We propose a new region growing technique starting fromthese boundary vertices leading to a segmentation of the surface thatis subsequently simplified by a region-merging method. ...
Experiments indicatethat our algorithm segments a broad range of 3D models at aquality comparable to existing algorithms. ...

We also conducted three large-scale, wide-ranging perceptual studies on the perception of harmonic colors and harmonization algorithms. ...
We present a palette-based framework for color composition for visual applications. Color composition is a critical aspect of visual applications in art, design, and visualization. ...
For further improvement, our approach could be parallelized by dividing the image into tiles, since the convex hull of a set of convex hulls is the same as the convex hull of the underlying data. ...

The decomposition is mainly based on human visual perception, which is referred to as the basic capability of the human visual system to derive relevant groupings and structures from 3D objects without ...
We should select several feature points which meet human perception, so we obtain the points on the convex hull (see in Figure 8 (c)) and then refine them by further clustering (i.e. k-nearest neighborhood ...
