Hi Octave seems to take a really long time to imread most of my multipage tiffs. Sure, I'm talking about large ones, 2500 pages of 350x300 pixels, but still I think it's too long. More than 3 hours.
I picked one image and made substacks of it with different sizes. The time to read one image (one page, not the whole file) increased with the number of pages in the file, and seemed independent of the number of pages I wanted to read. That is, even if I only tried to read the first page of a file, if the file had many pages it would still take a long time. I hope it's clear what I'm trying to explain. Don't know if this can be of any help, but the software I use for a pre-analysis of my images (called ImageJ), it's free/open source (public domain license according to wikipedia) and takes little more than 4 seconds to read the same image that octave takes more than 3 hours. I'm not complaining how octave is bad in comparison to others! With my poor knowledge on the subject of programming, it just seems that maybe it could be a good place to look if someone ever tries to make it faster, without problems of licenses and in the good spirit of sharing knowledge/code.
