Abstract
Sunken relief is an art form whereby the depicted shapes are sunk into a given flat plane with a shallow overall depth. In this paper, we propose a sunken relief generation algorithm based on a single image. Our method starts from a single image. First, we smoothen the image with morphological operations such as opening and closing operations and extract the feature lines by comparing the values of adjacent pixels. Then we apply unsharp masking to sharpen the feature lines. After that, we focus on local information enhancement and smoothing to obtain an image that with little burrs and jaggies. Differential operations are necessary to produce the perceptive relief effect. Finally, we construct the sunken relief surface by triangularization, by which two-dimensional information is transformed into a three-dimensional model. The results demonstrate that our method is simple and efficient.
