Detection of cells from calcium imaging data by non-negative matrix factorization
نویسندگان
چکیده
A method for detecting the position of cells from multi-cellular calcium imaging data using non-negative matrix factorization is presented. Contamination of the background in the cell signals is effectively avoided by treating it as a distinct component with a constraint. The validity of the method is tested upon simulated and real calcium imaging data. Keywords— Calcium imaging, cell sorting, nonnegative matrix factrization

Iterative Weighted Non-smooth Non-negative Matrix Factorization for Face Recognition
Non-negative Matrix Factorization (NMF) is a part-based image representation method. It comes from the intuitive idea that entire face image can be constructed by combining several parts. In this paper, we propose a framework for face recognition by finding localized, part-based representations, denoted “Iterative weighted non-smooth non-negative matrix factorization” (IWNS-NMF). A new cost fun...
متن کاملA new approach for building recommender system using non negative matrix factorization method
Nonnegative Matrix Factorization is a new approach to reduce data dimensions. In this method, by applying the nonnegativity of the matrix data, the matrix is decomposed into components that are more interrelated and divide the data into sections where the data in these sections have a specific relationship. In this paper, we use the nonnegative matrix factorization to decompose the user ratin...
متن کاملVoice-based Age and Gender Recognition using Training Generative Sparse Model
Abstract: Gender recognition and age detection are important problems in telephone speech processing to investigate the identity of an individual using voice characteristics. In this paper a new gender and age recognition system is introduced based on generative incoherent models learned using sparse non-negative matrix factorization and atom correction post-processing method. Similar to genera...
متن کاملFast Constrained Non-negative Matrix Factorization for Whole-Brain Calcium Imaging Data
Advances in optical recording technologies allow whole-brain recordings with single cell resolution of small animals, such as larval zebrafish. A crucial step for further neural analysis is the move from voxel-space to neural-space, i.e. the detection of all neurons and extraction/demixing of how each neurons activity evolves in time. The sheer amount of data has led experimenters towards simpl...
متن کاملSpectral Separation of Quantum Dots within Tissue Equivalent Phantom Using Linear Unmixing Methods in Multispectral Fluorescence Reflectance Imaging
Introduction Non-invasive Fluorescent Reflectance Imaging (FRI) is used for accessing physiological and molecular processes in biological media. The aim of this article is to separate the overlapping emission spectra of quantum dots within tissue-equivalent phantom using SVD, Jacobi SVD, and NMF methods in the FRI mode. Materials and Methods In this article, a tissue-like phantom and an optical...
