The Edge Map
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
State
Two-dimensional convolution is the same sliding move with a square template — the output is a map, one match score per neighborhood.
Show
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.
Watch for
Templates are orientation-specific — rotate the template and the same patch goes silent.
