I have searched the answers for a long time to help me with this but I can not find it. I tried to do with drawing programs but it looks good.

How can I leave the "w" blank, respecting its shadows or reliefs, so that it remains the same as the "s" , without touching the "s"

  • $\begingroup$ @AccidentalFourierTransform hello, I would not know how to implement it, could you give an example please $\endgroup$

As a not too elaborated solution, it seems that a morphological image processing can be done:

procimg = DeleteSmallComponents[img, 140] // EdgeDetect[#, 1, 0.3] & // ColorNegate

enter image description here

  • $\begingroup$ wow thanks, there is some way to vectorize the resulting image, so it does not come out so pixelated, or to start from an image already vectorized $\endgroup$

  • $\begingroup$ @susydiaz your image is a bit small. It is normal that appears pixelated after processing. For vectorizing images you can use ImageGraphics. I suggest you read the doc about it. $\endgroup$ Jan 24, 2018 at 9:56
  • $\begingroup$ hello, and vectorize the image with an external program (wmf), as I can import a vectorized image, I get that format can not be imported. my idea is img = Command ..., then your code (* ImageGraphics is a command in my mathematica is not or is an external program *) $\endgroup$
