收藏资源简介:
VGG-MonoAudio 是一个专为文本条件选择性视频到音频(V2A)生成设计的评估基准数据集。该数据集包含视频(包含多个可见声源)、文本(识别目标声源)和音频(仅包含干净、孤立的目标声音)的三元组。数据集通过从VGGSound和UnAV-100中视觉混合单源视频片段构建,同时仅保留目标声源的单一音频轨道。这种设计解决了现有数据集的局限性,如不可分离的音频混合或离屏噪声,使其成为评估对象选择性声音生成的精确标准。所有单源视频片段均经过人工专家的仔细筛选和验证。数据集包含1,071个8秒的混合视频,分为560个类间对和511个类内对,源自67个精选视频,包含39个独特的文本标签和8个声音类别。视频格式为1280×720分辨率,H.264编码,25帧/秒;音频为单声道,AAC编码,16kHz。数据集结构包括混合视频、目标音频、音频特征缓存和元数据文件。元数据文件包含文件名、目标文件、配对文件、目标位置、起始时间、标签、目标类别、配对类别和配对标签等字段。数据集的使用受原始Creative Commons Attribution 4.0 International License (CC BY 4.0)和源视频(YouTube)的服务条款约束。
VGG-MonoAudio is an evaluation benchmark dataset specifically designed for text-conditioned selective video-to-audio (V2A) generation. This dataset contains triplets of videos (with multiple visible sound sources), text prompts (for identifying target sound sources), and audio (only containing clean, isolated target sounds). The dataset is constructed by visually mixing single-source video clips from VGGSound and UnAV-100, while retaining only the single audio track of the target sound source. This design addresses the limitations of existing datasets, such as inseparable audio mixtures or off-screen noise, making it an accurate benchmark for evaluating object-selective sound generation. All single-source video clips have been carefully screened and verified by human experts. The dataset consists of 1,071 8-second mixed videos, which are divided into 560 inter-class pairs and 511 intra-class pairs, derived from 67 selected videos, covering 39 unique text labels and 8 sound categories. Videos are formatted with a resolution of 1280×720, encoded in H.264, with a frame rate of 25 FPS; audio is monaural, encoded in AAC, with a sampling rate of 16kHz. The dataset structure includes mixed videos, target audio, audio feature caches, and metadata files. Metadata files contain fields such as file name, target file, paired file, target location, start time, label, target category, paired category, and paired label.
