  • the exemplary methods and apparatuses can be applied to predict motion vectors and enhancements in the design of a B picture Direct Mode.
  • Such methods and apparatuses are particularly suitable for multiple picture reference codecs, such as, for example, JVT, and can achieve considerable coding gains especially for panning sequences or scene changes.
  • Bidirectionally Predictive (B) pictures are an important part of most video coding standards and systems since they tend to increase the coding efficiency of such systems, for example, when compared to only using Predictive (P) pictures.
  • This improvement in coding efficiency is mainly achieved by the consideration of bidirectional motion compensation, which can effectively improve motion compensated prediction and thus allow the encoding of significantly reduced residue information.
  • the introduction of the Direct Prediction mode for a Macroblock/block within such pictures can further increase efficiency considerably (e.g., more than 10-20%) since no motion information is encoded. Such may be accomplished, for example, by allowing the prediction of both forward and backward motion information to be derived directly from the motion vectors used in the corresponding macroblock of a subsequent reference picture.
  • FIG. 4 illustrates Direct Prediction in B picture at time coding based on P frames at times t and t+2, and the applicable motion vectors (MVs).

  • FIG. 5 illustrates what happens when a scene change occurs in the video sequence and/or what happens when the collocated block is intra.
  • bidirectional prediction would provide little if any benefit.
  • the Direct Mode could be completely wasted.
  • conventional implementations of the Direct Mode restrict it to always perform a bidirectional prediction of a Macroblock.
  • FIG. 7 is an illustrative diagram depicting how Direct Mode is handled when the reference picture of the collocated block in the subsequent P picture is other than zero, in accordance with certain implementations of the present invention.
  • a new Direct Macroblock type is introduced wherein both temporal prediction and/or spatial prediction is considered.
  • the type(s) of prediction used can depend on the type of reference picture information of the first subsequent P reference picture, for example.
  • Direct Mode is designed as a bidirectional prediction scheme where motion parameters are always predicted in a temporal way from the motion parameters in the subsequent P images.
  • an enhanced Direct Mode technique is provided in which spatial information may also/alternatively be considered for such predictions.
  • One or more of the following exemplary techniques may be implemented as needed, for example, depending on the complexity and/or specifications of the system.
  • One technique is to implement spatial prediction of the motion vector parameters of the Direct Mode without considering temporal prediction.
  • Spatial prediction can be accomplished, for example, using existing Motion Vector prediction techniques used for motion vector encoding (such as, e.g., median prediction). If multiple picture references are used, then the reference picture of the adjacent blocks may also be considered (even though there is no such restriction and the same reference, e.g. 0, could always be used).
  • Motion parameters and reference pictures could be predicted as follows and with reference to FIG. 3, which illustrates spatial predication associated with portions A-E (e.g., macroblocks, slices, etc.) assumed to be available and part of a picture.
  • E is predicted in general from A, B, C as Median (A, B, C). If C is actually outside of the picture then D is used instead. If B, C, and D are outside of picture, then only A is used, where as if A does not exist, such is replaced with (0,0).
  • FIG. 3 illustrates spatial predication associated with portions A-E (e.g., macroblocks, slices, etc.) assumed to be available and part of a picture.
  • E is predicted in general from A, B, C as Median (A, B, C). If C is actually outside of the picture then D is used instead. If B, C, and D are outside of picture, then only A is used, where as if A does not exist, such is replaced with (0,0).
  • Those skilled in the art will recognize that spatial prediction
  • One method may be to select a minimum reference picture among the predictions.
  • a median reference picture may be selected.
  • a selection may be made between a minimum reference picture and median reference picture, e.g., if the minimum is zero.
  • a higher priority could also be given to either vertical or horizontal predictors (A and B) due to their possibly stronger correlation with E.
  • Temporal prediction is used for Macroblocks if the subsequent P reference is non intra as in existing codecs. Attention is now drawn to FIG. 8, in which MV FW and MV BW are derived from spatial prediction (Median MV of surrounding Macroblocks). If either one is not available (i.e., no predictors) then one-direction is used. If a subsequent P reference is intra, then spatial prediction can be used instead as described above. Assuming that no restrictions exist, if one of the predictions is not available then Direct Mode becomes a single direction prediction mode.
  • temporal prediction will not be as efficient in the direct mode for blocks when the collocated P reference block has a non-zero reference picture.
  • spatial prediction may also be used as above.
  • one may estimate scaling parameters if one of the surrounding macroblocks also uses the same reference picture as the collocated P reference block.
