However, the extreme increase in the amount of data size makes us face with a difficult of manual analysis. Consequently, a demand for automatic analysis methods for large-scale imaging data is increasing. Recently, some research groups have proposed automatic cell detection methods using machine learning approaches. Although the scalability for data size is one of the most fundamental problems in those proposed methods, within a practical time those methods cannot process large-scale data acquired with ultra-wide field-of-view microscopies recently developed. Therefore, we proposed low-computational cost cell detection (LCCD) algorithm, which can process such large-scale data within a practical time. We compared LCCD with two previously proposed methods, constrained non-negative matrix factorization and Suite2p. The detection accuracy of the LCCD was almost comparable with those of the other methods, whereas the computational time of the LCCD was a few ten times faster than those of the other methods.}, title = {大規模なイメージングデータからの細胞検出}, year = {2018} }
