1. A method for producing a composite photo by replacing a face in a first digital image with a face from a second digital image comprising:

  • a. automatically detecting one or more faces in the first digital image;

    b. identifying at least one target face from the detected faces that needs to be replaced;

    c. automatically detecting one or more faces in the second digital image;

    d. identifying at least one source face from the second image detected faces for replacing the target face;

    e. automatically locating facial features in both the first and second digital images;

    f. using the located facial features from the target and source faces to perform facial geometry correction using facial features located on the target face and the source face to produce a geometrically corrected source face, and perform appearance correction on the geometrically corrected source face under a plurality of automatically determined parameters to produce a corrected source face;

    g. replacing the target face with the corrected source face and blending the corrected source face into the first digital image by;

    i. producing a source face mask for the corrected source face;

    ii. producing an eroded source face mask;

    iii. replacing pixels in the target face with pixels in the corrected source face based on the eroded source face mask; and

    iv. blending the corrected source face into the first image around the boundary pixels indicated by the eroded source face mask; and

    h. producing the composite photo from the corrected source face image.
