Embodiment Construction

[0016] An embodiment of a method for designing a cyclic texture based on a texture sample map in the present invention will be described in detail below in conjunction with the accompanying drawings.

[0017] like figure 1 As shown, a circular texture design method based on texture samples includes four steps: input the texture samples; carry out end-to-end convolution on the texture samples in the horizontal direction, and use the graph cutting method to solve the optimal seam line to obtain the horizontal cyclic texture in the vertical direction; end-to-end rolling of the cyclic texture in the horizontal direction in the vertical direction, and use the graph cutting method to solve the optimal seam line to obtain the cyclic texture in the vertical direction; output the cyclic texture.

[0018] The four steps of this method are described in detail:

[0019] 1) Input texture sample

[0020] Input a texture sample image I with texture width w and height h, which can be an ima...

Abstract

The invention discloses a cycling texture design method based on texture master drawing; the method comprises the following steps: (1) inputting a texture master drawing, and folding the texture master drawing from head to tail in the horizontal direction; finding the best seam line through image cutting in the horizontally overlapped area so as to obtain the cycling texture in the horizontal direction; (2) folding the cycling texture in the horizontal direction from head to tail from the vertical direction, and finding the best seam line through image cutting in the vertically overlapped area so as to obtain the final cycling texture. The method of the invention is simple and convenient, which has low cost and precise control; the user can design the size of the cycling texture based on needs to achieve the purpose of designing cycling texture directly through texture master drawing.

Description

technical field [0001] The invention belongs to the field of computer image processing, can be applied to the fields of computer games, computer animation, computer graphics, virtual reality, digital media, etc., and in particular relates to a design method of a cyclic texture based on a texture sample map. Background technique [0002] Texture design has a wide range of application requirements in animation and game industries. Texture synthesis based on texture samples is a new texture synthesis technology developed rapidly in recent years. It synthesizes visually similar and continuous large textures based on given small area texture samples. Among existing non-parametric texture synthesis methods (cf.: Kwatra, V., , A., Essa, I., Turk, G., Bobick, A.: Graphcut textures: image and video synthesis using graph cuts. ACMTransactions on Graphics, 2003, 22(3), 277-286), often forcing the use of a Periodic boundary conditions, searching for candidate texture-like patches fro...
