Applications of Image Processing
Professor Gabor T. Herman
Discrete Imaging and Graphics Group
Doctoral Program in Computer Science, The Graduate Center of CUNY

This presentation reports on ongoing doctoral research on applications of image processing in electron micrsoscopy, hearing aid design,  and materials science.

High Dimensional Space Clustering
Professor Robert Haralick
Pattern Recognition Laboratory
Doctoral Program in Computer Science, The Graduate Center of CUNY
Digital Image Registration
Professor George Wolberg
Computer Science Department, City College of New York /CUNY

Log-polar transforms and nonlinear least squares optimization algorithms converge to yield robust alignment results. The images to be registered may differ by large-scale changes in rotation, scale, translation, and mild perspective distortions. Applications in recognition, mosaicing, and video stabilization will be shown.
Smart Projectors
Professor Michael Grossberg
Computer Science Department, City College of New York /CUNY

Projectors make it possible to create displays and interfaces on everyday surfaces. They can also be viewed as precisely controllable illumination sources for algorithms which use structured light. Nevertheless the resulting appearance of a projected image depends on the
reflectance of the surface. We will describe methods we developed to compensate for the changing reflectance of a surface toward creating a desired appearance independent of the surface.
Multimodal Sensing Integration for Surveillance and Inspection
Professor Zhigang Zhu
Computer Science Department, City College of New York /CUNY

A multimodal integration approach will be presented for human detection and building inspection. The sensor modalities include a Laser Doppler vibrometer (for voice or vibration detection), a Thermal IR camera (with accurate temperature measurement) and a PTZ color camera (for human tracking or façade documentation). 
Photorealistic 3D Modeling of Large-Scale Scenes: Integration of 3D Range and 2D Intensity Sensing in a Complete System
Professor  Ioannis Stamos
Department of Computer Science, Hunter College, CUNY

We are building a system that can automatically acquire 3D range scans and 2D images to build geometrically and photometrically correct 3D models of urban environments. A major bottleneck in the process of 3D scene acquisition is the automated registration of a large number of geometrically complex 3D range  scans and high-resolution 2D images in a common frame of reference. We have developed novel methods for the accurate and efficient registration of a large number of 3D range scans. The methods utilize range segmentation and feature extraction algorithms. We have also developed a context-sensitive user interface to overcome problems emerging from scene symmetry. Finally, we developed efficient algorithms for the 3D range to 2D image registration problem in urban scene settings. These algorithms calibrate each 2D camera and compute an optimized transformation between the 2D images and 3D range scans. A mesh-simplification method of the final 3D model based on the segmentation results of each range image has been produced as well. The generated 3D representations are useful for urban planning, historical preservation, or entertainment applications.
Geographic Information Systems, Remote Sensing, and Photogrammetry
Professor  Sean Ahearn
Department of Geography, Hunter College, CUNY

Tangible User Interfaces
Professor Lori L. Scarlatos
Department of Computer and Information Science, Brooklyn College, CUNY

Tangible user interfaces provide a seamless interface between humans, digital information, and the physical environment. This creates a more transparent interface, allowing the user to focus on the task at hand. Several applications of tangible user interfaces and other physical computing interfaces will be presented.
New Method of Optimization in the Theory of Schedules
Professor Yakov Genis
Computer Science Department, Borough of Manhattan Community College /CUNY

The presentation shows a new method of optimization of job performance schedule. By following this method we can minimize the maximum of sum of job rates and make it more uniform-like. A VB code will visualize this process. Application areas are: the scheduling for repair works, the scheduling for media program delivery that satisfies the maximum number of subscribers etc.
