Medical image enhancement
Each image acquired from a medical imaging system is often part of a two-dimensional (2-D) image set whose total presents a three-dimensional (3-D) object for diagnosis. Unfortunately, sometimes these images are of poor quality. These distortions cause an inadequate object-of-interest presentation, …

Model-Based Speech Enhancement
Abstract A method of speech enhancement is developed that reconstructs clean speech from a set of acoustic features using a harmonic plus noise model of speech. This is a significant departure from traditional filtering-based methods of speech enhancement. A major challenge with this approach is to …

Axial compressor stability enhancement
Aircraft jet engines must operate in a stable manner at all times. One source of instability is compressor stall. Stall problems can be reduced by machining cavities into the compressor casing adjacent to the rotor blades. This ‘casing treatment’ is the focus of the present work. Two treatment …

Bayesian algorithms for speech enhancement
… transmitted through such devices, but speech enhancement algorithms can ameliorate this degradation to some extent. The development of speech enhancement algorithms that improve the quality of noisy speech is the aim of this thesis, which consists of three main parts.<br/>In the first part, we …

Tongue based hearing enhancement system
The number of hearing impaired people have been getting increased all over the world. Cochlear implantation is considered as a primary treatment of high degree hearing impairment. However, there still exist some risks and side effects of this surgical procedure even though there have been a lot of …

Fingermark Enhancement on Metallic Surfaces
… has allowed their use in latent fingermark enhancement to be investigated for the first time. This study has shown that it is possible to prepare gold nanoparticles by laser ablation and incorporate them in a technique that uses colloidal gold solutions (SMD-II) and show potential as a novel …

PLED Enhancement and Re-use
Polymer light emitting diodes (PLEDs) represent new technology for display applications. However, these polymer based devices could benefit from increased efficiency and material longevity. This thesis examines how preprocessing PLED indium tin oxide (ITO) anodes and reprocessing previously used …

High intensity femtosecond enhancement cavities
To produce extreme ultraviolet radiation via high harmonic generation (HHG) in rare gases, light intensities in excess of 1014 W/cm 2 are required. Usually such high intensity are obtained by parametric amplification of laser pulses, which in turn reduces the pulse repetition rate to a few kHz. …

Enhancement and stylization of photographs
… enhancing and stylizing their photographs. These enhancements range from basic exposure and contrast adjustments to dramatic alterations. It is these enhancements - along with composition and timing - that distinguish the work of professionals and casual photographers. The goal of this thesis is …

Enhancement Techniques of Boiling Heat Transfer
… of EH-14 and SA-9 compared to water. The maximum enhancement obtained is 66.27% for 300ppm aqueous SLS solution. However, the maximum enhancement in heat transfer coefficient is 24.31% for 1600ppm EH-14 and 22.09% for 200ppm SA-9. Boiling visualization shows that boiling with surfactant solutions …

Speech enhancement using multisensory cooperative computing
… novel approaches for audio-visual speech enhancement (AVSE) through biologically inspired architectures, lightweight multimodal learning, and hybrid classical–deep frameworks. It advances three complementary themes of the speech enhancement problem. First, Multisensory Cooperative …

ENHANCEMENT AND RESTORATION OF DUST IMAGES
… of dust noise on ordinary images and formulating enhancement and restoration strategies to improve the quality of dusty images using a sequence of image processing steps. Analyses of images acquired in dusty environments show that the images tend to have noise, blur, a small dynamic range, low …

Speech enhancement for real-time applications
Segmental exemplar-based speech enhancement algorithms are promising for real-world applications as they can function well without noise training, meaning they can easily generalize to real-world applications. They are, however, typically slow due to needing to search through a corpus that is …