  • special handling may be provided for the case of zero motion (or close to zero motion) with a non-zero reference.
  • regardless of temporal distance forward and backward motion vectors could always be taken as zero.
  • the best solution may be to always examine the reference picture information of surrounding macroblocks and based thereon decide on how the direct mode should be handled in such a case.
  • Case B If all surrounding macroblocks use different reference pictures than the collocated P reference, then spatial prediction appears to be a better choice and temporal prediction is not used.
  • Case D Spatial or temporal prediction of Direct Mode macroblocks could be signaled inside the image header. A pre-analysis of the image could be performed to decide which should be used.
  • Case E Correction of the temporally predicted parameters based on spatial information (or vice versa).
  • spatial information could be a very good candidate for the direct mode prediction.
  • a correction could also be done on the phase, thus correcting the sub pixel accuracy of the prediction.
  • FIG. 10 illustrates a joint spatio-temporal prediction for Direct Mode in B picture coding.
  • Direct Mode can be a 1- to 4-direction mode depending on information available.
  • Bi-directional prediction for Direct Mode macroblocks a multi-hypothesis extension of such mode can be done and multiple predictions used instead.
  • Direct Mode macroblocks can be predicted using from one up to four possible motion vectors depending on the information available. Such can be decided, for example, based on the mode of the collocated P reference image macroblock and on the surrounding macroblocks in the current B picture. In such a case, if the spatial prediction is too different than the temporal one, one of them could be selected as the only prediction in favor of the other. Since spatial prediction as described previously, might favor a different reference picture than the temporal one, the same macroblock might be predicted from more than 2 reference pictures.
  • the JVT standard does not restrict the first future reference to be a P picture.
  • a picture can be a B as illustrated in FIG. 12, or even a Multi-Hypothesis (MH) picture.
  • MH Multi-Hypothesis
  • the first subsequent reference picture is a B picture (pictures B 8 and B 9 ). This enables one to use more candidates for Direct Mode prediction especially if bidirectional prediction is used within the B picture.
  • the collocated reference block in the first future reference is using bidirectional prediction
  • the corresponding motion vectors forward or backward
  • the corresponding motion vectors are used for calculating the motion vectors of the current block. Since the backward motion vector of the reference corresponds to a future reference picture, special care should be taken in the estimate of the current motion parameters. Attention is drawn, for example to FIG. 12 in which the first subsequent reference picture is a B picture (pictures B 8 and B 9 ). This enables one to use more candidates for Direct Mode prediction especially if bidirectional prediction is used within the B picture.
  • the backward motion vector of B 8 ⁇ right arrow over (MV) ⁇ B8bw can be calculated as 2 ⁇ right arrow over (MV) ⁇ B7bw due to the temporal distance between B 8 , B 7 and P 6
  • the backward motion vector can be taken as ⁇ right arrow over (MV) ⁇ B7bw , if though these refer to the B 7 .
  • a similar conclusion can be deduced about the forward motion vectors. Multiple picture reference or intra macroblocks can be handled similar to the previous discussion.
  • bidirectional prediction for the collocated block If bidirectional prediction for the collocated block is used, then, in this example, one may estimate four possible predictions for one macroblock for the direct mode case by projecting and inverting the backward and forward motion vectors of the reference.
  • Motion vector prediction for multi-picture reference motion compensation can significantly affect the performance of both B and P picture coding.
  • Existing standards such as, for example, JVT, do not always consider the reference pictures of the macroblocks used in the prediction. The only consideration such standards do make is when only one of the prediction macroblocks uses the same reference. In such a case, only that predictor is used for the motion prediction. There is no consideration of the reference picture if only one or all predictors are using a different reference.
  • FIG. 11 illustrates Motion Vector prediction of a current block (C) considering the reference picture information of predictor macroblocks (Pr) and performance of proper adjustments (e.g., scaling of the predictors).
  • MV ⁇ pred TR ⁇ Median ⁇ ( MV ⁇ A TR A , MV ⁇ B TR B , MV ⁇ C TR C )
  • Motion Vector prediction as discussed previously is basically median biased, meaning that the median value among a set of predictors is selected for the prediction. If one only uses one type of macroblock (e.g., 16 ⁇ 16) with one Motion Vector (MV), then these predictors can be defined, for example, as illustrated in FIG. 15. Here, MV predictors are shown for one MV. In FIG. 15 a , the MB is not in the first row or the last column. In FIG. 15 b , the MB is in the last column. In FIG. 15 c , the MB is in the first row.
