Few-Shot Object Detection Based on Fusion of Classification Correction and Sample Amplification
摘要
Abstract
Existing few-shot object detection methods often have the problem of data distribution shift when amplifying samples,and the performance of classification tasks is easily affected by localization tasks.Aiming at the above problems,a new few-shot object detection algorithm is proposed based on the Faster R-CNN framework.The classification correc-tion module(CCB),sample amplification module(SAB),and gradient control layer(GCL)are introduced to improve performance.CCB uses an offline strong classification network to correct the final results of the detector.SAB uses the base class information to modify the distribution of the new class samples in the feature domain,so as to complete the am-plification of the new class samples by sampling from the modified distribution.In gradient backpropagation,the informa-tion of the base class and new class received by the backbone network are restricted by GCL.The experimental results on PASCAL VOC and COCO datasets show that,compared with the latest known algorithm results,the proposed few-shot object detection algorithm improves the detection effect when the number of samples is small.The maximum improve-ment can reach 5.1%on PASCAL VOC,a public dataset.It also reaches up to 1.9%improvement on the more difficult dataset COCO.Therefore,the proposed few-shot detection framework has good robustness and generalization ability at the same time.关键词
