Image Retrieval using Landmark Indexing for Indoor Navigation
(2014-04-25)A novel approach is proposed for real-time retrieval of images from a large database of overlapping images of an indoor environment. The procedure extracts visual features from images using selected computer vision techniques, ... -
Impact Study of Multimode Fibre Taper in Modal Noise Under Restricted Offset Launch Conditions
(2007-11-15)Delivering high bandwidth to the individual household or small business is currently a major bottleneck in the high speed network, a problem referred to as the last mile issue. Multimode fibre is widely deployed in the ... -
Imperceptible Pattern Embedding: Structured Light Steganography For Augmented Reality Applications
In this work, we describe a novel PROCAM sensor which uses steganographic techniques to embed imperceptible patterns in structured light, allowing a projector to function both as a versatile display device and a sensor for ... -
Imperceptible Structured Light Projection Mapping for Augmented Reality
A novel method is proposed to imperceptibly embed structured light patterns in projected content and decode them to extract a real time range image stream suitable for dynamic projection mapping applications. A commercially ... -
Implementation of coarse-grain coherence tracking support in ring-based multiprocessors
(2007-10-25)As the number of processors in multiprocessor system-on-chip devices continues to increase, the complexity required for full cache coherence support is often unwarranted for application-specific designs. Bus-based interconnects ... -
Implications of Fiber Nonlinearities on Coherent Optical Fiber Communications
A primary objective of optical system design is to satisfy the ever-increasing capacity demand for communication services. Fulfilling this target by increasing the cardinality of modulation formats is at the expense of a ... -
Improved Land Vehicle Navigation and GPS Integer Ambiguity Resolution Using Enhanced Reduced-IMU/GPS Integration
(2014-06-24)Land vehicle navigation is primarily dependent upon the Global Positioning System (GPS) which provides accurate navigation in open sky. However, in urban and rural canyons GPS accuracy degrades considerably. To help GPS ... -
Improved Resonant Converters for Wide Voltage Range, High Current DC-DC and Universal AC-DC Applications
Data centers are the cornerstone of business in modern society and individual lives. Of similar significance to daily life is the external AC-DC power supply exemplified by the cell phone charger. In both applications, ... -
Improvement of Speckle-Tracked Freehand 3-D Ultrasound Through the Use of Sensor Fusion
(2009-10-20)Freehand 3-D ultrasound (US) using a 2-D US probe has the advantage over conventional 3-D probes of being able to collect arbitrary 3-D volumes at a lower cost. Traditionally, generating a volume requires external tracking ... -
Improving Code Search Using Learning-to-Rank and Query Reformulation Techniques
(2015-07-24)During the process of software development, developers often encounter unfamiliar programming tasks. Online Q&A forums, such as StackOverflow, are one of the resources that developers can ask for answers to their programming ... -
