VIG Dataset

This repository includes Visually Indicated sound Generation (VIG) dataset mentioned in Visually Indicated Sound Generation by Perceptually Optimized Classification (Best paper in ECCV MULA workshop 2018).

Introduction

Visually Indicated Sound Generation aims to predict visually consistent sound from the video content. Previous methods in Visually Indicated Sounds addressed this problem by creating a single generative model that ignores the distinctive characteristics of various sound categories. Nowadays, state-of-the-art sound classification networks are available to capture semantic-level information in audio modality, which can also serve for the purposeof visually indicated sound generation.

Framework

We explore generating fine-grained sound from a variety of sound classes, and leverage pre-trained sound classification networks to improve the audio generation quality. We propose a novel Perceptually Optimized Classification based Audio generation Network (POCAN), which generates sound conditioned on the sound class predicted from visual information. Additionally, a perceptual loss is calculated via a pre-trained sound classification network to align the semantic information between the generated sound and its ground truth during training. The framework of POCAN is shown below.

VIG dataset download

Data processing is based on Python 2.7

We provide the Youtube ID for each video in the file vig_dl.lst. You may use tools like youtube-dl to download these videos (A sample download script download_vig.py is provided in this repository). In file vig_dl.lst, each youtube video is mapped to a file ID in each line. The files vig_train.lst and vig_test.lst specify the training and test videos by these file IDs respectively. For annotation files, we provide start time (key name start_time), end time (key name end_time) and sound class label (key name vig_label) in the file vig_annotation.pkl. The sound class is mapped to a class ID in the annotation file. The map between class name and class ID is provided in the file vig_class_map.pkl.

Some demo video clips as well as sound waveform and spectrogram are shown in the figure below.

Performance of POCAN on VIG

We choose the recall at top K (R@K) as the metric for retrieving sound in the test set in VIG. The performance of POCAN is listed in the table below.

Model	K = 1	K = 5	K = 10
Owens et al [1]	0.0997	0.2888	0.4640
POCAN	0.1223	0.3625	0.4802
