Abstract: This application provides an eye bag detection method and apparatus, and relates to the field of facial recognition technologies. The method includes: obtaining a to-be-detected image, where the to-be-detected image includes an eye bag region of interest ROI; detecting the eye bag ROI by using a preset convolutional neural network model, to obtain an eye bag detection score and eye bag position detection information; and when the eye bag detection score is within a preset score range, annotating the to-be-detected image based on the eye bag detection score and the eye bag position detection information to obtain eye bag annotation information. According to the technical solutions provided in this application, a position and a score of an eye bag can be accurately recognized. In this way, accuracy of recognizing the eye bag is significantly improved.
