Claim 7:
8. An information processing method in which a processor, coupled to a memory, executes processing, the processing comprising:
acquiring an image captured by a transmission electron microscope;
for each partial region in the image, executing 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
determining regions of different crystallinity in the image, based on results of the clustering, wherein,
in a case of performing the clustering, the processor integrates frequency strengths obtained from the results of the two-dimensional Fourier transform and clusters values obtained by the integration; and wherein,
in a case of performing the clustering, the processor uses a predetermined vector compression method to compress higher dimensional vectors, which are values obtained by the integration, into lower dimensional vectors that are vectors with fewer dimensions than the higher dimensional vectors, and clusters the compressed lower dimensional vectors.
