Re: [hugin-ptx] Re: Masking inside hugin
Standard (negative) masking: Make sure that certain areas of a source image (a partial human body stepping into the frame, or parts of the panohead) don't make it into the stitched image while you have enough better background in another frame (e.g. a handheld nadir shot). The 'crop' tab is comparable but only allows to mask the outside of a rectangle or a circle. Positive masking: comparing two overlapping frames one feature might be in both but looks better in frame B.

Re: [hugin-ptx] What is hugin's best fit?
The mean and maximum errors you report are huge. They should, ideally, be less than one. You can find rogue points by looking at the CP lists associated with the image pairs. These lists can be sorted by clicking the distance header. Try removing those that exceed a distance greater than one and then reoptimise. Try setting up parallax correction manually using near and far objects, use the viewfinder first then try a few test shot pairs. In this instance I would rcommend that you start out producing a single row pano. You certainly don't need 30% overlap, 10%, or even less, should be fine. If you have a lot of overlap, Autopano will naturally create most points nearer to the image centre; and you simply waste image data and memory. Create all of your CPs by hand, concentrate your points near to the edges and corners (centre of the overlap region), twelve should be sufficient, then optimise everything. See how you get on, good luck. John McAllister -- You received this message because you are subscribed to the Google Groups hugin and other free panoramic software group.

This may be ok for cp generation, but the rest of the work flow would be hindered by it. One reason for more overlap is to allow enblend more room to create larger seams for lower frequency data. Another reason for more overlap is to give the photometric optimizer for datapoints to compute the response curves from.

Re: [hugin-ptx] Re: What is hugin's best fit?
If you sort out parallax, just roughly, then where in the picture you put your points, near or far, isn't too important; choose far. When choosing CP sites, just place your points practically nearest to the sides and corners of both images. I was wrong to suggest using the centre of the overlap area. Spread them into the area of overlap, as if they have violent charge. Think of the lever. So to bed. -- You received this message because you are subscribed to the Google Groups hugin and other free panoramic software group.

[hugin-ptx] Image overlap.
Image overlap - intererests me as a practitioner; and there is clearly plenty of experience out there. I have found that shorter lenses, with greater FoVs, tend to need greater overlap but this is to ensure sufficient overlap in the finished stitch, to reduce necessary cropping following perspective morphing. As an example of this, I use a 10mm lens with a HFov of 74 degrees (crop 1.6), turned through sixty degrees; an overlap of about 19%. I've built a lens profile so I only put in three points per picture pair - by hand; I get about 87 degrees vertically after cropping. Works every time, including exposure adjustment. I realise that Enblend needs some space because it follows edges, but I don't think the blending areas tend to be particularly large along those seams, it probably just uses the space conveniently available. Photometric optimisation, I understand this to mean exposure equalisation, generally defaults to 200 points of comparison. As an example, eight megapixel sensors would provide less than roughly 800,000 comparable pixels at 10% overlap. Surely, this is more than enough. I have recently been experimenting with a focal length of 50mm and I have found that I can pare the overlap down to about 5%, with good results. This reduces the number of pictures taken for a field of view. This saves time making a series - speeds up workflow - stitch and blend - reduces transport and storage. The major benefit from smaller overlaps is that Control Points are forced to the edges - whether points are made by hand - or not. I have achieved some very good and quick optimisations from very few handmade Control Point Pairs, without a lens profile, and small overlap. Small Overlap Movement. Here goes then...
