Detailed Description

An Optimized Image class (but only for very small images).

This class provides functionality and data for analyzing features of tiny images (size 16x16 or less).

One bit is used to represent each pixel, and is either on (black) or off (white). Information about each row and column is maintained, including the number of holes and the number of black pixels. This information will hopefully allow for the implementation of efficient methods related to feature extraction.

The 'str' method is a useful debugging tool that shows the information maintained within an instance of this class in a very concise fashion. An example of the output for the call: optim->str('#','.',7) will be 0111110 0 #...... 1 0 #...... 1 0 #...... 1 0 #...... 1 1 #.###.. 4 1 ##...#. 3 1 #.....# 2 1 #.....# 2 0 .#####. 5 8222222 assuming that 'optim' represents the 'b' shown. The numbers around the borders are interpreted as follows:

• left border = number of holes in this row
• right border = number of black pixels in this row
• top border = number of holes in this column
• bottom border = number of black pixels in this column

IMPORTANT: A "hole" in a line is a sequence of contiguous zero's (off or white bits) enclosed in 1's (on or black bits) on both ends.
