Abstract

In this chapter, we combine adaptive sampling in conjunction with video analogies (VA) to correct the audio stream in the karaoke environment \(\kappa= \left \{\kappa (t) :\ \kappa (t) = \left (U(t),\ K(t)\right ),\ t \in \left ({t}_{s},\ {t}_{e}\right )\right \}\) where t s and t e are start time and end time respectively, U(t) is the user multimedia data. We employ multiple streams from the karaoke data \(K(t) = \left ({K}_{V }(t),\ {K}_{M}(t),\ {K}_{S}(t)\right )\), where K V (t), K M (t) and K S (t) are the video, musical accompaniment and original singer’s rendition respectively along with the user multimedia data \(U(t) = \left ({U}_{A}(t),{U}_{V }(t)\right )\) where U V (t) is the user video captured with a camera and U A (t) is the user’s rendition of the song. We analyze the audio and video streaming features \(\Psi (\kappa ) = \left \{\Psi (U(t),\ K(t))\right \} = \left \{\Psi (U(t)),\ \Psi (K(t))\right \} = \left \{{\Psi }_{U}(t),\ {\Psi }_{K}(t)\right \}\), to produce the corrected singing, namely output U (t), which is made as close as possible to the original singer’s rendition. Note that Ψ represents any kind of feature processing.
