Usage

olivetti_faces()

Format

A data frame with 400 rows and 4097 variables.

Value

The Olivetti Faces dataset as a data frame.

Details

Returns the Olivetti Faces dataset in a data frame reformatted to have one face per row, rather than column. This is a series of 400 images (with dimensions 64 x 64) of 40 individuals' faces, with ten different poses per person.

The variables are as follows:

  • px1, px2, px3 ... px4096 8-bit grayscale pixel values (0-255). The pixel index starts at the top right of the image (px1) and are then stored column-wise.

  • Label: An integer in the range (1-40) indicating the person.

Each row has a name with the format face_pose, where face is the index of the face, and pose is the index of the pose, e.g. the row with name 20_10 is the tenth pose of the twentieth face.

Note

Requires the RnavGraphImageData package to be installed.
