SynCrystal/SynCryst​al

Crystal image analysis

OVERVIEW
SynCrystal is a MATLAB toolbox to analyze atomic crystal images. For a given atomic crystal image, it contains several tools to identify grain boundary, crystal orientation, elastic deformation. A few examples of synthetic and real atomic crystal images are provided to illustrate how to use these tools.
INTRODUCTION
SSTmethod: A collection of MATLAB and MEX routines which applies 2D synchrosqueezed transforms proposed in [1][2] to analyze crystal images. Detailed description of this method is in [4]. An instruction for parameter tuning in the synchrosqueezed transform is in [3].

VarSSTmethod: A collection of MATLAB and MEX routines which applies a variational model to optimize the crystal analysis results provided by 2D synchrosqueezed transforms. Detailed description of this method is in [5].
