Patent number: 11928829Abstract: 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.Type: GrantFiled: September 21, 2021Date of Patent: March 12, 2024Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Hirotaka Sakamoto, Masao Yano, Tetsuya Shoji
