This page takes an image and attempts to create an ASCII-art derivative of it using an edge-detection algorithm. It works best for images with solid colors and hard edges.

File:

Debug Stage:			Check the output of different stages of the algorithm.
Blur Radius:			The radius of the Gaussian blur to apply to the image. Reduces noise but can lose weak edges.
Edge Threshold:			The most commonly-changed setting. Higher values will cause more characters in the output.
Dilate Radius:			Thickens the detected edges.
Erode Radius:			Narrows the detected edges. When used with an equivalent Dilate, cleans up noise.
SDF Blur Radius:			Higher values will cause more characters in the output.
Inverse Match Weight:			Penalty applied to characters that don't fit the detected shape as well. Higher values will cause less characters in the output.
