Abstract A new reconstruction operator based on secondgeneration connectivity mask was proposed to efficiently utilize the multichannel information and improve the filtering performance of reconstruction operator. The connectivity mask image, reconstruction mask image and reconstruction marker image are firstly obtained based on different channel information and constrictions. According to the maskbased secondgeneration connectivity, the proposed operator relabels the connected components in the reconstruction mask image. By partition and clustering, a new connectivity space is formed from the reconstruction mask image. In the new connectivity space, some connected components are selectively reconstructed according to the corresponding regions in the marker image. By flexibly selecting the connectivity mask and the mark image, and effectively utilizing the grads information, color information and multichannel information, the maskbased reconstruction operator can solve the problem of information restriction of the traditional reconstruction operator.

基于连通掩模的重构开算子及应用
为了有效地综合利用目标的多种信息进行融合,以提高重构开算子的滤波能力,提出一种新的基于二代连通掩模的重构开算子.基于不同的通道信息和约束条件得到连通掩模图、重构模板图和标识图,该算子根据二代连通的性质,由连通掩模图重新标识重构模板图中的连通成分,通过分割和聚类重构模板图形成新的连通空间,在该连通空间中标识图中的连通成分,有选择地重构模板图.通过灵活选择连通掩模和重构标识,融合图像多梯度信息、颜色信息和多通道信息,基于连通掩模的重构开算子有效地改善了传统形态重构算子标识图信息受限的问题.
