I´m trying to extract heart rate from NIR video data by implementing the algorithm explained in http://openaccess.thecvf.com/content_cvpr_2018_workshops/papers/w27/Nowara_SparsePPG_Towards_Driver_CVPR_2018_paper.pdf. In section 3.3 a low-rank Matrix Z is seperated in a matrix X, which is jointly sparse in columns to exclude frequencies generated by noise and a matrix E, which is zero or non-zero in its columns to exclude regions, which are not appropriate for heart rate extraction. This is achieved by obtaining a solution using FISTA.Optimization problem to solve I have found this python library https://github.com/JeanKossaifi/FISTA and this MATLAB library https://github.com/tiepvupsu/FISTA, but dont know how to implement this specific case, with these libraries. Could somebody help me with this?
