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, calculates a variation in pixel values of pixels included in the partial region. The information processing device, for each partial region in the image, determines a degree of crystallinity of the partial region based on the calculated variation in the pixel values of the partial region.
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, calculate a variation in pixel values of pixels included in the partial region;
- and
- for each partial region in the image, determine a degree of crystallinity of the partial region based on the calculated variation in the pixel values of the partial region, wherein:
- in a case of calculating the variation in pixel values, the processor is further configured to calculate the variation for each of the partial regions, each of the partial regions representing an image within a predetermined range centered on a center pixel;
- and
- in a case of determining the degree of crystallinity of each of the partial regions, the processor is further configured to determine the degree of crystallinity of the partial region by determining a degree of crystallinity of the center pixel in the partial region based on the calculated variation for each of the partial regions.
An information processing method in which a processor executes processing, the processing comprising:
- acquiring an image captured by a transmission electron microscope;
- for each partial region in the image, calculating a variation in pixel values of pixels included in the partial region;
- and
- for each partial region in the image, determining a degree of crystallinity of the partial region based on the calculated variation in the pixel values of the partial region, wherein:
- in a case of calculating the variation in pixel values, the processor is further configured to calculate the variation for each of the partial regions, each of the partial regions representing an image within a predetermined range centered on a center pixel;
- and
- in a case of determining the degree of crystallinity of each of the partial regions, the processor is further configured to determine the degree of crystallinity of the partial region by determining a degree of crystallinity of the center pixel in the partial region based on the calculated variation for each of the partial regions.
A non-transitory recording medium recorded with an information processing program executable by a processor to perform processing, the processing comprising:
- acquiring an image captured by a transmission electron microscope;
- for each partial region in the image, calculating a variation in pixel values of pixels included in the partial region;
- and
- for each partial region in the image, determining a degree of crystallinity of the partial region based on the calculated variation in the pixel values of the partial region, wherein:
- in a case of calculating the variation in pixel values, the processor is further configured to calculate the variation for each of the partial regions, each of the partial regions representing an image within a predetermined range centered on a center pixel;
- and
- in a case of determining the degree of crystallinity of each of the partial regions, the processor is further configured to determine the degree of crystallinity of the partial region by determining a degree of crystallinity of the center pixel in the partial region based on the calculated variation for each of the partial regions.
