Systems and methods for identifying waveguide defects

Systems and methods are described herein for waveguide defect detection. In some examples, a statistical value of pixels of a number of image locations in one or more images of the waveguide can be computed. An extremity matrix can be generated based on an anomaly detector model and statistical pixel data that includes statistical values computed for respective image locations in the one or more images of the waveguide. A decision can be made to determine whether the waveguide is a conforming or a non-conforming waveguide based on the extremity matrix and a set of thresholds. In some examples, the statistical value is a mean intensity value or an average intensity value.
