Detailed Description

Class to apply an arbitrary series of affine transformations .

Affine operations apply transform pixel locations using affine matrix transformation. To optimize performance concatenated affine transformation's matrices are pre-multiplied.

Adapt Result Image

In some cases, it might make sense to automatically adapt the destinate image so that it contains the whole warping result image. Consider the following example

source image:
                                   +
A---------+                   +--/-----+
|         |                   |/       |
|         |    -------->     /|         |\
|    A    |     rot(45)     + |    A'   | +
|         |                  |         |/
|         |                   |\       /|
+---------+                   +-----/--+
                                   +

But obviously, the result image's corners are cut. If the "Adapt Result Image" option is set to true, the result image would be scaled to contain the whole rotated image and the affine matrix's shift is adpated in order to fit the result completely into the result image. If otherwise "Adpat Result Image is false, the result image's size will be identical to the source images size and the corners of the rotated image are cropped.

Please note: this options is by default set to "true". Only the TranslateOp will set it to false by default, because a pure translation is just compensated completely by the result image adaption.

Benchmarks:

example: a 300x400 rgb 8u-image was scaled by 1.001 and rotated by 1-360 degree in 3.6 degree steps We used a 2Ghz Core2Duo machine and g++ 4.3 with -O4 and -march=native flags set

With IPP: neares neighbour interpolation: 1ms linear interpolation 5ms

C++-Fallback: neares neighbour interpolation: 22ms linear interpolation 52ms
