Abstract
At least one storage stores a dictionary of a discriminator acquired by machine learning by use of a plurality of pairs of crowd state image as an image which expresses a crowd state at a predetermined size and includes a person whose reference site is expressed as large as the size of the reference site of a person defined for the predetermined size, and training label for the crowd state image. At least one processor extracts regions from a given image and recognizes states of the crowds shot in the extracted regions based on the dictionary.
Claims20
A crowd state recognition device comprising:
- at least one storage storing a dictionary of a discriminator acquired by machine learning by use of a plurality of pairs of crowd state image as an image which expresses a crowd state at a predetermined size and includes a person whose reference site is expressed as large as the size of the reference site of a person defined for the predetermined size, and training label for the crowd state image;
- and
- at least one processor configured to extract regions from a given image and recognize states of the crowds shot in the extracted regions based on the dictionary.
A crowd state recognition method,
- wherein at least one storage stores a dictionary of a discriminator acquired by machine learning by use of a plurality of pairs of crowd state image as an image which expresses a crowd state at a predetermined size and includes a person whose reference site is expressed as large as the size of the reference site of a person defined for the predetermined size, and training label for the crowd state image;
- and
- at least one processor extracts regions from a given image and recognizes states of the crowds shot in the extracted regions based on the dictionary.
A non-transitory computer-readable recording medium in which a crowd state recognition program is recorded, the crowd state recognition program causing a computer comprising at least one storage storing a dictionary of a discriminator acquired by machine learning by use of a plurality of pairs of crowd state image as an image which expresses a crowd state at a predetermined size and includes a person whose reference site is expressed as large as the size of the reference site of a person defined for the predetermined size, and training label for the crowd state image to perform:
- extracting regions from a given image and recognize states of the crowds shot in the extracted regions based on the dictionary.
