Abstract
Disclosed are various embodiments for determining a filter length according to a width and height of the reference block and selecting a filter based on the block size. Corresponding pixels from memory may be fetched based on the filter length and the block size. Reference pixels may be interpolated based on the selected filter to generate a prediction.
Claims20
A system, comprising:
- a decoded picture buffer;
- a pixel fetcher configured to:
- determine a filter size according to a width and a height of a reference block of a plurality of corresponding pixels from the decoded picture buffer;
- and
- fetch the corresponding pixels from the decoded picture buffer based on the filter length and the block size;
- and
- a multi-filter interpolator communicatively coupled to the fetcher, the multi-filter interpolator configured to:
- select a filter based on the block size or the filter type from the fetcher;
- and
- interpolate reference pixels based on the selected filter to generate a prediction.
