picture inter and intra prediction

Started by Sharan123 3 years ago2 replieslatest reply 3 years ago127 views

This question is regarding video coding standard MPEG/HEVC etc.

May I know on what basis a decision is made to encode a picture using intra or inter prediction method?

Thanks

Sharan-

I see that you're not getting any replies.  Googling inter vs. intra prediction brings up lots of hits.  One example I found explains what criteria H.264 uses, and advocates for computationally less complex methods:

This was in 2007, so no doubt for HEVC there are newer/better methods.

jbrower,

Thanks. I have seen multiple references. They explain pretty well how Intra and Inter prediction work in case of H.264 and H.265. However, I don't find description where it describes how an encoder decides to use one versus the other. I will continue to look at materials online.
