Independent Component Analysis (with MATLAB code) is a widely used method in image processing. This technique decomposes images into statistically independent components and reconstructs them, enabling effective image analysis and manipulation. The MATLAB implementation typically involves key functions like fastica for ICA computation, which utilizes optimization algorithms to maximize non-Gaussianity through approaches such as fixed-point iteration or maximum likelihood estimation. ICA finds applications in various image processing tasks including image enhancement through noise separation, feature extraction by isolating meaningful components, and image segmentation by identifying independent spatial patterns. The MATLAB code implementation offers efficient matrix operations and built-in statistical tools, making image processing workflows more streamlined and accurate through automated component separation and reconstruction procedures.
