Ultralow-Voltage High-Speed Flash ADC Design Strategy Based on FoM-Delay Product Abstract? The ultralow-voltage (ULV) design strategy for high-speed flash analog-to-digital converters (ADCs). A lower supply voltage decreases the energy consumption at the cost of conversion speed. A new index, the figure-of-merit (FoM)-delay (FD) product, is introduced to provide a balance between the energy efficiency and…
Unified VLSI architecture for photo core transform used in JPEG XR Abstract? In JPEG XR image compression technique the unified photo core transform is used. It is designed to support high dynamic range and high definition formats thus this type of JPEG XR image compression with unified photo core transform is widely used in real…
UNION: A Unified Inter/Intrachip Optical Network for Chip Multiprocessors Abstract?As modern computing systems become increasingly complex, communication efficiency among and inside chips has become as important as the computation speeds of individual processing cores. Traditionally, to maximize design flexibility, interchip and intrachip communication architectures are separately designed under different constraints. Jointly designing communication architectures for…
Universal Network Coding-Based Opportunistic Routing for Unicast Abstract?Universal Network Coding-Based Opportunistic Routing for Unicast. Network coding-based opportunistic routing has emerged as an elegant way to optimize the capacity of lossy wireless multihop networks by reducing the amount of required feedback messages. Most of the works on network coding-based opportunistic routing in the literature assume that…
Unprivileged Black-Box Detection of User-Space Keyloggers Abstract?Software keyloggers are a fast growing class of invasive software often used to harvest confidential information. One of the main reasons for this rapid growth is the possibility for unprivileged programs running in user space to eavesdrop and record all the keystrokes typed by the users of a system.<...
Unraveling the Effect of Textured Contact Lenses on Iris Recognition Abstract?Unraveling the Effect of Textured Contact Lenses on Iris Recognition. The presence of a contact lens, particularly a textured cosmetic lens, poses a challenge to iris recognition as it obfuscates the natural iris patterns. The main contribution of this paper is to present an in-depth…
Unsupervised Colour Image Segmentation using Dual-tree Complex Wavelet Transform Abstract?a novel image segmentation technique for noisy colour images, in which the heavy-tailed characteristics of the image are modelled by Cauchy distributions. First, the RGB colour bands of the noisy image are decomposed into multiresolution representations using the dual-tree complex wavelet transform.< Final Year Project >…
Unsupervised Deep Learning Applied to Breast Density Segmentation and Mammo graphic Risk Scoring Abstract?Mammo graphic risk scoring has commonly been automated by extracting a set of handcrafted features from mammograms, and relating the responses directly or indirectly to breast cancer risk. We present a method that learns a feature hierarchy from unlabeled data. < final...
Unsupervised Feature Selection with Controlled Redundancy (UFeSCoR) Abstract? Unsupervised Feature Selection with Controlled Redundancy (UFeSCoR). Features selected by a supervised / unsupervised technique often include redundant or correlated features. While use of correlated features may result in an increase in the design and decision making cost, removing redundancy completely can make the system vulnerable to…
Unsupervised Multi-Spectral Satellite Image Segmentation Combining Modi fied Mean-Shift and a New Minimum Spanning Tree Based Clustering Technique Abstract?Unsupervised Multi-Spectral Satellite Image Segmentation Combining Modi fied Mean-Shift and a New Minimum Spanning Tree Based Clustering Technique. An unsupervised object based segmentation, < Final Year Projects > combining a modified mean-shift (MS) and a novel minimum…
Unsupervised SAR Image Change Detection Based on SIFT Key points and Region Information Abstract?This letter presents a new unsupervised distribution-free change detection method for synthetic aperture radar (SAR) images based on scale-invariant feature transform (SIFT) keypoints and region information. Since the SIFT can detect blob-like structures in an image and be insensitive to noise, we…
Unsupervised segmentation? classification? cervical cell image Abstract?Unsupervised segmentation and classification of cervical cell image. The Pap smear test is a manual screening procedure that is used to detect precancerous changes in cervical cells based on color and shape properties of their nuclei and cytoplasms. Automating < Final Year Projects > this procedure is still an…
