Computation of Imaging-Based Science

All visitors are welcome to join the next meeting of the Computation of Imaging-Based Science seminar.

2:30: Yongseng Pan:  I will present recent advances on high-resolution tomography reconstruction at beamline 2-BM-B of Argonne APS. First, a rotational axis localization method is proposed based on cross-correlation, which enables fully automatic reconstruction. Second, a ring-artifact removal algorithm based on image inpainting techniques is proposed for accurate reconstruction. Third, a framework is proposed to integrate a data exchange format for efficient data access, GPU for efficient reconstruction, and iterative reconstruction methods (SART and EM) for limited-view tomography. These combined advances make 2-BM-B more powerful for user support.

4:15: John Reinitz: Fundamental biological processes such as the determination of the body plan and transcriptional control require quantitative measurements of gene expression at cellular resolution in space and a few minutes resolution in time. We have been acquiring these data from early embryos of the fruit fly Drosophila. I will summarize the problems faced in this enterprise, how they were solved, and what general conclusions can be reached.
