Adaptive Multiresolution Image And Video Compression And Pre/Post-Processing Of Image And Video Streams , Hamid R. Rabiee, R. L. Kashyap Nov 1996

Adaptive Multiresolution Image And Video Compression And Pre/Post-Processing Of Image And Video Streams , Hamid R. Rabiee, R. L. Kashyap

Department of Electrical and Computer Engineering Technical Reports

This report is divided into two sections. In the first section, the focus is on adaptive transform-based image compression and motion compensation at low bit rates. A new adalptive algorithm for image representation and coding is introduced. This algorithm is based on the concept of segmented orthogonal matching pursuits (SOMP), and adaptively selects the best representation from an overcomplete dictionary of wavelet functions. In the second section, the pre-processing and post-processing of images and video streams are focused on. A new robust nonlinear filter based on the theory of generalized maximum likelihood and order statistics (GMLOS) is introduced. It is …

Reconciling Bilateral Trade Data For Use In Gtap, Mark Gehlhar Oct 1996

Reconciling Bilateral Trade Data For Use In Gtap, Mark Gehlhar

GTAP Technical Papers Archive

Bilateral trade flows are reported by both importers and exporters. Large discrepancies in reported import/export trade flows can be found when these two reports are compared.

The GTAP database requires consistency between the export flow and its corresponding import flow for all partner pairs. Therefore, bilateral trade data in its reported form cannot be directly used for GTAP. Various methods can be used to produce a consistent set of bilateral trade flows. However, achieving consistency alone does not necessarily provide credible trade flows.

Matrix balancing using trade totals published by international agencies is not appropriate since these totals are not …

Image Compression And Signal Classification By Neural Networks And Projection Pursuits, M. Fardanesh, O. K. Ersoy Sep 1996

Image Compression And Signal Classification By Neural Networks And Projection Pursuits, M. Fardanesh, O. K. Ersoy

Department of Electrical and Computer Engineering Technical Reports

In this report, two applications of neural networks are investigated. The first one is low bit rate image compression by using neural networks and projection pursuit. The second one is improving the classification accuracy of neural network classifiers by using unlabeled data. In the first part, a novel approach for low bit rate image coding is presented. The image is compressed by first quadtree segmenting the image into blocks of different sizes based on two activity measures , and then constructing a distinct code for each block by invokin~gth e theory of projection pursuit. The two activity measures used in …

Effect Of Value Based Software Engineering On Development Projects, Raymond Paul, Mageda A. Sharafeddin, Y. Shinagawa, Arif Ghafoor Jul 1996

Effect Of Value Based Software Engineering On Development Projects, Raymond Paul, Mageda A. Sharafeddin, Y. Shinagawa, Arif Ghafoor

Department of Electrical and Computer Engineering Technical Reports

Previous models of software development projects have failed to represent people productivity accurately. In this paper, we present a model characterized by realistic productivity curves and flexibility in choosing resource factors in a software engineering project. A two-mode mathematical model similar to PutnamNorden model js presented. The proposed model enhances the capability of engineering management users to make corrective actions when appropriate. It is extremely beneficial to detect problems and provide corrective actions since they are in many cases crucial to the successful project software engineering hiring and/or acquisition management planning to use the software product.
