1. A method for detecting an object in an image having a gray-level distribution, comprising the steps of:

  • a) for a subset of pixels in the image, deriving a first variable from the gray-level distribution of the image, b) for that subset of pixels, deriving a second variable from a preset reference distribution, the reference distribution being characteristic of the subject;

    c) evaluating the correspondence between the first variable and the second variable over the subset of pixels; and

    d) determining whether the image contains the object, based on the result of said evaluation step.
