Sensors (inputs)

$let\ c = [list\ of\ column\ height]$

$let\ k = length(c)$

Peaks : $$c_{n}$$

Height : $$Max(c_{n})$$

Relative Height : $$Max(c_{n}) - Min(c_{n})$$

Roughness : $$\sum_{n=1}^{k} \left ( \left | c_{n}-c_{n+1} \right | \right )$$

Differences : $$x = c_{n}-c_{n+1}$$

Holes : $$\sum_{n=1}^{k} \sum_{r=1}^{c_{n}} \left ( \epsilon(c_{n_{r}}) \right ) $$

$$ \epsilon (x) = \begin{cases} 1 & \textrm{if } x = 0 \\ 0 & \textrm{if } x \neq 0 \end{cases}$$

Total Height : $$\sum_{n=1}^{k} \left ( c_{n} \right )$$
