1. A method for detecting ground glass objects in a digitized image comprising the steps of: providing a digitized image comprising a plurality of intensities corresponding to a domain of points on an N-dimensional grid; determining intensity statistics from a plurality of ground glass objects; determining an intensity map of the distance of each point in said image from a mean intensity of said ground glass objects wherein one or more candidate ground glass objects can be identified; determining a circularity value for each candidate ground glass object; and calculating one or more feature values wherein said candidate ground glass object is characterized.
