Hi,
Looking at the smooth routine in the dvsdk, it seems that de-interlacing is
accomplished by taking the first video field and then expanding it by 2x.
>From a comment in Smooth.c
/*
* Configure the IPIPE such that its input looks like a buffer half the
* height of the input buffer, and consisting of every other line in the
* input buffer. Smoothing will be done by resizing this half-height
* buffer to a full size frame.
*/
So, if I'm understanding this correctly, the routine isn't so much
de-interlacing the input, as it is throwing half of it away. Am I reading that
right? If so, is there a way to smooth the image using the IPIPE and preserve
full resolution?
Thanks!
Paul
