摘要：本发明提出一种用于保留结构及平衡亮度的低质量焊接图像增强方法，具体步骤为：输入的低质量焊接原始图像，通过主成分分析算法形成初始光照分量图像输出；对利用相对全变分模型对初始光照分量图像进行处理，形成结构特征优化的光照分量图像输出；结构特征优化的光照分量图像再分两路，一路与原始图像一起直接代入Retinex模型求取反射分量图，另一路通过对数变换增强算法处理获取亮度优化的光照分量图；根据Retinex模型将反射分量图和亮度优化的光照分量图进行融合，得到重建图像；引入引导滤波器将初始光照分量图像作为引导图，得到最终的增强图像。本方法增强后的图像亮度分布均匀且自然，结构特征信息保留较好，没有伪影或块效应产生，图像细节更加清晰。
