RDC6612U，Propose the inner contour when lifting the edge, what should I do?

The edge parameter is incorrect. The common edge mode has been selected

Adjust the edge threshold (increase, reduce internal recognition), set minimum contour filtering (area/length), perform binary or denoising on the image in advance, and manually delete internal contours if necessary

Ensure sufficient clearance between inner and outer contours, and set the distance between different contours correctly. If the gap is too small, it may cause both the inner and outer contours to be lifted together.
