Automatic microscopic image analysis by moving window local Fourier Transform and Machine Learning [PDF]
, 2019 Analysis of microscope images is a tedious work which requires patience and time, usually done manually by the microscopist after data collection. The results obtained in such a way might be biased by the human who performed the analysis.
