12.8.4 Warp adjustment principle
Description
Warping adjustment enables the
relocation of pixel groups
in an image in order to introduce spacial distortion. To make the
procedure comprehensible, there are some rules and features.
The use of warping adjustment leads to image quality loss! The more geometry adjustment is applied, the
more quality loss.
Moving an anchor point causes pixels in the same region to be moved gradually with this one pixel, depending on their distance to
it. The size of the region of impact depends on the anchor point: some anchor pixels have impact on the full image, while others
have impact on a small area only. The full image is divided in
33 x 33 regions
. The smallest region of impact is one of these 1089
regions.

33 x 33 regions in an image
Warp adjustment is divided in
six modes
:
•
2 x 2 (highest mode);
•
3 x 3;
•
5 x 5;
•
9 x 9;
•
17 x 17;
•
33 x 33 (lowest mode).
The six modes represent
21 levels
, each level representing its own group of
anchor points
.

Level hierarchy
The
hierarchy
of these levels is very important: each level interacts with all lower levels. Adjusting a point on a certain level affects
the points in all or some of the lower levels. The impact depends on the level itself. Therefore it is important to adjust the geometry
starting from level one and going down to lower levels as required. In practice it will not be needed to adjust the anchor points of
levels 7 and lower.
