the software is that it estimates the arbitrary position of the probe array …
