论文摘要
在这项工作中,我们解决了与点级注释相计数的几个射击多类对象的问题。提出的技术利用了一种不可知的注意机制,该机制依次关注图像中的对象并提取其相关特征。此过程用于改编的基于原型的几射击方法,该方法使用提取的功能将每个功能分类为支持集图像中存在的类别或背景中的一个类。该提出的技术对点级注释进行了训练,并使用了一种新颖的损耗函数,该功能将模型的依赖性依赖性依赖性依赖性和类不足的方面来帮助完成少量对象计数的任务。我们在包括FSOD和MS COCO在内的各种对象计数/检测数据集上介绍了结果。此外,我们引入了一个新的数据集,该数据集是专门设计用于弱监督的多类对象计数/检测的,并且与现有数据集相比,每个图像的类/实例的分布都有很大不同的类别和分布。我们通过测试我们的系统在类别的完全不同的培训中测试系统来证明我们的方法的鲁棒性。
In this work, we address the problem of few-shot multi-class object counting with point-level annotations. The proposed technique leverages a class agnostic attention mechanism that sequentially attends to objects in the image and extracts their relevant features. This process is employed on an adapted prototypical-based few-shot approach that uses the extracted features to classify each one either as one of the classes present in the support set images or as background. The proposed technique is trained on point-level annotations and uses a novel loss function that disentangles class-dependent and class-agnostic aspects of the model to help with the task of few-shot object counting. We present our results on a variety of object-counting/detection datasets, including FSOD and MS COCO. In addition, we introduce a new dataset that is specifically designed for weakly supervised multi-class object counting/detection and contains considerably different classes and distribution of number of classes/instances per image compared to the existing datasets. We demonstrate the robustness of our approach by testing our system on a totally different distribution of classes from what it has been trained on.
