Embodiment 1

[0035] See figure 1 , figure 1 It is a schematic flowchart of a face portrait recognition method based on face attributes provided by an embodiment of the present invention. A method of face portrait recognition based on face attributes provided by an embodiment of the present invention includes:

[0036] Obtain training sample set and test sample set;

[0037] Utilizing the training sample set to train a deep human face attribute representation model;

[0038] Using the deep face attribute representation model to obtain the face attribute representation features of the test sample set;

[0039] The similarity calculation is performed by using the face attribute representation features to identify the face portraits in the test sample set.

[0040] Specifically, the training sample set is used to train the deep face attribute representation model.

[0041] The test sample set is used to test the trained deep face attribute representation model, so as to determine the reco...

Embodiment 2

[0046] On the basis of the above-mentioned embodiments, the embodiment of the present invention specifically introduces the face portrait recognition method provided by the embodiment of the present invention. The recognition method specifically includes:

[0047] Step 1. Obtain a training sample set and a test sample set;

[0048] Specifically, the training sample set includes N groups of first sample groups, wherein each group of first sample groups includes a first face portrait, a first photo with the same identity as the first face portrait, and a For a second photo with a different identity from the first face portrait, the test sample set includes M groups of second sample groups, wherein each group of second sample groups includes a second face portrait and a photo with the same identity as the second face portrait. In the same third photo, M and N are natural numbers greater than 0.

[0049]Among them, having the same identity means the same person, and having differ...

Abstract

The present invention relates to a human face portrait recognition method based on human face attributes, comprising: obtaining a training sample set and a test sample set; using the training sample set to train a deep human face attribute representation model; using the trained deep human face The attribute representation model acquires the face attribute representation features of the test sample set; uses the face attribute representation features to perform similarity calculation to identify the second face portrait in the test sample set. The recognition method of the present invention uses a deep face attribute representation model to extract features from face portraits and photos, and overcomes the problem that the encoding feature information does not consider face attribute information when encoding face portraits and photos in the prior art, making the present invention The invention can obtain the attribute information of the human face, so that the recognition accuracy is higher, and the discrimination of the human face portrait is stronger.

Description

technical field [0001] The invention belongs to the technical field of image processing, and in particular relates to a face portrait recognition method based on face attributes. Background technique [0002] In the process of criminal investigation and case solving, it is generally difficult to obtain photos of criminal suspects. Generally, the face portraits of criminal suspects are drawn through the descriptions of witnesses or victims for subsequent face retrieval and recognition. Due to the great difference between face portraits and ordinary photos, it is difficult to obtain satisfactory recognition results by directly using traditional face recognition methods. Face portrait-photo recognition technology improves the recognition rate by reducing the difference between two different images, and has received extensive attention in the field of image processing.
