backward mapping with various interpolations
Sink must be initialized with correct size and background color for invalid pixels. This way you can call it several times to create a panorama from several source images. For each pixel in sink, GetSourceCoordinates is called and the value in source interpolated.
- Parameters:
-
newSink,if true a new sink image is created that is large enough to hold the old sink and the new mapped src img. SuperSampling if > 1.0, intermediate image with isotropically enlarged width and height (by factor SuperSampling) is created and downsampled for the final image (most useful for nonlinear mappings)
- Returns:
- 0 on success, >0 means notification(such as 1 = not all pixels could be computed), -1 means failure
- Examples:
- ExampleCylinderMapping.cpp.
| int BIAS::BackwardMapping< unsigned char , unsigned char >::MapBi_ | ( | const Image< unsigned char > & | source, | |
| Image< unsigned char > & | sink, | |||
| InterpolationMethod | interpolationQuality | |||
| ) | [protected, inherited] |
bilinear, bicubc and nearest neighbor interpolation
| int BIAS::BackwardMapping< unsigned char , unsigned char >::MapTri_ | ( | Image< unsigned char > & | sink | ) | [protected, inherited] |
map image avoiding aliasing
This is almost correct regarding the sampling theorem, because it uses trilinear or anisotropic filtering over a pyramid. The local sampling frequency is estimated by analyzing the jacobian of the homography as a R^2->R^2 mapping. This is very slow. If possible, bicubic interpolation is done in the image, at borders (high pyramid levels) only bilinear.
In auto mode pyramid size is checked
| int BIAS::BackwardMapping< unsigned char , unsigned char >::MapTrilinearGreySimple_ | ( | Image< unsigned char > & | sink | ) | [protected, inherited] |
fast trilinear grey without special features
assumes one channel grey image, no alpha blending, no concatenation, no 2d offset (from auto image size) and no super sampling

| Image< unsigned char > & | sink, | |||
| InterpolationMethod | method, | |||
| bool | newSink = false | |||
| ) | [inherited] |
precomputes lookup coordinates for accessing src
If you want to apply the same mapping function over and over again, e.g. radial undistortion for a series of images, call this function once and MapWithLookupTable every time. sink must be of correct size !
- Returns:
- 0 on success, >0 means notification(such as 1 = not all pixels could be computed),
| void CylinderMapping::Reset | ( | ) |
if you want to call Map() twice for this object with different params, call Reset() before

Imagine that the source image is transformed with pcon into the intermediate image, which is then transformed by this into the sink