  • macroblock e.g. 16 ⁇ 16
  • MV predictors are shown for one MV.
  • FIG. 15 a the MB is not in the first row or the last column.
  • the MB is in the last column.
  • FIG. 15 c the MB is in the first row.
  • the JVT standard improves on this further by also considering the case that only one of the three predictors exists (i.e. Macroblocks are intra or are using a different reference picture in the case of multi-picture prediction). In such a case, only the existing or same reference predictor is used for the prediction and all others are not examined.
  • Intra coding does not always imply that a new object has appeared or that scene changes. It might instead, for example, be the case that motion estimation and compensation is inadequate to represent the current object (e.g., search range, motion estimation algorithm used, quantization of residue, etc) and that better results could be achieved through Intra Coding instead. The available motion predictors could still be adequate enough to provide a good motion vector predictor solution.
  • MPEG-4 and H.263 standards can have up to four such subblocks (e.g., with size 8 ⁇ 8 ), where as the JVT standard allows up to sixteen subblocks while also being able to handle variable block sizes (e.g., 4 ⁇ 4, 4 ⁇ 8, 8 ⁇ 4,8 ⁇ 8, 8 ⁇ 16, 16 ⁇ 8, and 16 ⁇ 16).
  • JVT also allows for 8 ⁇ 8 Intra subblocks, thus complicating things even further.
  • FIGS. 16 a - c having a similar arrangement to FIGS. 15 a - c , respectively.
  • Motion Vector predictors are shown for one MV with 8 ⁇ 8 partitions. Even though the described predictors could give reasonable results in some cases, it appears that they may not adequately cover all possible predictions.
  • FIGS. 17 a - c Attention is drawn next to FIGS. 17 a - c , which are also in a similar arrangement to FIGS. 15 a - c , respectively.
  • FIGS. 17 a - c there are two additional predictors that could also be considered in the prediction phase (C 1 and A 2 ). If 4 ⁇ 4 blocks are also considered, this increases the possible predictors by four.
  • predictors A 1 , and C 2 are essentially too close with one another and it may be the case that they may not be too representative in the prediction phase. Instead, selecting predictors A 1 , C 1 , and B seems to be a more reliable solution due to their separation.
  • An alternative could also be the selection of A 2 instead of A 1 but that may again be too close to predictor B. Simulations suggest that the first case is usually a better choice.
  • a 2 could be used instead of A l .
  • For the first row either one of A 1 and A 2 or even their average value could be used. Gain up to 1% was noted within JVT with this implementation.
  • ⁇ right arrow over (MV) ⁇ pred Median( Ave ( ⁇ right arrow over (MV) ⁇ C 1 , ⁇ right arrow over (MV) ⁇ C 2 ), Ave ( ⁇ right arrow over (MV) ⁇ A 1 , ⁇ right arrow over (MV) ⁇ A 2 ), ⁇ right arrow over (MV) ⁇ B ).
  • the median can be calculated as:
  • ⁇ right arrow over (MV) ⁇ pred (Median(Median( ⁇ right arrow over (MV) ⁇ C 1 , ⁇ right arrow over (MV) ⁇ C 2 , ⁇ right arrow over (MV) ⁇ D ), . . . Median( ⁇ right arrow over (MV) ⁇ D , ⁇ right arrow over (MV) ⁇ A 1 , ⁇ right arrow over (MV) ⁇ C 2 ),Median( ⁇ right arrow over (MV) ⁇ B , ⁇ right arrow over (MV) ⁇ A 1 , ⁇ right arrow over (MV) ⁇ A 2 )))
  • ⁇ right arrow over (MV) ⁇ pred Median( ⁇ right arrow over (MV) ⁇ C 1 , ⁇ right arrow over (MV) ⁇ C 2 , ⁇ right arrow over (MV) ⁇ D , ⁇ right arrow over (MV) ⁇ B , ⁇ right arrow over (MV) ⁇ A 1 , ⁇ right arrow over (MV) ⁇ A 2 )
  • JVT allows the existence of Intra subblocks within an Inter Macroblock (e.g., tree macroblock structure), such could also be taken in consideration within the Motion Prediction.
  • a subblock e.g., from Macroblocks above or left only
  • the adjacent subblock may be used instead.
  • Al is intra but A 2 is not
  • Al can be replaced by A 2 in the prediction.
  • a further possibility is to replace one missing Intra Macroblock with the MV predictor from the upper-left position. In FIG. 17 a , for example, if C 1 is missing then D may be used instead.
