GIMP :: Seeking Better Green Screen Method

Jan 17, 2012

Gimp 2.6.6 on Ubuntu Linux 8.04.Scanning using VueScan Professional 8.5.20 with an "Epson Perfection 4490 Photo" scanner. Color profile has been built for the scanner using available photo color target from a well-known German source (can't remember name).Almost all my scanning is of postage stamps and related items -- scanning the actual physical objects, not photos of the objects.

Problem:

The stamps are currently scanned on a black background (for lack of other color possibilities; the final goal is on a black background). After scanning, the background is selected and turned to 100% black to have greatest contrast for the object. When a stamp has a postmark that crosses the edge of the stamp paper, the color of the postmark (usually dark or black) is very close to the color of the scanning background and thus when the background is selected, the selection "leaks" and "follows" the postmark onto the stamp. We have to manually exclude those "leaks" from the desired selection area.

Goal:

To be able to select the background (for change to 100% black) without any "leakage" of the selection onto the stamp objects AND without ANY non-black color artifacts remaining after changing the selection to 100% black.

Attempted Solutions:

We have tried scanning on many different non-black background colors and surfaces, but there are always some extreme-edge color artifacts remaining ... leaving a sort of "halo" effect around the stamp object.Some of this could be attributable to the particular model of scanner, though every scanner I have ever owned had a similar problem to a greater or lesser degree. The width of the "halo" usually depends upon which side of the object it is on vs the direction of travel of the scanner device.

In television broadcasting it is extremely common for somebody to stand in front of a "green screen" and for the green to be electronically replaced with some image or video, etc. (For example, the weather person standing in front of a weather map.) It is rare to see a green "halo" if everything has been done correctly and if the person is wearing the correct type of clothing fabric.

Is there some Gimp method or plug-in or other tool that will better handle this type of use?Recently poster Ron Guilmette discussed his use of "Darla-PurpleFringe.scm" plug-in to remove an artifact caused by a digital camera and subsequent processing.

Is there something like that which can be used to remove a color "halo" that results from using a "green screen" approach to scanning? (I would likely have to select different colors of "green screen" so that such colors are not included in the design of the postage stamp.

GIMP :: How To Remove Green In Green-red Leaf

Aug 31, 2012

I've attached a leaf image. We'd like to "Autumnize" the leaf even more and remove the green from the leaf. I've tried playing with the various options in the Color drop down (Color Balance, Hue Saturation, Colorize, Brightness-Contrast, Threshold, Levels, Curves), but I can't seem to do it.

AutoCAD .NET :: Redrawing Screen During Execution Of Command Method

Dec 19, 2012

I would like to be able to have the screen refresh periodically to show the new objects I have added as a command method proceeds to execute. I am hoping to be able to achieve a kind of simple animation by doing this, and also to show progress while a computationally intensive operation is under way. Is there a way that I can do this? 

I have tried using AcadApp.DocumentManager.MdiActiveDocument..Editor.Regen() and also .Editor.UpdateScreen(), but it only seems to work once and not multiple times. Do I have to commit the transaction and then .

Photoshop :: Method For Designing Icons For Screen Usage?

Aug 5, 2004

I have an upcoming job which requires me to design a series of icons for screen usage (32x32 pixels). I've had plenty of experience designing icons and logos for print, and would appreciate some tips on the method for designing them for screen.

Is the process just a matter of designing the logos in a vector program, importing them into a 72dpi PS file (32x32 pixels), and then optimising the file in Image Ready? (batch process?).

Photoshop :: CS3 - Removing Green Screen?

Oct 6, 2011

I have a new customer who sent me a few hundred images which one of his employees shot against a green background. It would be easy enough to remove the background, but the green is reflecting on lighter colored products (Like a gray sweatshirt) and some of the pictures are of transparent items, (like a clear, plastic cup, or a product in a clear, plastic bag).

He claims that Photoshop (Which he admitedly knows nothing about) has a "Chroma Green Remover" - You just wave your magic wand and the green disappears. He also claims that he used to send his images "overseas" to have this done and they came back in a matter of an hour or two.

I have been using Photoshop since version 3.5 and have never heard of such a technique (Using CS3 now). Is there a way to do this, or should I have him re-shoot the pics?

Paint.NET :: Editing Green Screen / Layering?

