Constructor Detail

MergeRegionMeanShift

public MergeRegionMeanShift(int maxSpacialDistance,
                            float maxColorDistance)

Configures MergeRegionMeanShift

Parameters:

maxSpacialDistance - The maximum spacial distance (pixels) at which two modes can be for their regions to be merged together.

maxColorDistance - The maximum Euclidean distance two colors can be from each other for them to be merged.

Method Detail

process

public void process(boofcv.struct.image.GrayS32 pixelToRegion,
                    org.ddogleg.struct.GrowQueue_I32 regionMemberCount,
                    org.ddogleg.struct.FastQueue<float[]> regionColor,
                    org.ddogleg.struct.FastQueue<georegression.struct.point.Point2D_I32> modeLocation)

Merges together similar regions which are in close proximity to each other. After merging most of the input data structures are modified to take in account the changes.

Parameters:

pixelToRegion - (Input/output) Image that specifies the segmentation. Modified.

regionMemberCount - (Input/output) Number of pixels in each region. Modified.

regionColor - (Input/output) Color of each region. Modified.

modeLocation - (Input) Location of each region's mode. Not modified.

markMergeRegions

protected void markMergeRegions(org.ddogleg.struct.FastQueue<float[]> regionColor,
                                org.ddogleg.struct.FastQueue<georegression.struct.point.Point2D_I32> modeLocation,
                                boofcv.struct.image.GrayS32 pixelToRegion)

Takes the mode of a region and searches the local area around it for other regions. If the region's mode is also within the local area its color is checked to see if it's similar enough. If the color is similar enough then the two regions are marked for merger.
