Hi Monkey, verdandi has 2 blending modes:
- hard seam: this is the fastest one and relies to 100 % on Hugin photometric optimization. For me this works fine in about 3/4 of the cases. If there are bigger color/exposure differences at the image edges between the images then I use blend seam (or enblend) - blend seam: it uses the same seam finder as in the hard seam case. The remaining differences between the images are blended with a Poisson equation solver - something completely different from enblends pyramids approach. This algorithm can also blend away some higher color shifts between images. But it still benefits from Hugin photometric optimization - especially when the photometric optimizer has corrected the vignetting (color and exposure is not so important in this case). But I got some reports where verdandi blend produced bad results. This happens mostly when using bigger images. This issues are not there when reducing the output size. So it is very difficult to debug in the case. Fixes for this are always welcome ;-) Because of this issue and for backward compatibility I have hesitated to change the default. But each user can change the default blender in the preferences. PS: > Hugin may have done in balance the exposure of control points The control points are only used for geometric optimization. They have no effect for the photometric optimizer. Here only the current arrangement of the images is used for probing the photometric differences between the images. -- 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.
