This implementation features a Total Variation (TV) denoising algorithm with PDF-based corrections to resolve minor issues in conventional TV methods. The core algorithm minimizes a variational energy functional combining data fidelity and TV regularization terms, preserving edge sharpness while eliminating noise. Key improvements include gradient descent optimization with adaptive step size control and edge-preserving diffusion mechanisms. The implementation employs matrix operations for efficient computation of partial derivatives and utilizes thresholding techniques for noise suppression. Through these enhancements—including modified regularization parameters and optimized convergence criteria—the algorithm demonstrates superior performance in practical applications, offering new possibilities for image processing tasks.
