Sight To Sound: An End-To-End Approach For Visual Piano Transcription

Automatic music transcription has primarily focused on transcribing audio to a symbolic music representation (e.g. MIDI or sheet music). However, audio-only approaches often struggle with polyphonic instruments and background noise. In contrast, visual information (e.g. a video of an instrument being played) does not have such ambiguities. In this work, we address the problem of transcribing piano music from visual data alone. We propose an end-to-end deep learning framework that learns to automatically predict note onset events given a video of a person playing the piano. From this, we are able to transcribe the played music in the form of MIDI data. We find that our approach is surprisingly effective in a variety of complex situations, particularly those in which music transcription from audio alone is impossible. We also show that combining audio and video data can improve the transcription obtained from each modality alone.
