1. A method for detecting and localizing multiple anatomical landmarks in medical images, comprising: receiving an input requesting identification of a plurality of anatomical landmarks in a medical image; applying a multi-landmark detector to the medical image to simultaneously identify a plurality of landmark candidate locations for each of the plurality of anatomical landmarks; for each of the anatomical landmarks, applying a landmark-specific detector to each of its landmark candidate locations, wherein the landmark-specific detector assigns a score to each of the landmark candidate locations, and wherein landmark candidate locations having a score below a predetermined threshold are removed; automatically calculating spatial statistical correlation of each landmark candidate location based upon each of the remaining candidate locations to determine, for each of the anatomical landmarks, the candidate location that most accurately identifies the anatomical landmark; and for each of the anatomical landmarks, outputting the landmark candidate location that most accurately identifies the anatomical landmark.
