We humans are exquisitely good at seeing patterns, discovering visual relationships, and understanding visual information. Through the network of projections from the visual cortex, visual perception informs and influences the hypotheses we generate, the semantics we assign to visual structures, and the way we interpret the world around us.
We are on the crest of a new wave in Electronic Imaging. The rapid increases in computer processing, storage and bandwidth have made it possible to capture, distribute and process vast quantities of data. This has led to the demand for more intuitive tools for searching, retrieving, and browsing large image libraries, and for finding patterns and relationships in large, multi-type data archives. Solving these problems involves building electronic imaging systems that are matched to the visual and cognitive capabilities of their human users.
In this lecture, I will explore this challenge, and demonstrate some of our work in this area. I will describe some of our recent work in color, image, and shape perception, and show how the results of these experiments have been integrated into tools for helping people analyze, manipulate and understand their data. I will also illustrate this talk with prototype applications we have built that use these tools in a variety of domains, including life sciences, finance, and digital libraries.
Bernice E. Rogowitz is an Experimental Psychologist specializing in human vision and its applications in imaging systems. She earned her Ph.D. at Columbia University, and was an NIH postdoctoral fellow in the Laboratory of Psychophysics at Harvard University.
She currently manages the Visual Analysis Group at the IBM T.J. Watson Research Center in New York. The goal of this group is to develop perceptually-based, intelligent, interactive systems for manipulating, synthesizing and understanding data. This involves experimental research in human perception, the development of interactive software tools for representing and exploring data, and projects with customers to develop these methods within the context of real-world problems.
Some recent projects include WEAVE-- a method for visually linking representations of statistical, geometric and image data, ISEE-- a method for organizing and searching an archive of images by semantic meaning, based on the results of perceptual image similarity experiments, and the WHICH BLAIR PROJECT-- a perceptual method that guides the selection of colormaps for internet data visualization.
In 1988, Dr. Rogowitz founded the IS&T/SPIE Conference on Human Vision and Electronic Imaging, which she continues to co-chair. In 1990, she was general co-chair for the IE&T/SPIE Conference on Electronic Imaging. She has served on the board of the International Imaging Society (IS&T) since 1997. In 2000, Dr. Rogowitz was elected a Fellow of the International Imaging Society (IS&T), in 2001, was appointed an Associate Editor for the IS&T/SPIE Journal of Electronic Imaging, and is the 2002 IS&T Visiting Lecturer.
