[hugin-ptx] Re: Enblend: limiting minimum levels
I suspect Monkey was right - if that hack limits those levels from being
blended at all, it's pretty useless. I guess that would result in all finer
details being lost and only the lower frequency components being visible in
the image? Editing the masks by hand works but it becomes a lot of work for
more than a couple of images. The ideal solution would be if Enblend
somehow could determine when this treatment is called for and apply it
selectively along certain seams. The criteria in example image 1 could be:
when one image is more detailed than the other, turn this feature on for
that seam. Example 2 presents a greater challenge as both images have about
the same level of fine detail. Perhaps a straight per-pixel image
comparison taking spatial placement in consideration would do it, with a
threshold?:
foreach pixel in area of interest {
match += sqrt ((image1.red - image2.red)^2 + (image1.red - image2.red)^2 +
(image1.red - image2.red)^2)
if (image1.pixel != black) nonblacks1++;
if (image2.pixel != black) nonblacks2++;
}
avgblacks=(nonblacks1+nonblacks2)/2;
match=match/(avgblacks*441.672943); // Max vector length: 441.672943 =
sqrt(255*255 + 255*255 + 255*255 = 195075)
if (match > threshold) { turn feature on }
(That's how I compare images in my own utility PicStack that identifies and
merges similar images. It's somewhat superceded by Enfuse though...)

What you can do is use Enblend's --save-masks, blur the saved mask file(s), then blend again using --load-masks to use the blurred masks.

[hugin-ptx] Re: Enblend: limiting minimum levels
I may be getting my wires crossed but I don't think the change Chris has made will provide the effect John wants. What I think is being requested is more complicated than just limiting or forcing the number of levels, but actually requires blurring the top level mask, so that the dividing line isn't so sharp. I don't know the Enblend code but I do have a handle on the process, and I don't think there's a simple way of achieving it with parameter bashing.
