I have this image kindle.jpg, while trying to simplify the image for better OCR results, I noticed that it gives different results in version 6.7.8-9 2019-02-01
vs latest version 7.0.8-53
The same command I am trying on both results below is:
Code: Select all
convert ocr_test/kindle.jpg -fill white -colorspace gray -threshold 20% temp/test.jpg
Also with both versions I see no difference if I specify -fuzz 5%
or -fuzz 90%
is this a bug ?
converted with 6.7.8-9 2019-02-01

V6.7.8 is very very old, and had some peculiarities.
"-fuzz" is a setting that affects the behaviour of some operations (eg "-opaque"), but you don't use any of those operations.
