GIMP :: Remove Background Of Shadowed / Low-resolution Or More Complex Images
May 24, 2011
I am trying to create a network infrastructure diagram for where Iwork with Diagram.
For this I am putting into the diagram, images of: servers, switches,racks and so on. What I wish for those images is to have transparent background. So far, I've been able to find decent resolution imageswhich it's because I've started with the latest hardware.Here's an example, let's say for our Dell PowerEdge 6850 servers if found this: [URL] ....
which by fuzzy selecting the white background, with a threshold of15.0 and some selection subtractions I've been able to turn to: [URL] .... which is nice for what I wish to use it for.
Now, I've been able to handle some easy likewise situations but nowI've reached the vintage hardware and got bad results. Let me show an example image: [URL] .....
This is more difficult to make it look as I wish since it's resolution it's not decent and it also has a shadow effect which hardens a precise initial selection which can then be worked out to a better result.
After some efforts I either end up with a pixelized image or with a severely chopped image.
So, my question is how could I achieve the desired result for this and such images?

For quite some time I've been trying to find the best way to remove a white background from images. I've checked out the sticky thread on this forum and as my image isn't of great quality and because it features quite a lot of white that won't apply.
Recently I found this tutorial which is supposed to work great (as seen in the comments). However, I think that because of a GIMP update that won't apply anymore somehow. I was hoping you guys might know what was causing it.
Everything works well until I get to step 7, where I have to select to Alpha. There it selects just the outlines, but my selection includes inner parts of the image, not just the background. And then after I invert and delete, the white that remains still has transparent parts that show up on the upper layer. So, am I doing something wrong with the Alpha to Selection, is that tutorial updated or is there a better way to remove the background from ie. a logo with just one background colour which isn't of great quality.

I am trying to remove background from images using the 3 different selection tools. I start off fine, but ultimately the entire images keeps getting grabbed which ever tool I am using. It is easier if you are using a pro version of photoshop and not any of the elements versions? I have elements 11.

I am trying to create a form with a watermark image in Publisher 2013 and the text I want to overlay on the watermark is cut from an image I screenshot, so it has a white background, making overlaying a watermark impossible. There are boxes and bubbles and other items that I really do not want to re-create so that's why I am trying to do this first, before re-creating the entire forms from scratch.
Anyway, what I want to do is A. remove all of the white from the background (even in the spaces between the e's an B's and everything; yes I know it is insane, but I like things to be perfect) and B. I would like to darken the text. Currently is is almost gray-ish and I want it to be black.

I have this image: [URL].......
I would like to remove the background from that. I read few tutorials but they have one color(shades of color) background and quite good contrast. They make hair white and bg. black. But in my image some hair are black and some white and they overlap each other. I found great plugin to Photoshop named Topaz Remask 3, but I haven´t PS.

I have chosen to use the eraser with fuzzy edge to remove the background from a dog subject. I created an Alpha channel and made a copy of the original image as suggested in the tute. When I begin to erase it works for a few stroke then stops erasing. By trial and error I found that If I select back and forth between the original and the copy it will erase a little on each but this seems to be an irregular way of doing the job and this is not what the tutorials show. What I erase shows up on both the original and the copy, that is they compound the erasing. Should this occur? Why can't I complete the erasing on just one image. While it does achieve the removal of the background I feel I am doing something wrong.

How to crop a photo to remove the background? Or do I need to go through several of the general tutorials before I can follow a tutorial on cropping?
I found a bunch of cropping tutorials on YouTube, but they used a lot of advanced (to me) terms and seemed focused on difficult situations.
I have 30-40 photos that are of wooden figures cut on a band saw. They do not have highly irregular edges like hair or fuzz.
I am hoping for a tool that can automatically follow the outline and then let me make any minor adjustments that may be needed.

I'm looking for a technique for removing the background from an image similar to the way noise canceling headphones work.
Prior to shooting the portrait, we took a picture of the background and then, without moving the camera, took the portrait so that we were left with two images, one with and one without the subject.
Noise canceling headphones cancel sound by emitting a sound wave that is the exact opposite of the sounds they pick up from the outside. I'm wondering if there is some technique that could be used to make all pixels in the background a specific color (by mixing with its "opposite") to then improve the functionality of the fuzzy select or select by color tools.

