Re: [hugin-ptx] Why is part of the stitched image black?
That's helpful. I tried the option you recommended on several panoramas that had the black area or areas showing in different places and it solved them all. The only comment I would make is that in the most difficult of those stitches, on which I concentrated the most, it left a vestigial stitching flaw in a straight line that did not appear when I used the built-in stitcher. But that had its own similar small flaw elsewhere, so you have to take your pick as to which you prefer.

Have you tried the enblend command line option --primary-seam-generator=nearest-feature-transform For me this normally solves the problem. Methinks the bug is sitting in the graph-cut (now default) seam finder algorithm.

[hugin-ptx] using Hugin to flatten 3d fisheye image
is it possible to take a single fisheye image, convert it to equirectangular, then apply those exact same setting to another image? -- A list of frequently asked questions is available at: http://wiki.panotools.org/Hugin_FAQ --- You received this message because you are subscribed to the Google Groups "hugin and other free panoramic software" group.

There is no need to copy the masks.

[hugin-ptx] Re: Other multi-image techniques?
It is possible to create an image like this without blending the moving object with the background. Draw a mask around the object on the 1st photo, copy the mask to all other photos, then delete the mask from the 1st. The same for all images. At the end check if the masks don't overlap.

Re: [hugin-ptx] How to map a pixel (x,y) at a original image to the pixel (x_p, y_p) at the generated panorama by using some specific function or API?
Dear Sir, Thanks a lot for your help. Your informative answer perfectly addressed my issue. Thanks again. By the way, may I have your gmail, you can send me by private reply.
