Portugal banknotes signatures [solved]

5 posts • viewed 82 times

Hello everybody!

 

Recently I am working on the signatures of Portuguese banknotes for inclusion in the Numista database.

 

There are many different types of signatures and images with a white background are not easily found. Then, I managed to remove almost all of the colored backgrounds from the signatures, except for two of them, whose images are below.

 

Alberto Alves de Oliveira Pinto (Deputy Governor)

António José de Carvalho Brandão (Administrator)

 

Could someone more experienced in image editing be able to remove the background from these two signatures and help us with this? =)

 

Thank you in advance!

Vladimir.

Closing the topic due to lack of answers/help. Thank you anyway. =)

Better late than never I guess, here are some cropped versions to replace the colored ones in the database.

I used some higher resolution source material to make things a little easier.

 

Wow! One day I will have a skill like that with images! Thank you very much, @Idolenz !

 

I'm going to wait for some bugs to be resolved with the signatures that are already in the database and I'm going to request an exchange for the ones you sent me (of course, mentioning and thanking you).

I am still trying to make a tutorial, it's not very hard sometimes just tedious. The ones with easy backgrounds can be done in seconds, some very elaborate signatures on busy low contrast backgrounds can take 30 min.

The most important thing is to start with good quality source material, high resolution, sharp focus, ideally a format with little to no compression artefacts like png.
