1. A method for detecting defects in imaging arrays comprising arrays of pixels, the method comprising,obtaining a set of images acquired by an imaging array, each image comprising a set of pixel values corresponding to pixels of the image;

  • taking each of a plurality of images in the set as a current image and obtaining for at least one of the pixels, for each of one or more of a plurality of defect types, a corresponding updated probability, the updated probability based at least in part upon;

    a pixel value corresponding to the at least one pixel;

    statistics of pixel values of other pixels in the current image; and

    one or more prior probabilities that the one of the pixels has the corresponding defect type.
