摘要
为了获得葫芦烙画图像的计算机仿真效果,对Efros等人提出的以区块为基础的纹理传输算法进行改进,并对传输结果图像进行了有效的融合处理。该方法首先在YCbCr颜色空间中进行图像间亮度相似性匹配,通过纹理传输获得烙画图像,对传输结果图像根据Levin的最小二乘法原理,设计了一种基于动态权重控制的16点约束图像变形算法,实现了烙画图像的变形控制,然后在lαβ空间中实现了图像融合。最后将融合结果图像与泊松图像编辑方法的融合效果进行了对比分析。实验结果表明,该算法所获得的仿真结果图像接近真实葫芦烙画图像效果。
To obtain the computer simulation effects of gourd pyrography images, Efros et al. ＇s block-based texture synthesis and transfer algorithm was improved, and the resulted image was effectively fused. In this method, the pyrography image was obtained through matching the brightness histogram in YCbCr color space, and then it was deformed by 16 control points according to the principle of Levin＇s least squares to achieve the image fusion in lαβ color space. The comparison of the proposed method with the Poission image editing algorithm shows that the simulation image effect of the proposed algorithm is closer to the real gourd pyrography image effect.
