TITLE : PREDICTIVE CODING BASED ON LEVINSON DURBIN ALGORITHM FOR FEATURE EXTRACTION OF RED PALM WEEVIL  
AUTHORS : Betty Martin      Vimala Juliet            
ABSTRACT :

The aim of the project is to develop a system for encoding good quality sound at low bit rate. This could be accomplished by a technique called LPC. This report is a MATLAB implementation of an algorithm. LPC is one of the most powerful sound analysis technique and most useful method for encoding sound. The main objective of this work is to estimate the output sequence from a linear combination of input samples, past output samples or both. The coefficients extracted can further be matched by any of the several methods used for feature matching. This application is often used for sound identification or sound verification. In this article, work was done to extract feature of the weevil which was later used to determine its presence on palms.
