Blind Audio-Visual Localization Dataset

 

 

Blind Audio-Visual Localization (BAVL) Dataset consists of 20 audio-visual recordings of  sound sources, which could be talking faces or music instruments. Most audio-visual recordings (19) are videos from Youtube except V8, which is from [1]. Besides, the video V7 was also used in[2][3], and V16 used in [3]. All 20 videos are annotated by ourselves in a uniform manner. Details of the video sequences are listed in Table 1. 

The videos in the dataset have average duration of 10 seconds, and they are all recorded by one camera and one microphone. The audio files (.wav) was sampled at a 16 kHz for V7, V8, V16, and 44.1 kHz for the rest. The video frames contain the sound-making object (sound source) and distracting objects (e.g. pedestrian on the street), while the audio signals  consists of the sound produced by the sound source (human speech or instrumental music), environmental noise and sometimes other sounds. The distracting objects and other irrelevant noise/sounds do not exist in all videos. The primary usage of the dataset is to evaluate the performance of sound source localization method, in the presence of distracting motions and noise.

Annotation

We provide visual annotations as illustrated in Figure 1. The locations of sound-making objects are annotated in the white region. The images of annotation have binary values, where 1 indicates the existence of sound source.
