|The invention discloses a method for filtering image-based junk mails, which includes the steps of collecting a sample of the image-based junk mails to establish a training set of the image-based junk mails; extracting Fourier-Mellin invariant features of training set images from the training set as low level features of the images; carrying out analysis and dimensionality reduction to the Fourier-Mellin invariant features to obtain a low-dimensional feature vector for classification; and adopting the low-dimensional feature vector for training a classifier model and adopting the classifier model for classifying samples of new mails. The adoption of the method greatly reduces hazards caused by harassment of the junk mails for normal e-mail users.
