Automatic Indexing of Newspaper Microfilm Images

This paper describes a proposed document analysis system that aims at automatic indexing of digitized images of old newspaper microfilms. This is done by extracting news headlines from microfilm images. The headlines are then converted to machine readable text by OCR to serve as indices to the respective news articles. A major challenge to us is the poor image quality of the microfilm as most i...

Magnetic Orders in the Double Exchange Model in Infinite Dimensions

We studied magnetic properties of the double exchange (DE) model with S = 1/2 localized spins at T = 0, using exact diagonalization in the framework of the dynamical mean field theory. Obtained phase diagram contains ferromagnetic, antiferromagnetic and paramagnetic phases. Comparing the phase diagram with that of the DE model with classical localized spins, we found that the quantum fluctuatio...

Newspaper Headlines Extraction from Microfilm Images

Automatic indexing is important for a digital library to provide digitized manuscripts of old document images and their electronic text. As an essential step in creating such a system, this paper discusses the issue of extracting headlines from old newspaper microfilms. Most research on document layout analysis has largely assumed relatively clean images. However microfilm images of old newspap...

A Tale of Two Trading Venues: Electronically Delivered Orders vs. Floor Brokered Orders on the American Stock Exchange

At the American Stock Exchange (Amex), electronically-routed orders (referred to as "system orders") from "upstairs" traders interact on the Amex trading floor with each other and with orders "worked" by brokers. In addition, we see that brokers receive orders from clients and other traders who have chosen to involve a floor broker as an intermediary in the trading process. The quality of the t...
