Correlative Closeness Function for Eye Array

We have presented a new time domain signal processing algorithm accompanied with a novel microphone array structure for sound source localization in three-dimensional spaces. Our localization methodology utilizes concepts of pinhole and lens cell structures and closeness functions; moreover it has some analogy to the eye in the localization of the light rays. Later, we presented difference based category of closeness functions. Current paper describes a correlative based category of closeness functions and compares its experimental results with previously presented closeness functions.
