Abstract
(EN)
The embodiment of the invention discloses an information generating method and a device thereof. A specific implementation mode of the method comprises the steps of acquiring a to-be-detected image and the face area information used for indicating a face area in the to-be-detected image obtained through performing human face detection on the to-be-detected image in advance; based on the face areainformation , extracting a face image from the to-be-detected image; inputting the face image into a pre-trained convolution neural network to obtain the image feature information, wherein the convolution neural network is used for extracting image features; analyzing the image feature information, determining the probability that each pixel point included in the face image belongs to a category indicated by each class identifier in a preset class identification set; generating the information for indicating the category to which the pixel point belongs on the basis of the probability. According to the implementation mode, the targeted information generation is realized.
