Find 2D Contour at Specified Inner-Outer Level

Function

This Step sets the contours of a specified inner/outer layer in the mask image.

Usage Scenario

This Sep is a general 2D image contour extraction Step. It can be used between Steps “Orthographic Projection” and “Orthographic Projection Inverse” to obtain object contours in a 3D point cloud.

Input and Output

• Input: Mask input to this port will have contours of a specified inner/outer layer extracted.

• Output: Masks of contours of a specified inner/outer layer.
