摘要:

生活记录设备每天都在以更快的速度传播。这种增长对于开发用于提取关于佩戴设备的用户及其环境的有意义的信息的方法来说可以代表巨大的益处。在本文中,我们提出了一种半监督策略,可以轻松地发现与佩戴第一人称相机的人相关的对象。给定一个以自我为中心的视频/图像序列的摄像机获取,我们的算法使用的外观提取的卷积神经网络和对象的填充方法,允许发现对象,即使在少量的对象外观的情况下,在收集的图像。应用支持向量机过滤策略来处理大多数最先进的对象检测器发现的大部分假阳性对象候选。我们验证了我们的方法上的一个新的自我中心的数据集,4912日常图像采集4人以及PASCAL 2012年和MSRC数据集。我们获得的所有结果在很大程度上优于最先进的方法。我们公开了EDUB数据集和算法代码。

英文摘要:

Lifelogging devices are spreading faster everyday. This growth can represent great benefits to develop methods for extraction of meaningful information about the user wearing the device and his/her environment. In this paper, we propose a semi-supervised strategy for easily discovering objects relevant to the person wearing a first-person camera. Given an egocentric video/images sequence acquired by the camera, our algorithm uses both the appearance extracted by means of a convolutional neural network and an object refill methodology that allows to discover objects even in case of small amount of object appearance in the collection of images. An SVM filtering strategy is applied to deal with the great part of the False Positive object candidates found by most of the state of the art object detectors. We validate our method on a new egocentric dataset of 4912 daily images acquired by 4 persons as well as on both PASCAL 2012 and MSRC datasets. We obtain for all of them results that largely outperform the state of the art approach. We make public both the EDUB dataset and the algorithm code.
