Okay, apologies in advance for the high density of unknown information.
I read of a problem that some implementations of this technique have (YouTube video id b39R8eHyvmw), and I'm wondering if Liquid Rescale has sidestepped this problem, or if it should become a feature request.
Here's the text:
(the video's program appears to not…)
"get hung up in any spots, and continuously remove from the same seams.
I've seen a few people try to write their own image carving before… and they usually make the mistake of 'real time' carving, which generally gets hung up on the same seams over and over.
Do you use the seam ordering method described in the original idea? (Caching seam pixels in order of removal, before removing any seams.)"
My eyeball of one video that may not be of the same program, (I'm not sure, check yt id TDZc3HnKp8o says "yes, this is a problem" but I'm a newb to the whole subject.
It may also only appear to be a problem in the video due to image features (painted line) that make it easy to detect distortions, and the use of the "delete" option may bias/require the lines removed to be near that object for awhile.
I only found a few videos of the Gimp plugin, and none of them in real time like this vid of the original method: vIFCV2spKtg.
And lastly, video questions. It doesn't seem possible yet to use a GIMP plugin with VirtualDub, and it sounds so hard I won't ask. Can this plugin work in batch mode? And, most-highly-speculative-question is, is this technique (find lines of least energy) feasible in reducing video filesize?
