1. A method for characterizing cell motion, comprising: receiving image data corresponding to a set of images of a cell culture captured at a set of time points; determining a multi-peak motion signal for a cell subpopulation of the cell culture, across a subset of the set of images; generating a comparison between the multi-peak motion signal and a threshold condition; determining a resting signal for the cell subpopulation, based upon the comparison, across a subset of the set of images, the resting signal associated with a reference image; determining a single-peak motion signal based upon the set of images, the set of time points, and the reference image; and determining a set of motion features of the cell subpopulation, based upon at least one of the multi-peak motion signal and the single-peak motion signal, and the set of time points, thereby characterizing cell motion.
