Efficient watershed algorithms for image segmentation and related prototype architectures

Rambabu, C (2004)

Image segmentation is concerned with decomposing a given image into its constituent regions or objects. It is an important preliminary step in diverse fields of application like object recognition, image compression, medical ...
New developments in median filters

Singh, Khumanthem Manglem (2006)

The median filter is a nonlinear filter that outputs the median of the data inside a moving window of predetermined length and has been traditionally used to remove impulse noise from images. The filter is known for its ...
Vision based dynamic hand gesture recognition for human computer interaction

Bhuyan, Manas Kamal (2006)

With the increased interest in human-computer interaction (HCI), there has been rapid growth of research related to gesture recognition in recent years. Hand gesture recognition from visual images forms an important part ...
Feature analysis and compensation for speaker recognition under stressed condition

Raja, G. Senthil (2007)

This thesis documents our investigations on feature analysis and design of compensators for speaker recognition under stressed condition. Any condition that causes a speaker to vary his or her speech production from normal ...
Motion- coherent video watermarking

Vinod, P. (2007)

One of the challenging security issues in video watermarking is the inter-frame collusion attacks. These attacks exploit the inherent redundancy in the video frames or in the watermarks to produce an unwatermarked copy of ...
Limit cycle approach for identification and control of processes

Padhy, Prabin Kumar (2007)

The thesis is concerned with identification and control of single-input-single-output (SISO) and two-input-two-out (TITI) processes based on relay induced limit cycles. A relay based on-line identification method for stable ...
Controller Design Methods for Linear systems with Emphasis on Integrating Processes

Ali, Ahmad (2008)

Certain new approaches for designing efficient controllers for linear systems, in particular, for integrating processes, are proposed in this thesis. The parameters of the proposed proportional integral- derivative (PID) ...
Modelling of multi-antenna wireless channels and relay based communication systems

Paul, Babu Sena (2009)

Different issues related to modelling of multi-antenna wireless channels and relay based communication systems have been investigated in this thesis. The effects of array geometry and orientation of arrays in aMIMO system ...
Adaptive Network based Fuzzy Inference System (ANFIS) as a Tool for System Identification with Special Emphasis on Training Data Minimization

Buragohain, Mrinal (2009)

Nearly two decades back nonlinear system identification consisted of several ad-hoc approaches which were restricted to a very limited class of systems. However, with the advent of the various soft computing methodologies ...
Cardiovascular Signal Compression Using a New Wavelet Energy Based Diagnostic Distortion Measure

Manikandan, M. Sabarimalai (2009)

This thesis presents an adaptive wavelet based compression method for cardiovascular signals. Generally, the performance of the lossy compression system depends on the methodologies used for compression and the quality ...
Limited Data Speaker Recognition

Jayanna, H S (2009)

This work demonstrates the task of recognizing the speaker with the constraint of limited data. The performance of the speaker recognition system depends on the techniques employed in the analysis, feature extraction, ...
Optimization of Planar Spiral Inductor and Design of Multilayer Pyramidal Inductor for Silicon Radio Frequency Integrated Circuits

Haobijam, Genemala (2009)

Silicon integrated passive devices have been gaining importance with the need to integrate more functionalities on a single chip to realize the complex systems on chip. .....
Combined Temporal and Spectral processing methods for speech Enhancement

Krishnamoorthy, P. (2009)

This thesis proposes a combined temporal and spectral processing(TSP) approach for the enhancement fo degraded speech. There major sources of degradation, namely, background noise, reverberation and speech from the competing ...
Perceptual Hashing for Wavelet-Based Scalably-Coded Video

Saikia, Navajit (2010)

A perceptual hash function for video extracts a Dxed-length binary string called the perceptual hash on the basis of the perceptual content of the video. Besides being sensitive to the content diDerences in videos, a ...
Design of Robust Fuzzy Controllers for Uncertain Nonlinear Systems

Senthil, Kumar D (2010)

This thesis deals with the analysis and design of robust fuzzy controllers for uncertain nonlinear systems using Takagi-Sugeno (T-S) model based approach. A T-S fuzzy model is used here to approximate the uncertain nonlinear ...
Design of amplifiers and fabrication of high performance thin-film transistors using carbon nanotubes

Narasimhamurthy, K. C. (2011)

The work carried out in this thesis is divided into three parts. The first part discusses the study on carbon nanotubes (CNT) interconnects. The second part will be dealing with the modelling of CNT based transistors and ...
Addressing pitch Mismatch for Children's Automatic Speech Recognition

Ghai, Shweta (2011)

This thesis addresses the acoustic mismatch due to pitch differences between the adults' and the children's speech for children's automatic speech recognition (ASR) on adult's speech trained models. The motivation for the ...
PERFORMANCE ENHANCEMENT OF MICROWAVE DEVICES USING METAMATERIAL BASED SUB-WAVELENGTH RESONATORS

Karthikeyan, S. S. (2011)

Metamaterials are new artificial materials with unusual electromagnetic properties, not commonly found in nature. All natural materials have positive magnetic permeability and electric permittivity. In contrast, in ...
Relay Feedback Method for Process Modelling

Mehta, Utkal V. (2011)

From a practical and simplicity point of views, the relay feedback identification is extended to the various fields of process control industries. The proposed techniques yield significantly improved accuracy over the ...
Cooperative Relaying with Multi-Antenna System in Fading Channel

Katiyar, Himanshu (2011)

In this thesis, performance of cooperative relaying with multi-antenna system in Rayleigh/Nakagami-m fading channels has been investigated. The relay is assumed to operate in adaptive decode and forward mode and perform ...
