Image processing system and program

A computer-readable medium comprising an image processing program readable by a computer operably connected to a storage device storing original form data including the data of a triangle mesh constructing an object to be deformed, the program causing the computer to perform:

• a first mesh creating step of loading the original form data from the storage device based on the information describing multiple handle positions including a fixed point and a movable point on the triangle mesh on the image from the input device, creating intermediate mesh data including data of an intermediate triangle mesh that provides a minimum of the quadratic error metric expressing the difference between the original triangle mesh and the processed intermediate triangle mesh under a state allowing the rotation and expansion/contract of the original triangle mesh described by the original form data, and storing the intermediate mesh data in the storage device;
• and
• a second mesh creating step of creating final mesh data including data of a final triangle mesh that provides the minimum of a error metric expressing the difference between the intermediate triangle mesh and the final triangle mesh under a state allowing the rotation and parallel movement of the intermediate triangle mesh described by the intermediate mesh data and not allowing uneven distortion, expansion/contraction and scale-up/down, and storing the final mesh data in the storage device.

A method of image processing, comprising the steps of:

• (a) providing a storage device for original form data including data of a triangle mesh constructing an object to be deformed;
• (b) loading the original form data from the storage device based on information describing multiple handle positions including a fixed point and a movable point on the triangle mesh on the image from the input device;
• (c) creating intermediate mesh data including data of an intermediate triangle mesh that provides the minimum of a quadratic error metric expressing a difference between the original triangle mesh and the processed intermediate triangle mesh under a state allowing the rotation and expansion/contract of the original triangle mesh described by the original form data;
• (d) storing the intermediate mesh data in the storage device;
• (e) creating final mesh data including data of a final triangle mesh that provides a minimum of an error metric expressing a difference between the intermediate triangle mesh and the final triangle mesh under a state allowing the rotation and parallel movement of the intermediate triangle mesh described by the intermediate mesh data and not allowing uneven distortion, expansion/contraction and scale-up/down;
• and
• (f) storing the final mesh data in the storage device.
