Multiple Features Dataset: Pixel
One of a set of 6 datasets describing features of handwritten numerals (0 - 9) extracted from a collection of Dutch utility maps. The maps were scanned in 8 bit grey value at density of 400dpi, scanned, sharpened, and thresholded. Corresponding patterns in different datasets correspond to the same original character. 200 instances per class (for a total of 2,000 instances) have been digitized in binary images.

Using this dataset, sampled versions of the original images may be obtained (15 x 16 pixels).

Attribute Information

The mfeatures represent 240 (15 x 16) pixel averages in 2 x 3 windows.
