Assembly

OpenCvSharp.dll

ConnectedComponentsWithStats(InputArray, OutputArray, OutputArray, OutputArray, PixelConnectivity)

computes the connected components labeled image of boolean image. image with 4 or 8 way connectivity - returns N, the total number of labels [0, N-1] where 0 represents the background label. ltype specifies the output label image type, an important consideration based on the total number of labels or alternatively the total number of pixels in the source image.

public static int ConnectedComponentsWithStats(InputArray image, OutputArray labels, OutputArray stats, OutputArray centroids, PixelConnectivity connectivity = PixelConnectivity.Connectivity8)

Parameters

image InputArray

the image to be labeled

labels OutputArray

destination labeled image

stats OutputArray

statistics output for each label, including the background label, see below for available statistics. Statistics are accessed via stats(label, COLUMN) where COLUMN is one of cv::ConnectedComponentsTypes

centroids OutputArray

floating point centroid (x,y) output for each label, including the background label

connectivity PixelConnectivity

8 or 4 for 8-way or 4-way connectivity respectively

Returns

int

ConnectedComponentsWithStats(InputArray, OutputArray, OutputArray, OutputArray, PixelConnectivity, MatType)

computes the connected components labeled image of boolean image. image with 4 or 8 way connectivity - returns N, the total number of labels [0, N-1] where 0 represents the background label. ltype specifies the output label image type, an important consideration based on the total number of labels or alternatively the total number of pixels in the source image.
