Adding Various Types of Noise to Images

This program adds multiple types of noise to images, including Gaussian noise, salt-and-pepper noise, additive and multiplicative noise, as well as various mixed noise combinations, for testing other image processing applications.

Root-MUSIC Algorithm MATLAB Implementation

While traditional MUSIC algorithm provides super-resolution capability, it fails in modern pulse radar systems where additive noise often exhibits colored noise characteristics. This article presents an enhanced approach - the Root-MUSIC algorithm, which replaces spectral search in conventional MUSIC with polynomial root-finding techniques. The implementation includes MATLAB code demonstrating signal covariance matrix estimation, eigenvalue decomposition, and polynomial coefficient extraction for improved direction-of-arrival estimation.
