Hi , I have emailed images in 3 parts. Please have a look at it.
For CP generation I tried panomatic. Its very fast But It generates error for this number of pictures. Autopano sift also generates errors but %p %o %s parameters have fixed this issue. Is there any special parameters for panomatic? I dont know how to use command line panomatic so that I can check it. Autopano giga is fast but I dont need speed. Hugin Image quality is best among all other stitching softwares. So all hugs for hugin :)) On Thu, Aug 26, 2010 at 5:18 AM, Yuval Levy <[email protected]> wrote: > Hi Emad, > > where have you uploaded the pictures and replied in detail?
