Function grab_cut

pub fn grab_cut(
    img: &impl ToInputArray,
    mask: &mut impl ToInputOutputArray,
    rect: Rect,
    bgd_model: &mut impl ToInputOutputArray,
    fgd_model: &mut impl ToInputOutputArray,
    iter_count: i32,
    mode: i32,
) -> Result<()>

Runs the GrabCut algorithm.

The function implements the GrabCut image segmentation algorithm.

Parameters

• img: Input 8-bit 3-channel image.
• mask: Input/output 8-bit single-channel mask. The mask is initialized by the function when mode is set to #GC_INIT_WITH_RECT. Its elements may have one of the #GrabCutClasses.
• rect: ROI containing a segmented object. The pixels outside of the ROI are marked as “obvious background”. The parameter is only used when mode==GC_INIT_WITH_RECT .
• bgdModel: Temporary array for the background model. Do not modify it while you are processing the same image.
• fgdModel: Temporary arrays for the foreground model. Do not modify it while you are processing the same image.
• iterCount: Number of iterations the algorithm should make before returning the result. Note that the result can be refined with further calls with mode==GC_INIT_WITH_MASK or mode==GC_EVAL .
• mode: Operation mode that could be one of the #GrabCutModes

C++ default parameters

• mode: GC_EVAL
