一种改进的一致性扩散图像增强方法

An Improved Coherence Diffusion Method for Image Enhancement

  • 摘要: 一致性扩散是分析图像中定向结构的重要的预处理步骤,现有的一致性扩散图像增强方法难以识别图像中的弱边界.本文提出了一种改进的扩散方法,该方法构建了一种结合二阶方向导数信息的结构张量,能够精确分析图像中的复杂弱边界,同时与经典结构张量互为补充以检测图像的强边界.在此基础上设计了新的扩散张量,并采用了基于(加性分裂算子AOS)策略的数值计算方法.通过对比实验证明,该文算法的效果良好并具有很高的效率,实现了在去除噪声的同时精确保护图像中的强弱边界.