May 21, 2012

When I open up the image that I want 2 use 4 my background the image fills the (working) window. Then, as instructed, I go in2 "Layer" & import the pic w/the green screen background. But when I then go 2 "Effects" & choose/use ChromaKey (again, as instructed) the background pic is now only a small square in the upper left hand corner of the window & the rest of it is white. Therefore, my pic/finished result has a background w/a little square in the upper left hand corner & the rest is white?

VideoStudio :: Overlay Track - Jagged Edges In Animations With Green Screen?

Jul 14, 2013

VS6 Ultimate
Windows 7

I am trying to render some small animated clips to be used as overlays in home movies. I am animating in a program called Poser. I animate 30 to 60 second clips rendering them over a green background (0 blue, 0 red, 255 green) and output them in Uncompressed AVI at 1280x720. When I bring them into VS6 they look great on track 1 but when I put them onto an overlay track they suddenly 'go small'; I right click and change to 'Project Size' (which I have set to 16:9) and apply the Chroma Key; this is where I begin to get the Jagged Edge effect? Especially on anything with a straight edge - for example: I have a Skull and Crossed Swords that I want to spin 360 - the sword edges become so horribly jagged, it just is not acceptable.

However, still using Poser as my 3D rendering engine, I can render a still and save out as a PNG and it will import into VS6 and overlay (as a Still) just fine. I did try rendering Each Frame of the spinning skull as PNGs and assemble the animation in VS6 and again I ended up with the jagged edges...even if this did work it would not be do-able with my 6sec clip of a waving flag (too many frames!)

Perhaps my AVI aspect size to VS6? I notice that while in VS6 I am working in only 720x480 however my final target is to burn to DVD in Wide Screen (I also would like to have MPG and/or AVI to play direct from computer on home entertainment system to TV)

A little background: I do historic reenacting at various events, shows, parties, Tall Ship events, Ren Fairs, and such. The overlays I want for various use: Title effects, overlay photos/videos within the project. Video files come from my Sony HDR-CX430V, photos from Canon SD790IS.

AutoDesk Smoke :: Green Screen On Window With Tracing Markers - Putting Reflection Back

Jan 12, 2012

I have greenscreen footage, where a green screen was put on a window with tracking markers. A person is moving in front of it, so you can see the reflection. If I just key it and put a garbage mask around it, I can get rid of the green and the tracking markers, but how can i get the reflections back now? Cause if I just screen the original desaturated part back on, you can still see the tracking markers.... Is the only way to first paint over the markers and then screen it back on, or is there another way? I'm on Smoke for mac 2012.

GIMP :: Best Method For Time Lapse From Photos?

Aug 12, 2012

I'm trying to make a time-lapse video from pictures I took of my kid.

The photos aren't well aligned, so I had tried the jpegs as multiple layers. I cropped, rotated, and scaled each successive picture so that it would be best aligned with the previous one. I then tried saving as a gif. The colors were messed up due to the color conversion. If I could export as a video format, that would be ideal, then I wouldn't have to convert the colors and could compress the file. I'm using windows 7, 64 bit, and GIMP 2.6, GAP didn't seem compatible with windows 7.

There are quite a few photos that I'm aligning, so the layers method seems the easiest. There are other programs which could take the aligned pictures individually and put them together, but I'd need a way to export the layers as individual files.

Lastly, I'd like to see what "morphing" one picture to the next would look like. I assume that would depend on what method I use to put the photos together.

GIMP :: Cutting Out Background - Color Mapping Method

May 25, 2013

I have attached two images of a young girl. One image (the original) is the one with the busy background. The second image is the one that I have cut out. Now with the pattern I have inserted behind her, the image seems quite acceptable, but if it as a plain white background, there is still some areas around the hair strands that contain the bluish background. Also to get to the stage of my image, I had to delete some of the whispy hair strands to make it look acceptable.

My question is, do you think it is possible to cut this out any better. This was done using the Color mapping method, but I have tried a number of other methods, but cannot seem to keep the hair strands visible and still end up with some color contamination around them. Do you think you could try this image and see if it could be done better.

GIMP :: Color Adjustment - More Green

Jul 13, 2013

I modified the color on a photo and I need to do it again, but I can't figure out what I did the first time. Attached are before and after photos. The before is what I have to work with (a much smaller resolution that what I am really working with, but colors are the same) and the after is the desired result. The leaves with the red arrows pointing to them are much greener in the after than in the before.
