Download data and software zip (42MB) unpack, run scripts, and generate figures with a Python script.
Source codes of the program heps.cpp uses OpenCV 2.2 library. The data and software zip file contains Win32 executable.
Additionally we deliver HEPS ImageJ plugin which implements the method, however, gives slightly different figures (beacuse of e.g., circle generation algorithms in the libraries used).
Notes:
Original DICOM files can be found at Santec webpage, (im13-im19)
Raw image files contains 512x512x7 32 bit float data.
While using ImageJ please check weather Little-Endian byte order is used (and Edit->Options->Input/Output->Save TIFF and raw in Intel byte order is checked).
