Problems solved by technology
The present invention solves two main problems: one is to identify the faces of the same human body in different postures through the strategy of combining pedestrian re-identification and face recognition, thereby reducing the probability of large-angle posture correction; The problem of switching to the same pose interval for face comparison without correcting to the front face area and then performing face comparison

Embodiment Construction
[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts all belong to the protection scope of the present invention.
[0027] figure 1 It is the face search flowchart of the embodiment of the present invention, as figure 1 As shown, the method includes:
[0028] S1, training the Pose-Facenet model based on Facenet migration learning, and improving the training DREAM++ module based on the DREAM module. The former is used to subdivide the face label according to the pose interval, and the latter is used to convert the pose to the same pose interval;

The invention discloses a face searching method for a private photo album. Pose-Facenet is trained through transfer learning; the face tags in the training data are re-divided according to the face postures; and by combining an improved DREAM++ attitude generation module, face comparison is carried out as long as the postures are corrected to the same posture interval, and a non-front-face postureface does not need to be corrected into a front face for comparison by crossing large attitude angle changes, so that the negative influence of information loss caused by attitude adjustment is reduced. The characteristic that photos of adjacent shooting time in a private photo album generally have the same human body which is easy to identify is utilized; the method comprises the following stepsof: searching a front face which is easy to compare successfully in a photo album; a pedestrian re-identification technology is adopted to search human body images which belong to the same human bodyas the photo of the adjacent shooting time; therefore, the new posture face of the search target in the human body is obtained, the face information of all postures of the search target is enriched,the probability that large-angle posture correction needs to be conducted is reduced, and a better face search effect is achieved.
Description
technical field [0001] The invention relates to the technical field of image recognition, in particular to a face search method of a private photo album. Background technique [0002] With the popularization of smart phones and the cheapness of storage devices, more and more users choose to use mobile phones to take photos, and store the photos directly in the private photo album of the mobile phone without organizing them, which leads to the increasing of private photo albums. Huge and unmanageable. Through the face search technology, searching for photos containing specified faces in a huge private photo album has great practical significance for the management of photo albums. [0003] In the current face recognition technology, the basic principle of face search is to abstract the face image obtained by face detection into a high-dimensional vector through the neural network, and judge the similarity of the face by comparing the distance between the vectors. Thus, imag...
