Clean shadow around text

[dattatembare]

I'm using IM:ImageMagick-7.0.7-Q16 on Windows
I have processed an image(https://www.dropbox.com/s/eqm7wgd8bbeqb ... l.png?dl=0)
using

Code: Select all

convert original.png -brightness-contrast 5 -depth 8 -quality 100 -morphology Smooth Ring:1 result.png 

I have a shadow around my text, I want to make it clear so that tesseract can return exact text.

Result image is like - https://www.dropbox.com/s/0k10yfllltmf1 ... t.png?dl=0

I tried -sharpen 0x2.0 and -unsharp 25x25, but didn't work

You will need to post your images to some free hosting service and put the URLs here. This forum does not allow direct image upload/storage.

What is your Imagemagick version and platform?

@snibgo Thanks! for notes
@fmw42 I have updated my original post

[fmw42]

try

Code: Select all

magick original.png -threshold 50% result.png

Adjust the threshold as desired to potentially improve the result.

After using

Code: Select all

convert original.png -threshold 50% result-4.png

Result is poor than my original script https://www.dropbox.com/s/yuxg42kz595f4 ... 4.png?dl=0

My result is better than the link to your result in your original post at the top. Your latest link does not look like the result you originally posted.

I have no other suggestions to offer.

I didn't get you what you mean.

I tried

Code: Select all

convert original.png -depth 8 -quality 100 -morphology Smooth Ring:1 -negate -lat 25x30+20% -negate result-6.png

and result is much better.

My result was better than your original result that you posted at https://www.dropbox.com/s/0k10yfllltmf1 ... t.png?dl=0. Perhaps you have found a better method than your original post and even my method. Or perhaps your original result was an incorrect post, since it looks much like the source image.
