一种基于定位和非对称补偿的伪装目标分割方法

伪装是欺骗观察者感知系统的一种手段, 善于伪装的个体在纹理特征上与背景具有高度的相似性。为解决前景与背景因相似而导致的像素归属歧义, 提出一种基于定位和补偿网络(locating and compensation network, LCNet)的伪装目标分割网络。该方法效仿了捕食者从搜索→确立→聚焦的寻猎过程, 涵盖双主干网的强感知提取、定位模块的双注意力以及级联的非对称补偿模块的细化像素模糊。实验表明, 在4种评价指标下, LCNet在3个具有挑战的伪装数据集上都显著优于现有的6种最新模型, 具有较高分割性能。

A method of camouflaged object segmentation with locating and asymmetric compensation

Camouflage is the instinct to deceive the perception of the observer, which presents the high similarity of the textural characteristics with the surroundings. In order to address the ambiguous regions generated by the similarity between background and foreground, this paper proposes a camouflaged object segmentation network based on locating and compensation network (LCNet). Inspired by predator process: Search→Establish→Focusing, the paradigm of the proposed method is achieved via dual-backbone with the strong sense of knowledge extraction, locating module with double attention, and cascading asymmetric compensation module with pixel refining. Experimental results have shown that the performances of LCNet are superior than six state-of-the-art models at the three major challenging camouflaged datasets in terms of four metrics, and the effectiveness of LCNet is demonstrated.
