We develop a variational optimization method for crystal analysis in atomicresolution images, which uses information from a 2D synchrosqueezed transform(SST) as input. The synchrosqueezed transform is applied to extract initialinformation from atomic crystal images: crystal defects, rotations and thegradient of elastic deformation. The deformation gradient estimate is thenimproved outside the identified defect region via a variational approach, toobtain more robust results agreeing better with the physical constraints. Thevariational model is optimized by a nonlinear projected conjugate gradientmethod. Both examples of images from computer simulations and imagingexperiments are analyzed, with results demonstrating the effectiveness of theproposed method.
