As I understand it, enblend selects the seam width based on its determination of feature size -- the smaller the local feature size (the more detail there is), the narrower the seam.
The problem here is that when the feature size is anisotropic -- for example, the local features consist of long horizontal lines -- enblend doesn't pick the seam width very well. The attached image fragment demonstrates this. The local features are long, more or less featureless horizontal lines, so there's a lot of detail in the vertical direction but almost none in the horizontal direction. If a seam crosses these lines, enblend selects a narrow seam because there's a fair amount of local detail. The problem is that there isn't really much detail across the seam boundary. In this case, the horizontal lines were rows of waves in the far distance, so they moved between shots (there may also have been focus differences playing a part). I think that enblend should primarily at the detail perpendicular to the seam and ignore detail parallel to the seam. In this case, there's a fair amount of detail in the vertical direction, parallel to the seam, but almost nothing perpendicular to it. -- You received this message because you are subscribed to the Google Groups "Hugin and other free panoramic software" group.
