The invention relates to the technical field of human face and facial feature points, in particular to a human face and feature point detection method and device, electronic equipment and a storage medium. The method comprises the following steps: extracting features of a sample image by utilizing a trunk part of a network model, and then calculating and outputting a detection box set and a facialfeature point thermodynamic diagram set; wherein loss value calculation parts of the network model comprise an anchor frame position regression unit, an anchor frame category classification unit anda facial feature point position regression unit for parallel calculation; wherein an anchor frame mechanism is introduced into the network model, a plurality of anchor frames with different scales andsizes is preset, and classification and position regression need to be carried out on each anchor frame; an optimal detection box is screened from the detection box set; points which are screened outfrom the facial feature point thermodynamic diagram set and are greater than a threshold value are used as feature points; and facial feature points corresponding to the optimal detection box are calculated through the coordinates. On the premise of ensuring high precision, redundant parameter calculation is reduced, and the real-time performance is improved.
Description
technical field [0001] The present invention relates to the technical field of human faces and facial feature points, in particular to a detection method, device, electronic equipment and storage medium for human faces and their feature points. Background technique [0002] By analyzing facial features, researchers can obtain a wealth of information, such as identity information, emotional changes, and subjective intentions, etc., and use this information to realize applications such as face recognition, expression recognition, and age recognition, and promote the realization of intelligent society. pace. [0003] Face detection technology is the first step in obtaining facial feature information. This technology can automatically and accurately locate the position of the face, and realize non-contact and imperceptible features. However, the multi-pose characteristics of the face will greatly affect the application based on face detection. Therefore, it is necessary to use ...
