Title
(EN) METHOD AND APPARATUS FOR GENERATING INFORMATION
Abstract
(EN)

A method and an apparatus for generating information are provided. The method comprises: acquiring a to-be-detected image and facial region information used to indicate a facial region in the to-be-detected image and obtained by previously performing face detection on the to-be-detected image; extracting a facial image from the to-be-detected image based on the facial region information; inputting the facial image into a pre-trained convolutional neural network to obtain image feature information, the convolutional neural network being used to extract an image feature; analyzing the image feature information to determine a probability of each pixel point included in the facial image belonging to a category indicated by each category identifier in a preset category identifier set; and generating information for indicating the category to which the each pixel point belongs based on the probability. This embodiment implements generation of information full of pertinence.
