The are only ten digits: 0, 1, 2, ... 9. You can crop each to a sample. Then, when you want to find the digits in an image, you can sub-search the image for each sample in turn.

hi thanks but i use subsearch but this output a coordinate not output true or false and when the image dont recognize then output other rare cordinate magick compare -metric rmse -subimage-search -dissimilarity-threshold 1 circle4.png NUMERO0.png null: 2>&1

how i could use a command for print true or false

[snibgo]

Code: Select all

compare -metric RMSE -subimage-search -dissimilarity-threshold 1 r2.png r.png NULL:

8152.75 (0.124403) @ 32,20

The number in parenthesis 0.124403 is between 0.0 (the match is perfect) and 1.0 (the match is as bad as it gets). Write a script to find which of the ten digits has the best match.

when i do with diferent image appears 19967.9 (0.304691) @ 151,53d
19967.9 (0.304691) @ 151,53d
