Software to combine images?

Using the MD script I've got a few series of photos of birds at my feeder.

I think I've seen software that will let me stack the images and get a bunch of birds from different shots in the same frame.

I can find stacking software to combine focus bracketed shots; HDR stacking; tourist removing. . . is there a name for what I want to do? [I've tried photoshopping it by just lassoing the birds & copy/pasting, but it is tedious because my eyes are weak and my hand is not steady.]

Thanks,
Jim

I am not sure what you want to do.

Is it compositing ?

Is it mosaicing ?

I think the effect you're after can be achieved in most image editing programmes - more than likely even the free ones.

Would probably just be a case of masking the parts of an image you want to reject and leaving the birds in so that they'll all appear on the single image?

http://www.tawbaware.com/is_help/imgstack_help.htm - may be worth trying that, not sure if it'll get the effect you want though?

After having a bit of a play/look on the internet, these would probably do fine for you:

I know what you want to do but can't quite think of the best way to go about it - the above will probably get the result you're after, it's just probably not the quickest.

Best of luck finding the programme - I seem to remember a similar one, may have been an astrophotography programme. Let me know what you end up with/if you find a programme designed for what you're after

I think you are looking for Multiple Exposure photos.

While it is somehow possible with some high-end cameras (I think), you can do this by cropping out photos.

You should maybe have a look on ImageJ (http://rsbweb.nih.gov/ij/). ImageJ associated to hundred of scripts and plugins
will allow you to handle nearly any project in the frame of image analysis/Still and video images processing.
Many of those pluggins are profesional grade java developpement, well documented and easy to use.

Most of them if not all are free, and imageJ too is free, under constant development
The user forum is very useful for finding solutions and very responsive to new problems
(https://list.nih.gov/archives/imagej.html)
Don't be afraid by the dominant image analysis questions. Many of the scripts or pluggins are very usefull in photography/photomacro and micrography

Among my favorits are:

MosaicJ (http://bigwww.epfl.ch/thevenaz/mosaicj/) stich together multiple fields in near any shape and picture number with a precision which is difficult to reach by hand

Stackreg (http://bigwww.epfl.ch/thevenaz/stackreg/) realign precisely pictures taken with slightly different position. Can even realign pictures from the same point of view, taken at slightly different zoom factors.

Extended Depth of field (EDF) (http://bigwww.epfl.ch/demo/edf/) build a stack of pictures with several level of focus plane and extract a single picture with all "in focus" pixels. A kind of virtually infinite depth of field procedure in photography/macrophotography. For best results, use Stackreg first.

Most of those plugins can be scripted with a simple macro recorder, allowing to organize automated workflows processing
any number of picutures in batch overnight

That looks promising. I'll have a go at it.

That might be the ticket. I just need to think of the individual birds as seperate pieces of a mosaic rather than as part of a larger image.

Thanks to all- and especially Guy.
