[Bug 720556] Re: Blend fails with mask entirely black.

 

I followed the hint and manually removed two images that overlapped a lot with other ones and it works now.
Still, in that case enblend could ignore an offending image completely (but throw a warning). Instead, no result image is written and the error message does not really help.

suggestion 1: include a more informative error message (offending image
pairs, hint to remove one of the images)

suggestion 2: enblend could ignore all offending images (e.g. use the
first one of a largely overlapping pair)

Title:
  Blend fails with mask entirely black.

Bug description:
  I get the

  enblend: warning: failed to detect any seam
  enblend: mask is entirely black, but white image was not identified as redundant
  enblend: info: remove invalid output image "t2.tif"

  again.

  The issue here is that I cannot just remove the offending image,
  because I have some interesting features in this image that need to be
  included in the final photo. The pano I'm building is a sequence of
  photos of a moving object, and indeed the fourth frame of the sequence
  mostly overlaps the third, but important image-data is included on the
  fourth frame that I have marked with a "include this mask" in the
  masks tab....
