Advanced image segmentation and data clustering concepts applied to digital image sequences featuring the response of biological materials to toxic agents

Roussel, Nicolas (2003-03-27)

Image segmentation is the process by which an image is divided into number of regions. The regions are to be homogeneous with respect to some property. Definition of homogeneity depends mainly on the expected patterns ...
Demosaicking of color images by means of conditional random fields

Kelm, Bernd Michael (2003-10-10)

Modern digital still cameras are equipped with just a single CCD for color image acquisition. Since only one spectral band can be recorded in each pixel, a mosaic of red, green and blue color filters is placed in front o ...
Design of on-line arithmetic networks for signal processing applications : a color filter implementation

Sinky, Mohammed H. (2004-06-10)

Networks of on-line modules for Digital Signal Processing (DSP) applications have been designed and analyzed in many papers. Various arguments have been made for on-line arithmetic over other bit-serial and parallel ap ...
A high-performance, low power and memory-efficient VLD for MPEG applications

Zhang, Haowei (1997-01-14)

An extremely important area that has enabled or will enable many of the digital video services and applications such as VideoCD, DVD, DVC, HDTV, video conferencing, and DSS is digital video compression. The great succe ...
Image features and learning algorithms for biological, generic and social object recognition

Zhang, Wei (2009-03-16)

Automated recognition of object categories in images is a critical step for many real-world computer vision applications. Interest region detectors and region descriptors have been widely employed to tackle the variabili ...
Low-power video decoding with dynamic voltage scaling

Dixit, Reshma (2004-04-08)

This thesis investigates Dynamic Voltage Scaling (DVS) techniques to lower power consumption in video decoding. A DVS scheme called the Frame-data Computation Aware (FDCA) method has been presented. This method is ada ...
Motion-based MPEG video summarization

Colle, Olivier (1999-09-23)

A new, fully automated summarization algorithm of MPEG compressed videos is designed to address the challenge of content based video retrieval. This algorithm segments the MPEG stream motion vector magnitudes using a s ...
Object highlighting : real-time boundary detection using a Bayesian network

Jia, Jin (2004-04-12)

Image segmentation continues to be a fundamental problem in computer vision and image understanding. In this thesis, we present a Bayesian network that we use for object boundary detection in which the MPE (most probab ...
On-line lumber quality control technique using image processing

Aslam, Fatima (1990-06-06)

Product quality control is the back bone for an efficient process control system. By monitoring the size of the board cut in a sawmill, performance of the production system can be controlled. Feedback from the qualit ...
Performance analysis of least square error [omega] filter for image reconstruction from projection

Ahmed, Mahbub I. (1990-11-29)
Power reduction of MPEG video decoding for mobile multimedia systems

Lewis, James M. (2007-12-07)

The purpose of this thesis is to explore methods which can reduce the power dissipation of a mobile system while decoding MPEG video. MPEG decoding is a microprocessor intensive process that makes heavy use of both the ...
