摘要:
在视频描述任务中,常见问题之一是对象描述不够具体,主要原因在于模型没有充分学习视频中的对象信息。同时,视频包含了丰富的特征信息,如对象信息、运动信息和上下文信息,这使得如何提升模型在生成描述时学习关键信息的能力成为一项具有挑战性的任务。为解决上述问题,本文提出了一种基于增强对象学习和注意力网络的方法。首先,设计了一种新的增强对象学习模块,旨在充分学习视频中的对象信息,从而实现对视频内容的准确描述;其次,构建了一种注意力网络,致力于有效关注不同类型的信息,以提升模型在生成描述时学习关键信息的能力。在MSVD和MSR-VTT数据集上的实验中,本文方法生成的描述展现出更高的具体性和准确性,同时在各项评价指标上均超过了目前的先进方法,有效验证了该方法的可行性。
