Model-Based Speech Enhancement
… 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 estimate accurately the acoustic features (voicing, fundamental frequency, spectral envelope …

Model based capability assessment
As processing, modeling software and design experience become more advanced, the idea of designing a system through models has gained traction in numerous Department of Defense programs. The efficiency gains piloted through implementation of models in the engineering process have also prompted the …

MODEL-BASED 3-D VISION
… a specific method of identifying 3-D objects based on a single view. A new approach of recognizing 3-D objects based on fuzzy subset theory is proposed in this thesis. This method uses Zernike moment invariants of the silhouette of the unknown object to form a set of fuzzy-weighted quantities …

Model-Based Measures of Interrater Agreement
… (2008) propose a generalized linear mixed model for the agreement process, showing that Cohen's κ can seriously underestimate agreement and proposing a model-based coefficient κ<sub>M</sub> which does not suffer from this flaw (at least when the assumed model is correct). They …

Model-Based Measures Of Interrater Agreement
… and tested in rodent and non-human primate models, which revealed that JWS not only improved some cognition-related task functions in animal models but also might be useful in neuropsychiatric conditions. Molecular modeling studies were further utilized to demonstrate that JWS bonded to AChE …

Model-based identification of Oriental documents
… document images. This thesis is concerned with a model-based classification of Oriental documents into Chinese, Japanese, and Korean. A model-based approach locates an object, of which the computer has a model in an image. In this work, the objects to be located are some of the most frequently …

Model-Based Tracking of Articulated Objects
Unique aspects of this work include on-line model-based generation of complex features for use as templates, the characterization of uncertainties in point feature motion for use in assimilating feature tracking results, the use of the sum-of-squared-differences (SSD) image correlation measure as a …

A tool for model-based engineering
… To provide system level performance analysis, Model-Based Engineering (MBE) or virtual integration is becoming more popular in the avionics industry as well as other manufacturers of Cyber-Physical Systems (CPS), which also include the automotive and medical industries. Virtual integration …

CAD Model-Based 3D Scene Reconstruction
… method involves retrieving the best-matching CAD model for each observed object from a database and aligning it with the corresponding input. This technique yields a CAD model-based 3D scene representation that is compact, contains realistic shapes, and is well-suited for a wide range of …

Model-based Experimental Design in Electrochemistry
… homogeneous catalytic reactions. The approach is model-based and the classical Butler-Volmer description is chosen to describe the fundamental electrochemical reaction at a conductive interface. The methodology focuses on two significant design variables: the applied potential at the electrode and …

Model-based active learning in hierarchical policies
… environment is a large topological map roughly based on downtown Vancouver, British Columbia. Higher level abstract tasks are also learned in this process using a model-based extension of the MAXQ algorithm. Our solution demonstrates how HRL can be scaled to large applications with complex, …

Hidden Markov model based visual speech recognition
… speech processing are presented. Classifiers based on Hidden Markov Model (HMM) are first explored for modeling and identifying the basic visual speech elements. Considering that the temporal features of visual speech elements may be confusable and sensitive to their contexts, three novel …

Identifying Untraited Individuals Using Model-Based Measurement
… research into the development and fine-tuning of models of untraited item responding. Implications of untraitedness are also discussed in the context of personality testing in organizational settings.
