I have some black and white photos from my wedding and I want to add some colour to them.
There is this paper from 2005 that allows you to recolour image by just painting stripes.
There is a standalone implementation here although it wasn't that great.
And Recolored allows you to just roughly choose your selection then it uses some algorithm for edge detection to make the correct selection. Although there is a 21-day trial, I have not been able to contact the authors.
Are there any other applications that can recolour in such a straightforward way (i.e. the software does edge detection instead of you having to spend ages selecting the regions manually).
