Block searching procedure for motion estimation

A method of graphics processing, comprising:

• obtaining a first frame and a second frame of a plurality of frames in a scene, wherein the second frame is subsequent to the first frame in the plurality of frames;
• calculating a set of first motion vectors in the first frame and a set of second motion vectors in the second frame, wherein the set of first motion vectors and the set of second motion vectors are calculated based on a block matching procedure for a set of first blocks in the first frame and a set of second blocks in the second frame, wherein each of the set of first blocks includes a plurality of first pixels and each of the set of second blocks includes a plurality of second pixels, wherein the block matching procedure is associated with comparing at least one first block of the set of first blocks to at least one second block of the set of second blocks;
• and
• estimating at least one third frame in the plurality of frames based on the set of first motion vectors in the first frame and the set of second motion vectors in the second frame, wherein the at least one third frame is subsequent to the second frame in the plurality of frames.

An apparatus for graphics processing, comprising:

• means for obtaining a first frame and a second frame of a plurality of frames in a scene, wherein the second frame is subsequent to the first frame in the plurality of frames;
• means for calculating a set of first motion vectors in the first frame and a set of second motion vectors in the second frame, wherein the set of first motion vectors and the set of second motion vectors are calculated based on a block matching procedure for a set of first blocks in the first frame and a set of second blocks in the second frame, wherein each of the set of first blocks includes a plurality of first pixels and each of the set of second blocks includes a plurality of second pixels, wherein the block matching procedure is associated with comparing at least one first block of the set of first blocks to at least one second block of the set of second blocks;
• and
• means for estimating at least one third frame in the plurality of frames based on the set of first motion vectors in the first frame and the set of second motion vectors in the second frame, wherein the at least one third frame is subsequent to the second frame in the plurality of frames.

A computer-readable medium storing computer executable code for graphics processing, the code when executed by a processor causes the processor to:

• calculate a set of first motion vectors in the first frame and a set of second motion vectors in the second frame, wherein the set of first motion vectors and the set of second motion vectors are calculated based on a block matching procedure for a set of first blocks in the first frame and a set of second blocks in the second frame, wherein each of the set of first blocks includes a plurality of first pixels and each of the set of second blocks includes a plurality of second pixels, wherein the block matching procedure is associated with comparing at least one first block of the set of first blocks to at least one second block of the set of second blocks;
• and
• estimate at least one third frame in the plurality of frames based on the set of first motion vectors in the first frame and the set of second motion vectors in the second frame, wherein the at least one third frame is subsequent to the second frame in the plurality of frames.
