Method for deforming smart graph-driven grid image

Abstract

The invention relates to a method for deforming a smart graph-driven grid image. In the method, global deformation parameters of the image are mapped to a two-dimensional grid to drive the grid to deform; the grid drives an embedded image of the grid to deform so as to solve the problems of non-accurate image deformations similar to cartoon animation deformations; and a user can quickly acquire an image deformation result through the interaction control of a control point on a smart graph. The method adopts a smart graph-based deformation driving template which has the characteristics of an embedded deformation rule and multi-component coordinative deformation, and can automatically generate appropriate grid driving parameters according to the global deformation parameters so as to generate a grid effect in real time. Besides, by performing cross regulation on different deformation weight coefficients, the method can control the deformation intensity. The method can acquire a two-dimensional grid deformation result of the embedded deformation rule at an interactive real-time speed, and can conveniently and quickly generate a deformation effect of a two-dimensional cartoon animation image by further solving the coordinate mapping and the gray mapping of an image pixel under grid driving.

Description

technical field [0001] The invention relates to digital image deformation technology, in particular to animation modeling creation technology for interactively deforming images depicting two-dimensional animation characters. Background technique [0002] In the current mainstream method of creating cartoon and animation characters, creators need to invest a lot of repetitive work to draw different facial expressions of the same animation characters. The use of deformation technology in computer graphics and image processing can provide a new solution for the expression drawing of animation characters. Applying deformation technology to the original animation shape to change it into an animation character shape with new facial expressions can greatly improve the creation efficiency of cartoon animation works and reduce a lot of repetitive drawing work for creators. For cartoon animation images saved in the form of images, using simple interactive methods to control their def...
