import { optflow_createOptFlow_DeepFlow } from '@banou/opencv-wasm'

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

ARGUMENTSSee signature below
FUNCTIONoptflow_createOptFlow_DeepFlow
RETURN TYPEDenseOpticalFlow | null
Call structure. A void return can still write to destination arguments. The parameter descriptions define inputs, outputs and ownership.

DeepFlow optical flow algorithm implementation.

The class implements the DeepFlow optical flow algorithm described in [Weinzaepfel2013] . See also http://lear.inrialpes.fr/src/deepmatching/ . Parameters - class fields - that may be modified after creating a class instance:

  • member float alpha Smoothness assumption weight
  • member float delta Color constancy assumption weight
  • member float gamma Gradient constancy weight
  • member float sigma Gaussian smoothing parameter
  • member int minSize Minimal dimension of an image in the pyramid (next, smaller images in the pyramid are generated until one of the dimensions reaches this size)
  • member float downscaleFactor Scaling factor in the image pyramid (must be < 1)
  • member int fixedPointIterations How many iterations on each level of the pyramid
  • member int sorIterations Iterations of Succesive Over-Relaxation (solver)
  • member float omega Relaxation factor in SOR
optflow_createOptFlow_DeepFlow(): DenseOpticalFlow | null;
Returns

The DenseOpticalFlow | null result.
