基于多粒度序贯三支决策的代价敏感目标检测方法
Cost-Sensitive Multi-Granularity Sequential Three-Way Decision for Object Detection
摘要
Abstract
Many studies on object detection attempt to achieve a low misclassification error and they assume the misclassification costs are the same.Such assumption is unreasonable in many real-world applications due to the different costs and insufficient object information.Imbalanced misclassification costs and insuffi-cient information may lead to higher cost.To solve the issue,we propose a cost-sensitive multi-granularity sequential three-way decision method for Object Detection.The proposed method is based on sequential three-way decision(3WD)considering multi-granularity features.It develops a decision strategy which can minimize the total cost in the detection process.In each step,it optimizes the misclassification cost and makes delayed decision if the object information is insufficient.In the method,the object information con-verts from rough granularity to precise granularity in object detection and it may reach more reasonable de-cision.The experiments on several object detection databases are conducted to validate the effectiveness of the proposed method.关键词
