Abstract
A method for detecting defects in battery cells includes receiving an X-Ray radiographic image of a battery cell and segmenting the X-Ray radiographic image into regions of interest using a classifier. The method includes processing the segmented X-Ray radiographic image using the classifier to identify features of the battery cell, detecting whether one or more of the features in the processed X-Ray radiographic image is defective using the classifier, and determining using the classifier whether the battery cell is defective based on whether one or more of the features in the processed X-Ray radiographic image is defective.
