AdaptivePercentile

Performs Percentile filtering steered by paramter images

SYNOPSIS

#include "dip_adaptive.h"

dip_Error DIP_TPI_FUNC(dip_AdaptivePercentile)( in, out, para_images, filterSize, precentile )

DATA TYPES

sfloat

FUNCTION

This function performs percentile filtering steerd by the information stored in the paramter images (local orientation). The meaning of the parameter images depends on the dimensionality of the input image. Up to now only 2 and 3D images are supported for adaptive filtering. If the input image is not of type float it is converted to that type.

para_images: ImageArray containing orientation images.

2D: angle of the orientation.

3D: polar coordinate phi, theta for intrinsic 1D structures polar coordinates of two orientations for intrinsic 2D structures.
