    Research on tensorcompletion model and algorithm based on modified correlated total variation

    • 摘要: 张量修补问题旨在从部分观测的张量数据中复原完整结构,其核心在于利用数据的先验特性进行缺失信息补全.低秩性和局部平滑性作为张量数据的两大典型先验特征,在传统恢复方法中常被作为独立约束分别利用.本文引入修正相关全变分思想,构建了一种联合低秩性与局部平滑性先验的张量修补模型.相比于传统恢复模型,该方法能够更充分地挖掘张量数据中内在耦合的低秩全局结构与局部平滑特征,在高光谱影像修复、多光谱数据重构及彩色图像复原任务中展现出显著优势.特别是在彩色图像处理中,所提模型对边缘细节的保真度以及色彩的还原度都更高.

       

      Abstract: The tensor completion problem aims at recovering the complete structure from partially observed tensor data and is centred on the use of a priori properties of the data for missing information completion. Low rank and local smoothness as two typical a priori characteristics of tensor data that is often utilised separately as independent constraints in traditional recovery methods. Paper innovatively introduce the modified correlated total variation with a joint low-rank and local smoothness. Compared with traditional recovery models, this method can more fully exploit the intrinsically coupled low-rank global structure and local smoothing features in tensor data. Demonstrate significant advantages in hyperspectral image, multispectral data and color image recovery tasks. Especially in color image processing, the proposed model has a higher fidelity of edge details as well as a higher degree of color reproduction.
