Model-based free-breathing cardiac MRI reconstruction using deep learned \& STORM priors: MoDL-STORM

no code implementations10 Jul 2018 Sampurna Biswas, Hemant K. Aggarwal, Sunrita Poddar, Mathews Jacob

We introduce a model-based reconstruction framework with deep learned (DL) and smoothness regularization on manifolds (STORM) priors to recover free breathing and ungated (FBU) cardiac MRI from highly undersampled measurements.

Free-breathing cardiac MRI using bandlimited manifold modelling

no code implementations24 Feb 2018 Sunrita Poddar, Yasir Mohsin, Deidra Ansah, Bijoy Thattaliyath, Ravi Ashwath, Mathews Jacob

We introduce a novel bandlimited manifold framework and an algorithm to recover freebreathing and ungated cardiac MR images from highly undersampled measurements.

Recovery of Point Clouds on Surfaces: Application to Image Reconstruction

no code implementations3 Jan 2018 Sunrita Poddar, Mathews Jacob

We introduce a framework for the recovery of points on a smooth surface in high-dimensional space, with application to dynamic imaging.

Clustering of Data with Missing Entries

no code implementations3 Jan 2018 Sunrita Poddar, Mathews Jacob

The analysis of large datasets is often complicated by the presence of missing entries, mainly because most of the current machine learning algorithms are designed to work with full data.

Recovery of Noisy Points on Band-limited Surfaces: Kernel Methods Re-explained

no code implementations3 Jan 2018 Sunrita Poddar, Mathews Jacob

We introduce a continuous domain framework for the recovery of points on a surface in high dimensional space, represented as the zero-level set of a bandlimited function.

Clustering of Data with Missing Entries using Non-convex Fusion Penalties

no code implementations6 Sep 2017 Sunrita Poddar, Mathews Jacob

Traditional algorithms for clustering data assume that all the feature values are known for every data point.

Subspace based low rank and joint sparse matrix recovery

no code implementations5 Dec 2014 Sampurna Biswas, Sunrita Poddar, Soura Dasgupta, Raghuraman Mudumbai, Mathews Jacob

We consider the recovery of a low rank and jointly sparse matrix from under sampled measurements of its columns.

Two step recovery of jointly sparse and low-rank matrices: theoretical guarantees

no code implementations5 Dec 2014 Sampurna Biswas, Sunrita Poddar, Soura Dasgupta, Raghuraman Mudumbai, Mathews Jacob

We introduce a two step algorithm with theoretical guarantees to recover a jointly sparse and low-rank matrix from undersampled measurements of its columns.
