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

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

ARGUMENTSimg1, keylines1, img2, keylines2
FUNCTIONline_descriptor_drawLineMatches
RETURN TYPEvoid
Call structure. A void return can still write to destination arguments. The parameter descriptions define inputs, outputs and ownership.

Draws the found matches of keylines from two images.

Note: If both matchColor and singleLineColor are set to their default values, function draws matched lines and line connecting them with same color
