Class SobelEdgeDetector

java.lang.Object

Catalano.Imaging.Filters.SobelEdgeDetector

All Implemented Interfaces:

IApplyInPlace

public class SobelEdgeDetector
extends java.lang.Object
implements IApplyInPlace

Sobel edge detector. The filter searches for objects' edges by applying Sobel operator. Each pixel of the result image is calculated as approximated absolute gradient magnitude for corresponding pixel of the source image: |G| = |Gx| + |Gy] , where Gx and Gy are calculate utilizing Sobel convolution kernels. Using the above kernel the approximated magnitude for pixel x is calculate using the next equation: |G| = |P1 + 2P2 + P3 - P7 - 2P6 - P5| + |P3 + 2P4 + P5 - P1 - 2P8 - P7|

Returns:

Scale intensity value.

setScaleIntensity

public void setScaleIntensity(boolean scaleIntensity)

Set scale intensity. Check if edges' pixels intensities of the result image should be scaled in the range of the lowest and the highest possible intensity values.

Parameters:

scaleIntensity - Scale intensity value.

applyInPlace

Specified by:

applyInPlace in interface IApplyInPlace

Parameters:

fastBitmap - Image to be processed.
