The Edge Map

The idea
Two-dimensional convolution is the same sliding move with a square template — the output is a map, one match score per neighborhood.
In practice
A four-by-four patch, dark left, bright right, swept by (−1, +1): the middle column spikes at 9, the rest sleeps at 0 — vertical edges, mapped.
Where people slip
Templates are orientation-specific — rotate the template and the same patch goes silent.
