摘要
针对传统能量优化方法需要逐点计算的不足,提出一种结合缝合技术的改进能量优化方法用于透视纹理图像的合成。首先,用像素块处理代替逐个像素点的运算,建立基于图像块的能量优化模型;其次,在优化过程中,引入图像缝合技术解决块处理可能存在的接缝、重叠等问题,提高合成图像质量。实验结果表明,改进的能量优化法计算效率大大提高,且可获得更好的视觉效果。
In this paper we propose an energy optimisation improvement algorithm in combination with image quilting technology for perspective texture image synthesis in light of the insufficiency of traditional pixel-based energy optimisation method. First, we replace the pixel-to-pixel calculation with patch processing of pixels, and build the image patch-based energy, optimisation model. Secondly, during the optimisation process, we introduce image quilting to solve the problems may having in patch processing such as the joint seams, overlapping, and so on, tbr improving the quality of synthesis image. Experimental results show that the proposed energy optimisation algorithm greatly improves the computation efficiency, meanwhile, a better visual effect is achieved as well.
