The invention provides an age judgment method and device based on a face image, electronic equipment and a computer readable storage medium. The age judgment method comprises the steps: inputting the face image into a trained age judgment model, and obtaining age group category information output by the age judgment model and probability values of different ages, performing weighted summation on the probability values of different ages to obtain age information; judging whether the age information is matched with the age group category information or not; if not, judging whether the age information is within the age group range corresponding to the maximum age group in the age group category information or not, and judging whether the age group category information is the minimum age group or not; if so, carrying out calibration processing on the age information to obtain calibrated age information; and determining that the calibration age information and the age group category information indicate the age of a person in the face image. According to the scheme, accurate age judgment can be achieved by executing the age judgment models of the two classification tasks.
Description
technical field [0001] The present application relates to the technical field of image processing, and in particular to a method and device for judging age based on a face image, electronic equipment, and a computer-readable storage medium. Background technique [0002] With the development of face recognition technology, users have higher and higher requirements for recognition of face attributes, such as recognition of face age, recognition of face gender, recognition of face happiness, etc. Among them, identifying the age of faces helps to collect user information of different age groups and analyze the popularity of products of different age groups. [0003] In related schemes, age judgment methods can be roughly divided into regression tasks and classification tasks. In regression tasks, age is modeled as a continuous value, and age-related features can be extracted from face images through CNN (Convolutional Neural Networks) or custom feature extraction methods, and t...
