A Hybrid CPU-GPU System for Stitching Large Scale Optical Microscopy Images

September 12, 2014
Author(s)
Timothy Blattner, Walid Keyrouz, Joe Chalfoun, Bertrand C. Stivalet, Mary C. Brady, Shujia Zhou
Researchers in various fields are using optical microscopy to acquire very large images, 10K--200K of pixels per side. Optical microscopes acquire these images as grids of overlapping partial images (thousands of pixels per side) that are then stitched

Author(s)
J F. Widmann, S R. Charagundla, Cary Presser
Control of process efficiency and the formation of species byproducts from industrial thermal oxidation systems (e.g., power generation and treatment of liquid chemical wastes), is generally based on a priori knowledge of the input stream physical and

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
