| Outline of Final Research Achievements |
Non-arbitrary, non-biased measurement is an essential property for quantification of fluorescent microscopy images. Conventional methods of the image quantification has been heavily relied on human ability of cognition, and that means there are a plenty of room to errors and inconsistencies.
To eliminate these inconsistencies and to achieve the non-arbitrary quantification, I developed a non-supervised machine learning (ML) based method that utilized median and IQR (interquartile range) intensities of the fixed-size tiles. These image tiles were successfully classified by ML to few clusters. Selection of appropriate cluster can lead an extraction of particular group of tiles, which corresponds suitable set of biologically meaningful regions. The study indicated that ML-based classification combined with descriptive statistics values of tiling images, such as median and IQR, should be a non-arbitrary, non-biased quantification of the biological and medical images.
