FUNCTIONximgproc_createScanSegment

RETURN TYPEximgproc_ScanSegment | null

Call structure. A void return can still write to destination arguments. The parameter descriptions define inputs, outputs and ownership.

Initializes a ScanSegment object.

The function initializes a ScanSegment object for the input image. It stores the parameters of the image: image_width and image_height. It also sets the parameters of the F-DBSCAN superpixel algorithm, which are: num_superpixels, threads, and merge_small.

ximgproc_createScanSegment(image_width: number, image_height: number, num_superpixels: number, slices: number, merge_small: boolean): ximgproc_ScanSegment | null;

3 available overloads

ximgproc_createScanSegment(image_width: number, image_height: number, num_superpixels: number): ximgproc_ScanSegment | null;

ximgproc_createScanSegment(image_width: number, image_height: number, num_superpixels: number, slices: number): ximgproc_ScanSegment | null;

ximgproc_createScanSegment(image_width: number, image_height: number, num_superpixels: number, slices: number, merge_small: boolean): ximgproc_ScanSegment | null;

image_width: Image width.
image_height: Image height.
num_superpixels: Desired number of superpixels. Note that the actual number may be smaller due to restrictions (depending on the image size). Use getNumberOfSuperpixels() to get the actual number.
slices: Number of processing threads for parallelisation. Setting -1 uses the maximum number of threads. In practice, four threads is enough for smaller images and eight threads for larger ones.
merge_small: merge small segments to give the desired number of superpixels. Processing is much faster without merging, but many small segments will be left in the image.

Returns

The ximgproc_ScanSegment | null result.
