ximgproc_fastGlobalSmootherFilter

Extended image processingfunctionOpenCV 5.0.0
import { ximgproc_fastGlobalSmootherFilter } from '@banou/opencv-wasm'

Use after await initOpenCV(). See the initialization and named imports guide.

ARGUMENTSguide, src, dst, lambda
FUNCTIONximgproc_fastGlobalSmootherFilter
RETURN TYPEvoid
Call structure. A void return can still write to destination arguments. The parameter descriptions define inputs, outputs and ownership.

Simple one-line Fast Global Smoother filter call. If you have multiple images to filter with the same guide then use FastGlobalSmootherFilter interface to avoid extra computations.

guide

image serving as guide for filtering. It should have 8-bit depth and either 1 or 3 channels.

src

source image for filtering with unsigned 8-bit or signed 16-bit or floating-point 32-bit depth and up to 4 channels.

dst

Output destination, filled by the native operation. destination image.

lambda

parameter defining the amount of regularization

sigma_color

parameter, that is similar to color space sigma in bilateralFilter.

lambda_attenuation

internal parameter, defining how much lambda decreases after each iteration. Normally, it should be 0.25. Setting it to 1.0 may lead to streaking artifacts.

num_iter

number of iterations used for filtering, 3 is usually enough.
