Package in.itzmeanjan.filterit.segmentation

Class RegionGrowing

java.lang.Object

in.itzmeanjan.filterit.segmentation.RegionGrowing

public class RegionGrowing
extends java.lang.Object

Given a buffered image ( grayscale, if not gray scaled yet, to be done inside this implementation ), it'll compute segmented image using a seed pixel location, applying region growing algorithm

This implementation doesn't have in-built concurrency support yet

Method Detail

segment

public java.awt.image.BufferedImage segment(java.awt.image.BufferedImage img,
                                            int x,
                                            int y,
                                            int relaxation)

Computes segmented image following this rule, while considering specified pixel location as seed pixel

all pixel locations having intensity within [intensity - relaxation, intensity + relaxation] to be kept ( as they are ) & remaining to be made black ( black used as background color )

! For segmenting N objects requires N-run, which is not really a good thing !

Parameters:

img - Image to be segmented

x - X-coordinate of Pixel, from which segmentation to be started

y - Y-coordinate of Pixel, from which segmentation to be started

relaxation - relaxation around initial pixel's intensity value

Returns:

Segmented image

segment

public java.awt.image.BufferedImage segment(java.lang.String img,
                                            int x,
                                            int y,
                                            int relaxation)

Segments image while considering specified pixel location as seed pixel

Selection of seed pixel is very important for good segmentation result

Parameters:

img - Image to be segmented

x - X-coordinate of Pixel, from which segmentation to be started

y - Y-coordinate of Pixel, from which segmentation to be started

relaxation - relaxation around initial pixel's intensity value

Returns:

Segmented image
