PSTAIC regularization for 2D spatiotemporal image reconstruction

Deepak G Skariah, Muthuvel Arigovindan

We propose a model for restoration of spatio-temporal TIRF images based on infimal decomposition regularization model named STAIC proposed earlier. We propose to strengthen the STA…

STAIC regularization for spatio-temporal image reconstruction

Deepak G Skariah, Muthuvel Arigovindan

We propose a regularization-based image restoration scheme for 2D images recorded over time (2D+t). We design an infimal convolution-based regularization function which we call spa…

Non-convex regularization based on shrinkage penalty function

Manu Ghulyani, Muthuvel Arigovindan

Total Variation regularization (TV) is a seminal approach for image recovery. TV involves the norm of the image's gradient, aggregated over all pixel locations. Therefore, TV leads…

Compact Representation of n-th order TGV

Manu Ghulyani, Muthuvel Arigovindan

Although regularization methods based on derivatives are favored for their robustness and computational simplicity, research exploring higher-order derivatives remains limited. Thi…

Structurally Adaptive Multi-Derivative Regularization for Image Recovery from Sparse Fourier Samples

Sanjay Viswanath, Manu Ghulyani, Muthuvel Arigovindan

The importance of regularization has been well established in image reconstruction -- which is the computational inversion of imaging forward model -- with applications including d…

Fast roughness minimizing image restoration under mixed Poisson-Gaussian noise

Manu Ghulyani, Muthuvel Arigovindan

Image acquisition in many biomedical imaging modalities is corrupted by Poisson noise followed by additive Gaussian noise. While total variation and related regularization methods…
