Soft Scissors : An Interactive Tool for Realtime High Quality Matting
Soft Scissors High Quality Matting
2016/5/24
We present Soft Scissors, an interactive tool for extracting alpha mattes
of foreground objects in realtime. We recently proposed a novel
offline matting algorithm capable of extracting high-quality...
Ensuring High-Quality Randomness in Cryptographic Key Generation
Cryptographic Key Generation High-Quality Randomness
2015/8/5
The security of any cryptosystem relies on the secrecy of the system's secret keys. Yet, recent experimental work demonstrates that tens of thousands of devices on the Internet use RSA and DSA secrets...
Improving Recommendation Quality by Merging Collaborative Filtering and Social Relationships
Collaborative Filtering Recommender Systems Social Networks Matrix Factorization
2015/7/21
Matrix Factorization techniques have been successfully applied to raise the quality of suggestions generated by Collaborative Filtering Systems (CFSs). Traditional CFSs based on Matrix Factorization o...
Practical Signal Quality Monitoring for Augmentation Systems
Practical Signal Quality Monitoring Augmentation Systems
2015/6/26
Signal Quality Monitoring (SQM) algorithms propose to detect anomalous GPS signal distortions primarily through the use of multicorrelator SQM receivers. However, currently no augmentation systems (e....
Bounds on Service Quality for Networks Subject to Augmentation and Attack
Network Vulnerability Attack
2014/12/18
Assessing a network's vulnerability to attack and random failure is a difficult and important problem that changes with network application and representation. We furnish algorithms that bound the rob...
Scheduling Heuristics for Maximizing the Output Quality of IRIS Task Graphs in Multiprocessor Environment with Time and Energy Bounds
precedence constraints computational load cost functions reward service dynamic voltage scaling
2014/12/8
Embedded real time applications are often subject to time and energy constraints. Real time applications are usually characterized by logically separable set of tasks with precedence constraints. The ...
A Transcription Task for Crowdsourcing with Automatic Quality Control
Transcription crowdsourcing quality control
2014/11/27
In this paper, we propose a two-stage transcription task design for crowdsourcing with an automatic quality control mechanism embedded in each stage. For the first stage, a support vector machine (SVM...
Data Quality Assessment and rainfall Estimation Using Dense Radar Networks
Applied sciences Data quality Estimation Dense radar networks Quality assessment Radar Rainfall
2014/11/7
While their coverage is adequate for many applications, due to the Earth's curvature and terrain induced blockage, today's operational long-range weather surveillance radar networks lack the capabilit...
An Investigation on the Effectiveness of Features for Translation Quality Estimation
Investigation Effectiveness Features Translation Quality Estimation
2014/3/20
We describe a systematic analysis on the effectiveness of features commonly exploited for the problem of predicting machine translation quality. Using a feature selection technique based on Gaussian P...
Modelling Annotator Bias with Multi-task Gaussian Processes: An Application to Machine Translation Quality Estimation
Modelling Annotator Bias Multi-task Gaussian Processes:Machine Translation Quality Estimation
2014/3/20
Annotating linguistic data is often a complex, time consuming and expensive endeavour. Even with strict annotation guidelines, human subjects often deviate in their analyses, each bringing different b...
Reducing Annotation Effort for Quality Estimation via Active Learning
Reducing Annotation Effort Quality Estimation via Active Learning
2014/3/20
Quality estimation models provide feedback on the quality of machine translated texts. They are usually trained on humanannotated datasets, which are very costly due to its task-specific nature. We in...
