METHOD AND SYSTEM FOR EXTRACTING IMAGE CHARACTERISTIC CURVE |
摘要 |
Provided is a method for extracting an image characteristic curve. The method comprises the following steps: drawing an approximate curve along a characteristic edge of an image from which a characteristic curve is to be extracted; obtaining short edges in the image; calculating a harmonic vector field by using the drawn curve as a boundary condition; filtering the short edges in the image by using the harmonic vector field; updating the vector field by using the short edges left in the image as boundary conditions; and obtaining an optimal characteristic curve of the image by using the energy of a minimized spline curve in the vector field. Also provided is a system for extracting an image characteristic curve. The image characteristic curve can ensure the smoothness and a bending characteristic. |
