Questions tagged [source-separation]

Source separation is the process of separating (or un-mixing) the source components in a polyphonic and possibly multitimbral audio signal.

Source separation is a discipline within Digital Signal Processing concerned with the isolation (and possible removal) of source components of a complex signals such as polyphonic and multi-timbral audio signals.

The source separation process can be considered to be the inverse of mixing. However, the process of mixing signals loses information, and a source separation algorithm attempts to reconstruct the missing parts. For this reason, the process is never perfect, and artefacts result.

A common commercial application of audio source separaton is the removal of vocals from pop-songs in order to create karaoke backings. It is also an important tool used in Music Information Retrieval (MIR). Audio source separation is a subject of considerable current academic interest.

What does entropy mean in this context?

I'm reading an image segmentation paper in which the problem is approached using the paradigm "signal separation", the idea that a signal (in this case, an image) is composed of several signals (objects in the image) as well as noise, and the task…
