%IMOX Handwritten character dataset, 192 objects, 8 features, 4 classes
%
%       A = IMOX
%
% Load the dataset in A. The features are the distances from a bounding box
% to the pixels of a set of handwritten characters 'I', 'M', 'O', and 'X',
% measured form the corners along the diagnoals and from the edge midpoints
% along the horizontal and vertical central axes.
