Abstract:

面向地震图像解释中的具体问题,开展图像融合算法研究,增强目标识别的准确性,提高对地震图像的解译能力.设计了一种具备对称性、短支撑性、二阶消失矩和正交性的高性能多小波基,提出了其并行融合算法实现.算法考虑了对配准误差的适应性问题,提高了图像空间频率.从实验结果来看,图像的整体和细节特征比单小波融合方法有较大的提高.通过将地震图像融合技术与并行程序设计相结合,在多核处理器下采用虚拟节点技术搭建多机并行图像融合平台.实验结果表明:针对多核系统的并行融合方法省去了并行处理的数据寻址时间,相比并行化前,算法执行时间随着节点数增加而减少,并且各并行操作更为规范、简洁,符合算法操作规则性强的实现特点.
