I've noticed that lots of masks slows down the preview, but everything generally works ok for the original intent of rough masks manually created in the GUI. Clearly your generated masks are pushing the limits, it would be nice to resolve these issues at some point, this should be a bug report. -- Bruno -- You received this message because you are subscribed to the Google Groups "Hugin and other free panoramic software" group.

[hugin-ptx] large masks considerably slow down nona
Hi group! I'm currently working on a script that relies heavily on masking. The script generates the masks to arbitrary precision. Most of the time I was using spacings of about 100 pixels for the masks, and all was well. Today, while testing, I generated much more precise masks. I set the spacing to one pixel, and this threw a spanner in the works when I tried to process the data with nona. I didn't wait for the process to terminate and tried with 10 pixel stride. This increased processing time by roughly 200%! So I made the test and made a single-image pto and put a 125-point mask on the image manually, just to be sure it wasn't some strange effect of my script. It took nona over 11 seconds to render the image. when I removed the mask, it only took 4.4 seconds. This was with a 12MP 16bit TIFF in stereographic projection, on Pre-Release 2010.5.0.a11acbf8be1d. I wonder if anyone else has noticed this? Has it been like this all along? Maybe I'm the only one using masks with more than a couple of dozen points? I've attached the .msk file which I used to slow down nona. Kay -- You received this message because you are subscribed to the Google Groups "Hugin and other free panoramic software" group.
