the code does not implement the robust merge?
whqwill opened this issue · comments
I stored the dng file after the "merge" step and found that shaking hands and shaking leaves were always ghosting, although every picture in my original dng file has no motion blur. This phenomenon is not as described by the author in his blog. I suspect that the robust merge part of the code is not implemented well. Isn't it ? @timothybrooks
Yes, you are correct. Please take a look at my writeup, which precisely explains the algorithms I use. I made many approximations and omissions to simplify the code, one of which was to use a naive patch similarity weighting rather than the robust DFT Wiener filter.
I am closing the issue because it is working as intended for my implementation, and I have no plans to implement the Wiener filtering. However, if you are interested in improving on this, you are more than welcome to submit a pull request for a better merge.
