Class FDiscGausConvolve

java.lang.Object

org.openimaj.image.processing.convolution.FDiscGausConvolve

All Implemented Interfaces:

ImageProcessor<FImage>, Processor<FImage>, SinglebandImageProcessor<Float,FImage>

public class FDiscGausConvolve
extends Object
implements SinglebandImageProcessor<Float,FImage>

From the matlab implementation of DISCGAUSSFFT which uses an FFT to apply a gaussian kernel. The matlab docs: % DISCGAUSSFFT(pic, sigma2) -- Convolves an image by the % (separable) discrete analogue of the Gaussian kernel by % performing the convolution in the Fourier domain. % The parameter SIGMA2 is the variance of the kernel. % Reference: Lindeberg "Scale-space theory in computer vision", Kluwer, 1994.

FDiscGausConvolve

public FDiscGausConvolve(float sigma2)

Construct with given variance

Parameters:

sigma2 - variance of the kernel

Method Detail

processImage

public void processImage(FImage image)

Description copied from interface: ImageProcessor

Process an image. Implementing classes must alter the image passed in-place or assign the output to the input using Image.internalAssign(Image).

Specified by:

processImage in interface ImageProcessor<FImage>

Parameters:

image - The image to process in place.
