Data : Left Hands

Description

This dataset contains 10 shapes of 4 subjects's left hands where each shape is represented by 56 landmark points. For each person, first six shapes are equally spaced sequence from maximally to minimally spread fingures. The rest are arbitrarily chosen with two constraints; (1) the palm should face the support and (2) the contour should contain no crossins.

Usage

data(hands)

Format

a named list containing

data: an (56\times 2\times 40) array of landmarks for 40 subjects.
person: a length-40 vector of subject indices.
