METHOD AND SYSTEM FOR CHARACTERIZING CELL POPULATIONS
First Claim
1. A method for characterizing a cell population including a set of cell subpopulations, the method comprising:
- at a processing system, receiving image data corresponding to a set of images of the cell population captured at a set of time points;
at the processing system, generating an analysis based upon processing the set of images according to;
a cell stage classification module configured to automatically identify a cell stage of each of the set of cell subpopulations;
from the analysis, determining a set of parameters characterizing the cell population; and
at the processing system, generating an indication of quality of the cell population based upon a comparison between at least one parameter of the set of parameters and a set of reference values.

Abstract
A method and system for characterizing a cell population including a set of cell subpopulations, the method comprising: at a processing system, receiving image data corresponding to a set of images of the cell population captured at a set of time points; at the processing system, generating an analysis based upon processing the set of images according to: a cell stage classification module configured to automatically identify a cell class of each of the set of cell subpopulations, and a cell graph representation module configured to characterize geometric and spatial features of the set of cell subpopulations; from the analysis, determining a set of parameters characterizing the cell population; and generating an indication of quality of the cell population based upon a comparison between at least one parameter of the set of parameters and a set of reference values.

8. A method for characterizing a cell population including cells of at least one of a set of cell stages, the method comprising:
-
at a processing system, receiving image data corresponding to a set of images of the cell population captured at a set of time points; and at the processing system, generating an analysis based upon processing the set of images according to a cell stage classification module configured to automatically identify a cell stage of the set of cell stages, wherein processing the set of images includes; partitioning each image in the set of images into a set of pixel subsets, for each pixel subset in the set of pixel subsets for each image, generating a feature vector associated with each pixel subset, thereby producing a set of feature vectors corresponding to the set of pixel subsets for each image in the set of images, and training a machine learning classifier, with a training dataset, to identify each of the set of cell stages of the cell population captured in the set of images, using the set of feature vectors for each image in the set of images, thereby characterizing the cell population. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)

16. A method for characterizing a cell population including a set of cell subpopulaitons, the method comprising:
-
at a processing system, receiving image data corresponding to a set of images of the cell population captured at a set of time points; at the processing system, generating an analysis based upon processing the set of images according to a cell graph representation module configured to characterize geometric and spatial features of the set of cell subpopulations, wherein processing includes; at a cell cluster segmentation module, segmenting, from at least one image of the set of images, a set of regions corresponding to the set of cell subpopulations of the cell population, each region defined by a set of nodes and a set of edges, and determining a set of parameters characterizing the cell population based upon an analysis of the set of nodes and the set of edges of at least one of the set of regions. - View Dependent Claims (17, 18, 19, 20)
