Adaptive interpolation filter for motion compensated prediction
Standardized hybrid video coding systems are based on motion compensated prediction with fractional-pel displacement vector resolution. In the recent JVT video coding scheme (MPEG-4 part 10, H.264) displacement vector resolutions of 1/4or 1/8-pel are applied. In order to estimate and compensate these fractional-pel displacements, interpolation filters are used. So far, these interpolation filte...
متن کاملAdaptive Interpolation Filter for Motion and . . .
Common motion compensated hybrid video coding standards such as H.263, MPEG-1, MPEG-2, MPEG-4 are based on a fractional-pel displacement vector (DV) resolution of 1/2-pel. Recent approaches like MPEG-4 (ACE-profile) and H.26L use higher DV resolutions of 1/4-pel and 1/8-pel. In order to estimate and compensate fractional-pel displacements, the image signal has to be interpolated. Especially for...
متن کاملAdaptive pre-interpolation filter for high efficiency video coding
The proposed interpolation filter comprises two concatenating filters, adaptive pre-interpolation filter (APIF) and the normative interpolation filter in H.264/AVC. The former is applied only to the integer pixels in the reference frames; the latter generates all the sub-position samples, supported by the output of APIF. The convolution of APIF and the standard filter minimizes the motion predi...
متن کاملAdaptive Interpolation Filter for Motion Compensated Hybrid Video Coding
Common hybrid video coding standards such as H.263, MPEG-1,2,4 are based on motion compensated prediction. For the motion compensated prediction purpose, displacement vectors with fractional-pel resolutions (e.g. 1/2-pel or 1/4-pel) are used. In order to estimate and compensate fractional-pel displacements, the image signal has to be interpolated. The most popular and very simple interpolation ...
