A new model of pulse oximetry: Two-dimensional pulsation

March 14, 2007
Author(s)
Shao Yang, Paul B. Batchelder, Dena M. Raley
We developed a two-dimensional pulsation model of pulse oximetry. Instead of a one-dimensional single layer as in the conventional theory, the arteries pulsate in two dimensions taking into account the effect of probing light that does not pass through the

Using Chebyshev Polynomials for Interpreting Structured Light Images

April 1, 1985
Author(s)
Michael O. Shneier, W Rutowski, Tsai H. Hong
A method is described of representing curved or line-like segments of images using Chebyshev polynomials. The advantages of the approximations include fast computation, minimum error over the sampling interval, and the reduction of the data to a concise
