Nonnegative CCA for Audiovisual Source Separation
2007
Machine Learning for Signal Processing
We present a method for finding correlated components in audio and video signals. The new technique is applied to the task of identifying sources in video and separating them in audio. The concept of canonical correlation analysis is reformulated such that it incorporates nonnegativity and sparsity constraints on the coefficients of projection directions. Nonnegativity ensures that projections are compatible with an interpretation as energy signals. Sparsity ensures that coefficient weight
