Hello everyone. I am working on a certain project and I need a tool similar to the Photoshop Quick Selection. Could you tell me which algorithms are used here? (Maybe at least a hint)

Could you show us what exactly you are trying to do? And maybe why the Quick Selection Tool is NOT doing what you need...?

Are you asking Adobe to give you proprietary design / code information for software that you are developing? What is that "certain project?"

Steve Kenny I need to automatically detect the borders of objects (like parts of body) for cropping. I trying to use openCV methods such as finding contours, but it don't work so well.

Dave Grainger I can't tell you what is the project about, but I don't think that it will make a competition to Adobe :)
I ask at least about the names of the algorithms, if they are publicly available.

Hello there Bratyslav,  

If you are talking about the "Open Recently Edited File" in Adobe Elements, this follows the same coding as any program launcher but also follows the "last known good" in NT Windows of years prior to- Windows 7 and 10. 

The "Last known good" was a Windows-thing to open your OS to its last known configuration as a way for a tech to know what took place in the last session and to continue from there to know what the problem is, if in case there was one. 

This was the same place where you left off at in your previous session.  At the end of your last session, you can continue without missing a beat as Windows boots u p to this each day automatically.  

In Adobe, its the same way, thereby, it will bring up the same file(s) so you can continue your project as you describe.  Under the FILES heading will be "Open Recently Edited File", as your last known project.  You won't need any codes because Windows has those each day anyway.  

The codes in Windows for this is to press F8 and hold it down while Windows starts but upon doing this, your OS launch will be delayed because that program is already in your boot up process.    Technically we call it the LKGC - "Last Known Good Configuration". 

So you don't need the codes for it, as it will mess up Windows to delay your program.  It loads the last known drivers you had during your last session and also loads the same files as before, even if you deleted them, and this especially confuses the user.  Adobe doesn't do all of this but it will keep your recently files handy for you to select.  Hope this helps a little.   

Steve Lehman, mcse

I think he was asking about Quick Selection Tool within Photoshop, near the Magic Wand Tool and other selection tools rather than selecting a program state....
