A piecewise smooth extension to Tikhonov regularization, which can be implemented as a fixed-lag or fixed-interval smoother. The theoretical justification of this problem using constrained least squares and the optimal parameter selection details. The relationship between the proposed scheme and Lipschitz regularity and Wiener smoothing. A detailed case-study on ECG denoising, comparing the proposed versus state-of-the-art methods for ECG denoising.
