Abstract :
Gigapixel-size images are used in calculations on parallel machines using the Pacific Northwest National Laboratory (PNNL) Parallel Computational Environment for Imaging Science (PiCEIS). The PiCEIS image browser allows the user to view real-time images as calculations are performed. The user can interact with the images, assign regions of interest to accelerate feedback, and alter algorithm parameters. The images may be displayed on an X11 terminal or parallel compositing hardware. The fast feedback and interactive features available within the image browser component of PiCEIS are valuable tools for imaging science.