I have a basic image and I just want to remove the background and be LEFT just with the image (i.e. No white background).
I have opened the image with Gimp and on this image I was able to "add alpha channel" which I believe needs to be done. Do I need to do anything after I add the Alpha channel?
This is what I did next:
The image is 100% and background 1.1mb. Select Fuzzy tool and position cursor over the background and click. The image and the image background have the moving dashes going around them.
Next I hit the delete key and the background goes checkered. Still there are the moving dashes around the image and the background outer square. Next I hit autocrop and I am left with a reduced checkered background around the image.
My question - what do I do from here. I just want the image with no background what so ever; also is there anything I need to do with saving too.
Previously I have saved this and when I go to use the image it appears to be much the same as the original with a white background.

I rebuilt my line on white background from Rich2005 and Ofnuts. My latest version is darker, smoother higher res and wider (see attached).
The problem now are stray pixels, many of them unattached to the line itself. I spent a lot of time with an eraser, but still haven't gotten them all. THERE MUST BE A BETTER WAY!
I found this excellent link on the subject. [URL] RobA even has a script to do what I want. However, I don't think it is GIMP 2.8 compatible, as I can't seem to find it to run it.

We are trying to make a little art project with my daughter for her school, so my wife went and took pics of each of the kids in her class making a "heart shape" with their hands. I have the backgrounds that will go behind them all complete, so I just need to extract the hands. Well, I thought I was being smart by purchasing a green piece of fabric to put behind them, but this has almost caused more of a hassle. In the original hand picture, you cannot really see the problem, but after extracting the hands from the original, there is all kinds of green that has bled into the skin color of the kids' arms.

I've tryed a simple colorize, but the result is not so good...

Basically I've got the cut out that I want to blend into a picture, and what I do is get the images as near the centre of the canvas as I can, then copy and paste a new layer. Take the new layer and reduce it in size by say 95%, then try to centre it within the original image behind is as best I can. Select round it with the fuzzy select tool, then delete the smaller image. Move back to the original image and then add mask layer and use gradient blur to introduce a gradually fading of a few pixels round the edges.
The trouble is this method is not really good for complex shapes and often involves some iWarping to get the smaller image within the boundary of the larger one. So my question is, is there an easy way to fuzzy select round an image boundary that can introduce an arbitrarily chosen margin, say 5 or 10 pixels?
Anyway this is the kind of thing I am working on at the moment, making trippy fantasy images using dead animal's skulls.

I am trying to create 48"x60" banners with text and high res images. Basically I am exporting a large 48"x60" .odt (open office) file as a PDF at 300dpi so I can then import it in to GIMP. When I try to import the pdf at 14400 (width), 18000 (height), & 30o resolution I get the following:
------
GIMP Message
Plug-in crashed: "file-pdf.exe"
(C:Program Files (x86)GIMP-2.0libgimp2.0plug-insfile-pdf.exe)
The dying plug-in may have messed up GIMP's internal state. You may want to save your images and restart GIMP to be on the safe side.
Gimp Message Opening 'C:UsersDUSTINDesktopWORKLR2 NO IMAGES.pdf' failed:
Procedure 'file-pdf-load' returned no return values
------------
The printing company is requesting my file be at 300dpi so that is why I am trying to import at 300 resolution. I am guessing this is a bug. My question is can I somehow just open the .odt file in gimp and add my high resolution images to it there? Is there a plug in for .odt in GIMP?

I am working on an anime picture. I want to have two of the same images, one larger, with no background, and transparent. The other will be just the image. I have that done, but how do I get rid of the checkerboard pattern, it's difficult to work with it in the way. Also, both images move together, how do I stop that from happening?

I have 33 images and each image has a white background. To make an animated .gif file I open the 33 images in GIMP 2.8.2 as individual layers and export as a .gif file. For some reason though, when it creates the .gif file, the background turns blue?

how to "drop out" the background from this photo (I have loads to do which are very similar). Thus far I have tried channel selections and the calculations tool + all the normal quick selection tools and I just cant get it to work without spending hours adjusting things. The end effect I need to achieve is a perfect white background without loosing any of the detail if possible. On a side note I have also tried taking the photo on blue, green, black and white backgrounds but due to the number of colours present in the products its just not working for me.

I have a problem with the display of background images in the viewport when using Nitrous display mode. Every image I load shows very pixelated and low-res. Then I switched to Direct3D and the image is crystal clear. Why is that? How can I make images in Nitrous show that clear? I tried modifying the 3dsmax.ini file but changing the texture limit values had absolutely no effect.

I used the magic extrator to isolate my subject in a high resolution picture (3000x4000 pixels). Then I put it on a background that I got off the Internet. It looked great on the screen, but when I went to print it at a photo store, the resolution was so low that I couldn't use the picture. I also don't know how to add a background any other way. Have others had the resolution of the picture degenerate to this point when it was put on a background?
