avim1968 Posted September 26, 2012 Share Posted September 26, 2012 Hi All I have pictures that have different objects over a canvas like/un uniform back ground. I need to remove that background without any part of the objects them self. I mange to get most of the background out using the magic wand , but i'm left with many random single/groups of noise pixels left in the picture since they were not captured with the magic wand. most of the time i can remove those using the eraser or use the selection tools with different shapes around the pixels and press delete. but those methods take lots of time, specially around a complex objects and as i'm getting near to them, i need to make my selections/eraser radius smaller and smaller. I have tried to use a plugin called "Reduce Noise" that i found , but it does not work. can some one tell me a faster way how to remove this noise pixels without any part of the objects? or can some one point me to a plugin that does this? a plugin that "scans" the image/selected area and remove all pixels that are surrounded by transparency in it? This would save me lots of work, and hours of seating removing pixels :-( thank you Avi p.s I can't always select only the object/s itself/them self and just move it/them to a new picture :-) p.s.2 maybe a plugin that the user can choose up to what size, a group of pixels, should be removed ? (i.e. giving the ability to save small image parts if needed) Quote "DDAP=Don't Drink And Post!" :-) Link to comment Share on other sites More sharing options...

nitenurse79 Posted September 26, 2012 Share Posted September 26, 2012 Would this be of use ? http://forums.getpaint.net/index.php?showtopic=5610 (anti-alias assistant) I have used it following a tute to remove a lot of bits left over Quote Link to comment Share on other sites More sharing options...
Djisves Posted September 26, 2012 Share Posted September 26, 2012 If I understood right, Avim is proposing something different: A plugin that would erase stray pixels but have no effect on areas with a large number of contiguous/touching pixels. Perhaps with a slider that would allow the user to set areas with a minimum number of touching pixels to be ignored. Quote Link to comment Share on other sites More sharing options...

Avi (but I guess it could be done even for surrounded by the background/foreground color in the color wheel, or any color when i think about it more, am I right??)

Rick Brewster Posted September 26, 2012 Share Posted September 26, 2012 Got an example of an image that could benefit from this?

pdnnoob Posted September 27, 2012 Share Posted September 27, 2012 An example could be an image where you just cut out an object and put it on a transparent background, but you missed erasing a few pixels that are just floating in the middle of nowhere, especially if they are close to transparent. A plugin that will delete stray objects like that would be fairly useful, then, because it can detect such objects better than you can. As of now, the workaround is to set the magic wand tolerance to 0 and click in the transparent area so the spots are outlined for you to see Quote No, Paint.NET is not spyware...but, installing it is an IQ test. ~BoltBait Blend modes are like the filling in your sandwich. It's the filling that can change your experience of the sandwich. ~Ego Eram Reputo Link to comment Share on other sites More sharing options...

I'll keep you updated. Avi Quote "DDAP=Don't Drink And Post!" :-) Link to comment Share on other sites More sharing options...
pdnnoob Posted September 27, 2012 Share Posted September 27, 2012 Much appreciated, avi! Before you get too far, here's some features you may want to add: 1. Transparency Threshold--allow the user to decide how transparent the spots are that will be removed 2. Radius--similar to above, but decides how big the spots are 3. Opacity--instead of just deleting the spots, maybe have a slider that decreases their transparency 4. Spots only--Used as a preview function so you can see what areas are being defined as spots. Should work the same way as the "edge only" checkbox in the "soften edges" plugin (Set the spots to black and everything else to white) Glad someone with coding knowledge is working on this! Thanks again, avi Quote No, Paint.NET is not spyware...but, installing it is an IQ test. ~BoltBait Blend modes are like the filling in your sandwich.

nitenurse79 Posted September 27, 2012 Share Posted September 27, 2012 This would be a plug-in well worth having. Hope to see it developed Avim Quote Link to comment Share on other sites More sharing options...

Hi Rick I would ask the permission of the owner of the pictures I'm working on/with if I can upload them to the forum. Avi I know Avim is working on this, but just so Rick understands what you are referring to there is a tutorial on here "Remove Tricky Backgrounds" which has an attached google doc with the actual tutorial. I believe what he was referring to is shown on the second or third step of the tutorial. https://docs.google.com/document/pub?id=1If-8y_QixkSAwKhbPP3QwZQgnY0TmIqZzsxgGL6non8 Quote Link to comment Share on other sites More sharing options...
DryToad Posted May 20, 2021 Share Posted May 20, 2021 If anyone stumbles on this topic searching for a plugin that does that, archip's Stray Pixel Remover works wonders. The Number e's Cluster Clear should do something similar too, but I couldn't make it work. Quote Link to comment Share on other sites More sharing options...
MJW Posted May 20, 2021 Share Posted May 20, 2021 Though this is an ancient thread, it does seem reasonable to add suggestions for those who might stumble upon it with a search, hoping to find a solution to the problem. In that spirit, I'll add that my Object Pruner plugin may be helpful in some situations. Quote Link to comment Share on other sites More sharing options...
DryToad Posted June 8, 2021 Share Posted June 8, 2021 Thumbs up on MJW's plugin, a plus is that it works for bigger clusters too! On that note, I just found out that G'MIC has several filters that help a lot with this kind of cleanup. Quote Link to comment Share on other sites More sharing options...
