All Implemented Interfaces:

BilateralF, ProgressReporter

public class BilateralFilterScalar
extends GenericFilterScalar
implements BilateralF

Scalar (non-separable) version of the Bilateral filter as proposed in [1]. On color images, this filter is applied separately to each color component. The filter uses Gaussian domain and range kernels and can be applied to all image types. See Sec. 17.2 of [2] for additional details.

Method Details

doPixel

protected float doPixel(PixelPack.PixelSlice plane,
 int u,
 int v)

Description copied from class: GenericFilterScalar

This method defines the steps to be performed for a single image pixel and must be implemented by any concrete sub-class. The source data are passed as a PixelPack.PixelSlice container, which holds the scalar values of one image component. The method PixelPack.PixelSlice.getVal(int, int) should be used to read individual pixel values. These data should not be modified but the (float) result of the single-pixel calculation must be returned.

Specified by:

doPixel in class GenericFilterScalar

Parameters:

plane - the scalar-valued data for a single image component

u - the current x-position

v - the current y-position

Returns:

the result of the filter calculation for this pixel
