[hugin-ptx] multiple image composition for noise reduction

2013-08-29 Thread Mauro Torrez
Hello all, I'm trying to compose/overlay multiple photos taken with a compact camera into one single output image. Source images are very similar, taken with a handheld pocket camera and consequently slightly misaligned. My goal is to transform them so they all 'match' and blend/average them

Hi Mauro, I tried your images here and also didn't achieve a good result with align_image_stack, but finally got a good result with higin. Here is the final images aligned in a gif animation and the PTO file I used: https://docs.google.com/file/d/0BxAahc2X9ZVXVnBuOXdBR2w3ZUU/edit?usp=sharing

Ok, perfect! But just to mention: I tried without it before and with it I achieved a better result. :) The relevant aspect for doing this, IMHO, is that he shot handheld and it caused differences between images that can be better solved with different lens distortions for each image. I use to do

I forgot to say that you first need to create a New lens for each image (the ones you intend to stretch) to be able to make the lens parameters diverge. /John -- A list of frequently asked questions is available at: http://wiki.panotools.org/Hugin_FAQ --- You received this message because

You should always use a tripod to avoid parallax errors (ghosting). Even then, it will sometimes shift slightly after adjusting it so images are sometimes misaligned by one or a few pixels. You can often get away with shifting (translating) them in Photoshop or similar but Hugin will usually

You definitely should use a tripod to reduce parallax but more importantly you should understand the entrance pupil for your lens. This is the point in the lens that you should be rotating about so there is no parallax. Do some research on the web to better understand this requirement. On

Ok, perfect for a panorama, but this was not a panorama. Don't know exactly what he tried to do, but looked like he tried something like a time lapse or enfusion/HDR, for which rotating using the NPP would be useless, as in fact any rotation :) so any tripod would solve and also make alignment
