I have a scanned copy of an old architectural plan of a building, it was done by hand is old and being a copy traced by crayon so you can imagine it is very fuzzy and speckled, there are clearly visible but no solid crisp lines.
It has taken me hours just to delete large areas of white space that is fuzzy/speckled.
Does anyone have any idea whether or not there is a function that can trace a line ignoring the fuzziness around it and making it crisp? I've been playing around with the magic wand tool but its not coping with it. Despeckle filter doesn't really cut it either.
Just don't want to spend hours drawing this whole plan up from scratch like tracing in Photoshop. Should I be using a Vector Graphic instead like Illustrator?
Any help appreciated.
I have heard that Illustrator has a dynamite tracing facility. I haven't tried it myself but there was a thread where we discussed cleaning up hand drawings and while I proposed a possible technique in Photoshop it was shown that Illustrator did a better job of tracing.
Ah, a bit of searching and I turned it up: http://forums.adobe.com/message/4720464
I suggest you post at least part of the scan that you want to trace. Ensure the posted file is a lossless export from Photoshop (i.e. a PNG if attached as a forum image) and is either the complete image or a crop with no resampling.
I was thinking just that conroy, attached is a crop of the type of the black and white scan I'm working with, this was originally a trace, it is a very large document this is just one part of it.
Thanks Noel I did mess around with your suggestions, not sure I achieved what I was after, it was either too strong removing everything or too weak.
What I'm trying to do is get rid of the speckle (despeckle filter cleans it a little) and just have all the lines nicely redrawn and crisp. I've so far being doing it manually but it is 1) inaccurate and 2) taking me a very long time.
While there are ways to get a cleaner looking image, there isn't an automated, off-the-shelf way to get the lines of a scan lke this "nicely redrawn and crisp."
Of course you have to weigh the importance of a perfect result agains the time it will take to do it manually, but if this was my project, I'd already have much of it redrawn (in vectors...in Illustrator), manually in the time you've taken to discuss it here. Redrawing the portion you've posted here would take me about 15-20 minutes, seeing as there are so many repeating elements that would only have to be drawn once using simple shapes, then duplicated across the facade of the buidling.
I agree with John Mensinger - draw it with vectors. I would not draw it with the Photoshop Pencil Tool as suggested by JJ. Vectors are resolution independent and easy to edit and stroke with various weights.
