A method and a device for classifying an image are provided. The method includes: extracting a set of features as a feature vector, wherein the extracting includes: for each feature of the feature vector, determining a plurality of first areas arranged along a first axis and a plurality of second areas arranged along a second axis intersecting with the first axis; calculating the first differences between the sums of the pixels or the mean values of the plurality of first areas and the second differences between the sums of the pixels or the mean values of the plurality of second areas; and calculating the magnitude of gradient and the direction of gradient based on the first differences and the second differences, so as to form each feature; and according to the extracted feature vector, classifying the image. |
