clip interpolated value to outputstoragetype and merge old and new value according to alpha

This function must be inplemented for diferent template types rather than for derived classes, e.g. if bicubic interpolation estimates the grey value 257.8 for an unsinged char image, this is rounded and clipped here to 255.0 since this is the maximum allowed uchar.

inherited

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

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
