1. An image processing method, comprising:
extracting a characteristic vector in an image to be recognized;
based on the characteristic vector of the image to be recognized, acquiring a predicted score value of the image to be recognized; and
based on the predicted score value, determining a category of an image information of the image to be recognized;
wherein the image to be recognized is a face image, and the image information is a facial expression;
wherein the step of, based on the characteristic vector of the image to be recognized, acquiring the predicted score value of the image to be recognized comprises:
by using a random-forest classifier, based on the characteristic vector of the image to be recognized, acquiring the predicted score value of the image to be recognized; and
the method further comprises:
based on characteristic vectors and grading values of image data in a training set comprised in a dataset, training the random-forest classifier;
wherein the dataset comprises the plurality of image data, and each of the image data is marked with a grading value;
the grading value of each of the image data is determined according to a category of image information comprised in the each of the image data, and different categories of the image information correspond to different grading values;
the image data are face-image data; and
the training set comprises a fifth quantity of the image data in the dataset.
