Fig. 1From: Audio source separation by activity probability detection with maximum correlation and simplex geometryScatter plot of a, b tl(q1,q2) and c, d tl(q1,q2,q3). The position of each point is according to a, b [q1,q2] or c, d [q1,q2,q3], and the color coding is according to the function value at each pointBack to article page
