## Detailed Description

Encoder-side probabilities for pruning of various AV1 tools.

## Field Documentation

## ◆ obmc_probs

int FrameProbInfo::obmc_probs[FRAME_UPDATE_TYPES][BLOCK_SIZES_ALL]

obmc_probs[i][j] is the probability of OBMC being the best motion mode for jth block size and ith frame update type, averaged over past frames. If obmc_probs[i][j] < thresh, then OBMC search is pruned.

## ◆ warped_probs

int FrameProbInfo::warped_probs[FRAME_UPDATE_TYPES]

warped_probs[i] is the probability of warped motion being the best motion mode for ith frame update type, averaged over past frames. If warped_probs[i] < thresh, then warped motion search is pruned.

## ◆ tx_type_probs

int FrameProbInfo::tx_type_probs[FRAME_UPDATE_TYPES][TX_SIZES_ALL][TX_TYPES]

tx_type_probs[i][j][k] is the probability of kth tx_type being the best for jth transform size and ith frame update type, averaged over past frames. If tx_type_probs[i][j][k] < thresh, then transform search for that type is pruned.

## ◆ switchable_interp_probs

int FrameProbInfo::switchable_interp_probs[FRAME_UPDATE_TYPES][((SWITCHABLE_FILTERS+1) *4)][SWITCHABLE_FILTERS]

switchable_interp_probs[i][j][k] is the probability of kth interpolation filter being the best for jth filter context and ith frame update type, averaged over past frames. If switchable_interp_probs[i][j][k] < thresh, then interpolation filter search is pruned for that case.
