Abstract
An image processing apparatus includes memory that stores a plurality of images acquired by image-capturing a face of a person; and a processor, coupled to the memory, configured to: acquire a pixel value pattern indicating a relationship between positions in a given direction and pixel values in an area having parts of the face of each of the plurality of images, and select an image to be processed from the plurality of images based on the pixel value patterns of the plurality of images.
Claims12
An image processing apparatus, comprising:
- a memory that stores a plurality of images acquired by image-capturing a face of a person;
- and
- a processor, coupled to the memory, configured to:
- acquire a pixel value pattern indicating a relationship between positions in a given direction and pixel values in an area having parts of the face of each of the plurality of images;
- select an image to be processed from the plurality of images based on the pixel value patterns of the plurality of images;
- and
- at positions of pixels in the given direction, calculate a statistic on pixel values from pixel values of a plurality of pixels aligned in a direction perpendicular to the given direction, acquire, as the pixel value pattern, a pattern indicating a relationship between positions of pixels in the given direction and the statistic, calculate a harmonic component in a frequency characteristic of the pixel value pattern as a characteristic value by using the pixel value pattern, and select the image to be processed based on the characteristic values of the plurality of images.
A non-transitory computer-readable storage medium having stored therein a program for causing a processor to execute a process, the process comprising:
- acquiring a pixel value pattern indicating a relationship between positions in a given direction and pixel values in an area having parts of a face of each of the plurality of images acquired by image-capturing a face of a person;
- selecting an image to be processed from the plurality of images based on the pixel value patterns of the plurality of images;
- and
- at positions of pixels in the given direction, calculating a statistic on pixel values from pixel values of a plurality of pixels aligned in a direction perpendicular to the given direction, acquiring, as the pixel value pattern, a pattern indicating a relationship between positions of pixels in the given direction and the statistic, calculating a harmonic component in a frequency characteristic of the pixel value pattern as a characteristic value by using the pixel value pattern, and selecting the image to be processed based on the characteristic values of the plurality of images.
A method of causing a computer to execute processing, comprising:
- acquiring a pixel value pattern indicating a relationship between positions in a given direction and pixel values in an area having parts of a face of each of the plurality of images acquired by image-capturing a face of a person;
- and
- selecting an image to be processed from the plurality of images based on the pixel value patterns of the plurality of images,
- at positions of pixels in the given direction, calculating a statistic on pixel values from pixel values of a plurality of pixels aligned in a direction perpendicular to the given direction, acquiring, as the pixel value pattern, a pattern indicating a relationship between positions of pixels in the given direction and the statistic, calculating a harmonic component in a frequency characteristic of the pixel value pattern as a characteristic value by using the pixel value pattern, and selecting the image to be processed based on the characteristic values of the plurality of images.
