PixelPlayer

What is PixelPlayer? 

 PixelPlayer is a groundbreaking system that learns to pinpoint the image areas producing sounds in videos, and then separates the input audio into components representing the sound of each individual pixel.  All this happens without needing any manual labeling of the videos – it's completely unsupervised learning!

Key Features and Capabilities

• Audio-Visual Source Separation and Localization:  Accurately isolates and locates different sound sources within a video.

• Pixel-Level Audio Decomposition:  Separates the input audio into components representing the sound contribution of each pixel in the video.

• Unsupervised Learning:  Learns from unlabeled video data, eliminating the need for time-consuming manual annotation.

• High-Resolution Audio-Visual Mapping:  Provides a detailed map showing the relationship between visual elements and their corresponding audio signals.
