Re: [libcvd-members] homographies

Hi Farhad,

For applying a homography, there is a function in cvd/vision.h called "transform()" -- it is not in the documentation for some reason.

As for v4l I think you can use ./configure --without-v4l1buffer --without-v4l2buffer .

For using OpenCV you can get to the bytes in a SubImage using .data() .  The TooN classes like Vector and Matrix contain nothing but the data, so it is easy to use with some other library.

Hope this helps,

Hello all,

Sorry for newbie question, I am very new to libCVD. Got to hear about it from PTAM. Was wondering if there is a way/function to apply homography on images? Also I am getting errors while trying to install the library; from ./configure I get missing v4l1buffer v4l2buffer v4lbuffer. I have heard this issue arises because in newer releases of ubuntu they ditched v4l1 (I'm using ubuntu 11.04). And last question; is there a recommended way of using cvd and OpenCV together (image type convertion, etc.) I know using these two together doesn't make much sense but I thought maybe I can use some OpenCV code inside PTAM framework.

Thanks a lot,
