Diamond type & size for motion estimation.
|

|
Motion search is an iterative process.
|
||||||
|
Using a small diamond does not limit the search to finding only small
|
||||||
|
motion vectors.
|
||||||
|
It is just somewhat more likely to stop before finding the very best motion
|
||||||
|
vector, especially when noise is involved.
|
||||||
|
Bigger diamonds allow a wider search for the best motion vector, thus are
|
||||||
|
slower but result in better quality.

Big normal diamonds are better quality than shape-adaptive diamonds.

|
||||||
|
Shape-adaptive diamonds are a good tradeoff between speed and quality.
