在卡通形象中,装饰线条和装饰边缘是传达卡通形象语义信息的重要元素。在本研究中,我们提出了一种同时提取卡通图像装饰线和边缘的方法。首先,利用Hessian矩阵计算图像中与装饰线垂直的方向。然后,对图像的高斯二阶导数进行非极大值抑制,定位可能的装饰线中心;其次,我们使用方向过零(第一个高斯导数在预先计算方向上的过零)来验证装饰线的存在性。最后,将装饰线和一阶高斯导数非极大值抑制检测到的边缘融合在一起。实验结果表明,对于复杂的卡通图像,我们的方法比文献中已有的方法更有效。
Decorative Lines and edges in a cartoon image are the most important elements to convey its semantic information. In this study, we propose a method to extract both decorative lines and edges of the cartoon image at the same time. Firstly, we use the Hessian matrix to compute the direction perpendicular to the decorative lines in the image. Then, non-maximum suppression is applied to the image's second derivative of Gaussian to locate the possible decorative line's center. Secondly, we use directional zero-crossing (the zero-crossing of the first Gaussian derivative on the precomputed direction) to verify the existence of the decorative lines. Finally, decorative lines and the edges detected by non-maximum suppression on the first Gaussian derivative are fused together. The experimental results show that our method is more effective than other existed methods in literature for complicated cartoon images.
