人眼在搜索目标时,先基于此前的扫视经验粗略扫视,找到可能有目标的位置,再进行详细搜索.前者的扫视可称为基于时间上下文信息的扫视,后者可称为基于位置上下文信息的搜索.受人眼这种目标搜索模式启发,本文提出一种结合强化学习的时空上下文目标搜索方法.该方法基于强化学习搜索策略构建时间上下文模块,获得时间上下文信息;再通过构建一个自适应多尺度窗口提取位置上下文信息,两种信息在目标搜索过程中交替配合,完成目标搜索.实验结果表明,该方法在MS COCO数据集上较基准方法提升了2.9%,且可在5个搜索次数内找到目标.
When searching for a object
the human eye first roughly scans based on previous scanning experience to find potential locations for the object
and then conducts a detailed search. The former can be referred to as scanning based on temporal contextual information
while the latter can be referred to as searching based on location contextual information. Inspired by this
this paper proposes a rapid search method for small objects based on reinforcement learning that integrates spatio-temporal context information. The method builds a temporal context module based on a reinforcement learning search strategy to simulate the human eye's ability to obtain and utilize empirical information
then constructs an adaptive multi-scale window to extract location context information to simulate the human eye's ability to search carefully at possible locations. The two kinds of information cooperate alternately in the object search process to complete the object search. The experimental results show that the proposed algorithm brings around 2.9% gain on MS COCO benchmark
and can find an object within five search counts.
