LBitmap::LambdaConnectedness

#include "ltwrappr.h"

virtual L_INT LBitmap::LambdaConnectedness(lambdaVal)

Performs image segmentation using a special region-growing algorithm called Lambda Connectedness.

Parameters

L_INT lambdaVal

Represents Lambda factor. Possible values are range from from 1 to 1000. The default value is 950.

Returns

Value Meaning
SUCCESS The function was successful.
< 1 An error occurred. Refer to Return Codes.

Comments

Lambda-connectedness is a technique used to find the connectivity between an image's pixels and then clusters them into groups.

Low values for lambda can result in one region.

High values for lambda can result in an over-segmented image.

This function supports 12- and 16-bit grayscale and 48- and 64-bit color images.

This function supports signed/unsigned images.
