Abstract
An information processing device acquires an image captured by a transmission electron microscope. The information processing device, for each partial region in the image, executes a two-dimensional Fourier transform on an image of the partial region. The information processing device, based on results obtained by executing the two-dimensional Fourier transform on each of the partial regions, performs clustering of frequency strengths obtained from the results of the two-dimensional Fourier transform. The information processing device determines regions of different crystallinity in the image, based on results of the clustering.
Claims8
An information processing device comprising:
- a memory;
- and
- a processor coupled to the memory, the processor being configured to:
- acquire an image captured by a transmission electron microscope;
- for each partial region in the image, execute a two-dimensional Fourier transform on an image of the partial region;
- based on results obtained by executing the two-dimensional Fourier transform on each of the partial regions, perform clustering of frequency strengths obtained from the results of the two-dimensional Fourier transform;
- and
- determine regions of different crystallinity in the image, based on results of the clustering.
An information processing method in which a processor executes processing, the processing comprising:
- acquiring an image captured by a transmission electron microscope;
