Signature

Description

interpolate_scattered_data_points_to_imageinterpolate_scattered_data_points_to_imageInterpolateScatteredDataPointsToImageInterpolateScatteredDataPointsToImageInterpolateScatteredDataPointsToImage interpolates the data points, given in RowsRowsRowsRowsrows and ColumnsColumnsColumnsColumnscolumns with the corresponding measurement ValuesValuesValuesValuesvalues, and returns the result in ImageInterpolatedImageInterpolatedImageInterpolatedImageInterpolatedimageInterpolated. The size of the output image is defined by its WidthWidthWidthWidthwidth and its HeightHeightHeightHeightheight with the upper left corner at (0,0). In order to interpolate at negative coordinates of (RowsRowsRowsRowsrows,ColumnsColumnsColumnsColumnscolumns), simply translate all input points accordingly. With the parameter MethodMethodMethodMethodmethod the interpolation algorithm is specified. So far, only the 'thin_plate_splines'"thin_plate_splines""thin_plate_splines""thin_plate_splines""thin_plate_splines" are supported. This method interpolates on a global scale, which means that all points are regarded for the interpolation, no matter how far away they are. The influence of far points is correlated to where r defines the distance of two points. In comparison to interpolate_scattered_data_imageinterpolate_scattered_data_imageInterpolateScatteredDataImageInterpolateScatteredDataImageInterpolateScatteredDataImage, interpolate_scattered_data_points_to_imageinterpolate_scattered_data_points_to_imageInterpolateScatteredDataPointsToImageInterpolateScatteredDataPointsToImageInterpolateScatteredDataPointsToImage also supports subpixel coordinates for RowsRowsRowsRowsrows and ColumnsColumnsColumnsColumnscolumns. If the same data points (RowsRowsRowsRowsrows,ColumnsColumnsColumnsColumnscolumns,ValuesValuesValuesValuesvalues) are used for the interpolation of different output images in subsequent steps, the operator create_scattered_data_interpolatorcreate_scattered_data_interpolatorCreateScatteredDataInterpolatorCreateScatteredDataInterpolatorCreateScatteredDataInterpolator may be more efficient.

The following parameters can be adjusted with GenParamNameGenParamNameGenParamNameGenParamNamegenParamName and GenParamValueGenParamValueGenParamValueGenParamValuegenParamValue:

'alpha'"alpha""alpha""alpha""alpha":

The parameter 'alpha'"alpha""alpha""alpha""alpha" is a smoothing factor. For 'alpha'"alpha""alpha""alpha""alpha" = 0, all points passed in (RowsRowsRowsRowsrows,ColumnsColumnsColumnsColumnscolumns,ValuesValuesValuesValuesvalues) are interpolated exactly. With 'alpha'"alpha""alpha""alpha""alpha" getting larger, the interpolation smoothes the points in way that all interpolated points of the result image ImageInterpolatedImageInterpolatedImageInterpolatedImageInterpolatedimageInterpolated lie on a common plane. Default value is 0. Restrictions: 'alpha'"alpha""alpha""alpha""alpha" >= 0

Execution Information

• Multithreading type: reentrant (runs in parallel with non-exclusive operators).
• Multithreading scope: global (may be called from any thread).
• Processed without parallelization.

Parameters

Result

If the parameters are valid, the operator interpolate_scattered_data_points_to_imageinterpolate_scattered_data_points_to_imageInterpolateScatteredDataPointsToImageInterpolateScatteredDataPointsToImageInterpolateScatteredDataPointsToImage returns the value 2 (H_MSG_TRUE). If necessary, an exception is raised.
