%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. % % REFERENCES % 1.
