Research

The current focus is on processing of bi-level images such as text pages and bar codes. Theoretically, the pixels of such images can have only two possible values. The practical situation is quite different. The optical system of the scanner causes blurring, illumination may be uneven, and so forth. As a result the scanned images contain a range of values. Simple techniques, such as thresholding, have serious limitations. The laboratory has pioneered techniques that allow the recovery of the ideal image even when blurring and other distortions are severe. Click here for a List of Publications

Recently we have resumed work in the area of interactive graphics and particularly in problems where image analysis or image processing can be used to facilitate human/computer interaction.
