Sparsity enhanced MRF algorithm for automatic object detection in GPR imagery by Changpu Meng, Jie Yang

“…Then, we propose a novel detection algorithm by introducing the sparsity constraint to the standard MRF model. Specifically, the traditional approach finds it difficult to determine the central target due to the influence of different neighbors from the imaging area. …”

Accuracy and repeatability of joint sparsity multi-component estimation in MR Fingerprinting by L. Nunez-Gonzalez, M.A. Nagtegaal, D.H.J. Poot, J. de Bresser, M.J.P. van Osch, J.A. Hernandez-Tamames, F.M. Vos

“…Often, voxel-wise measurements are made, assuming a single tissue-type per voxel. Alternatively, the Sparsity Promoting Iterative Joint Non-negative least squares Multi-Component MRF method (SPIJN-MRF) facilitates tissue parameter estimation for identified components as well as partial volume segmentations. …”
