Image deformation method and apparatus using deformation axis

摘要

The present invention relates to an image deformation method. An image deformation method using a deformation axis according to the present invention includes deforming the deformation axis based on deformation energy of points according to a deformation of at least one deformation axis including a plurality of points predetermined with respect to an image to be deformed; and deforming the image using a plurality of segments of the deformation axis divided based on points of the deformed deformation axis. According to the present invention, an image deformation method using a deformation axis is performed based on a freeform deformation axis (FDA) that is independent from a type of an original object and thus, may be more advantageous and may be utilized in combination with various types of deformation methods. Deformation of an image may be performed intuitively and in real time and thus, may be easily used by general users.
