Bas‐relief layout arrangement via automatic method optimization

Abstract

It is significant to achieve automatic arrangement for bas-relief layout which can be noticeably more efficient than the time-consuming manual process. In fact, nearly none work has been reported in terms of bas-relief layout arrangement. In this paper, we propose a novel approach to tackle this problem. Specifically, we first identify the evaluation indicators to account for different aesthetic factors, and model the goodness of each indicator. We then cast the bas-relief layout as a combinatorial optimization problem based on those evaluation indicators and a geometric mean model. The contribution of this paper is to propose an objective function for bas-relief layout and apply simulated annealing algorithm for optimization. Experiments show that our method is effective, in terms of layout arrangement for bas-relief generation. In addition, this method can synthesize a few models arrangement and investigate which evaluation indicators will affect the aesthetic perception of the bas-relief.

Detecting color boundaries on 3D surfaces by applying edge‐detection image filters on a quad‐remeshing

“…They computed the best viewport of the 3D mesh to obtain the limited range for placing the image, and then defined the criteria considering the modulated area and deformation of the mesh. Mao et al 15 proposed an approach to tackle the problem of relief layout arrangement. They first identified the evaluation indicators to account for different aesthetic factors, and modeled the goodness of each indicator.…”

“…This is a new way for users to edit mesh surfaces. Figure 17d shows a relief sculpture made by Mao et al 15 . They did not consider the information of mesh color in their work.…”

“…In another category of edge detection in 3D space, an edge on a 3D mesh surface can be used to represent a location in which the curvature of the geometric surface changes, such as ridges and valleys, 13 demarcating curves, 14 and relief edges. 15 However, these studies only consider the geometric information of the mesh, not the color information. In a third category of edge detection in 3D space, edge detection is used in the calculation of silhouettes and outlines in non-photorealistic rendering.…”

“…Figure 17d shows a relief sculpture made by Mao et al. 15 They did not consider the information of mesh color in their work. In implementation, we manually choose a vertex inside the boundary, and then use the region growing algorithm to select all the vertices that are in the contour formed by the boundaries.…”
