-Finding a new application for an old concept is a tried and true method for developing research projects that lead to theses and dissertations. This talk describes how a solution to a business problem morphed into a dissertation research project. Forecasting closure and default rates for CAPITAL’s client bank portfolios is a key component of our business. The historical models and algorithms used to predict these rates were unable to capture changes in the portfolio due to the limitations of their base assumptions. To solve this problem, a data driven approach using macroeconomic conditions and account level information within a survival model framework improved estimates which resulted in improved profitability for CAPITAL’s clients.+The number of photographs available on-line is increasing by perhaps hundreds of millions each week. Understanding the content of these photos is often easy for human beings, yet challenging for computers. This colloquium will describe some current approaches to producing 3D models from sets of photographs. The typical stages of this computation include choosing a coordinate system, locating the cameras within this coordinate system, finding patterns of pixels that are shared in two or more photographs, and putting these patterns together into a single geometric structure. If there is time, we will also consider extensions to 3D video.

Upcoming Colloquium

Olaf Hall-Holt, Thursday, November 17, 2:30 in RNS 310

3D Models From Photos

The number of photographs available on-line is increasing by perhaps hundreds of millions each week. Understanding the content of these photos is often easy for human beings, yet challenging for computers. This colloquium will describe some current approaches to producing 3D models from sets of photographs. The typical stages of this computation include choosing a coordinate system, locating the cameras within this coordinate system, finding patterns of pixels that are shared in two or more photographs, and putting these patterns together into a single geometric structure. If there is time, we will also consider extensions to 3D video.
