[x264-devel] Re: Regarding quarter pixel ME

[mahesh k]

I went through the JM reference code but I was not able to understand it.
Recently i implemented quarter pixel motion estimation. First I interpolated
the whole reference frame upto quarter pixel level and stored this in a
buffer. Then  I found the integer pixel motion vector using the previos
frame as reference frame (non interpolated reference frame) and the search
criterion i used was SAD. Then I performed the sub pixel refinement using
the best integer pixel motion vector coordinates as center using the
quarterly interpolated frame as reference.

U plz tell me whether this was correct or not.

Regards,
Mahesh.
