METHODS AND APPARATUS FOR ASSESSING EMBRYO DEVELOPMENT

摘要

A computer-implemented method of processing a time series of images of an embryo to determine estimated timings for a plurality of developmental events for the embryo, wherein the method comprises: determining feature information for each of the images, the feature information for each image representing the content of the image; establishing machine learned classifiers for associating each of the images with a respective likelihood of the image being associated with (i.e. representing) one or more of the plurality of developmental events based on the feature information for the image; applying the machine learned classifiers to the feature information for each of the images to determine a respective likelihood of the image being associated with one or more of the plurality of developmental events; and determining estimated timings for the plurality of developmental events for the embryo from the respective likelihoods of the respective images being associated with respective ones of the plurality of developmental events. The method may further comprise determining an indication of a confidence estimate for the timings.
