Definitions
- the curve drawn by the user is used as an initial value, and the characteristic curve is defined as the following objective function:
- the input module is configured to receive a curve drawn along an edge of the feature on the image on which the feature curve is to be extracted. Specifically, the user manually draws a 3 ⁇ 4 line along the feature edge on the image using software developed by a library such as opener MFC. QT, which receives the curve drawn by the user.
- the calculation module is configured to calculate a harmonic vector field by using a curve drawn by the user as a boundary condition.
- the harmonic vector field is a spin-free vector field, that is, the rotation of the vector field is zero.
- the reserved short edge should be as long as possible; the reserved short edge record should be as consistent as possible with the harmonic vector field; the retained short edge curvature should be small; the reserved short edge should be close to the user's drawing Curve.
