Problems solved by technology

[0004] For patients with facial paralysis, during face recognition, lesions have occurred on their faces. At this time, some facial features collected in real time are different from those without lesions, which can easily lead to failure to recognize or wrong recognition.

Embodiment 1

[0026] The scene targeted by the present invention is: the facial lesion area of ​​a patient with facial paralysis and the aggravation and rehabilitation of the condition, which are different from the facial features of a healthy person, and the facial information in the identity database is the information of the patient when he is healthy, for example This will have a great impact on the face recognition of patients with facial paralysis. Directly comparing a lesioned face with a healthy face, it is easy to operate misidentification and misjudgment. Firstly, obtain the horizontal corner image of the patient with facial paralysis. The size of the horizontal corner image is the same as that of the patient's front face image. Each pixel value in the horizontal corner image represents the lateral rotation angle of the patient's face when the pixel is located at the boundary of the side face facial image. That is, when the patient's head is rotated laterally by an angle correspon...

Embodiment 2

[0070] This embodiment provides a system embodiment. An intelligent face recognition system suitable for patients with facial paralysis, the system mainly includes a horizontal corner image acquisition module, an optimal face deflection angle acquisition module and a patient's healthy face image acquisition module, specifically:

[0071] The horizontal corner image acquisition module is used to acquire the horizontal corner image of the patient with facial paralysis. The horizontal corner image is the same size as the patient's front face image. Each pixel value in the horizontal corner image represents the patient's face when the pixel is located at the border of the side face Lateral rotation angle;

[0072] The optimal face deflection angle acquisition module is used to obtain the optimal face deflection angle according to the patient's condition information and the lateral corner image, so that the patient can rotate laterally at the optimal face deflection angle to obtain...

Abstract

The invention provides an intelligent face recognition method and system suitable for a facial paralysis patient, and the method comprises the steps: obtaining a transverse corner image of the facial paralysis patient, and enabling the transverse corner image to be the same as the front face image of the patient in size, wherein each pixel value in the transverse rotation angle image represents the transverse rotation angle of the face of the patient when the pixel is located at the boundary of the side face; obtaining an optimal face deflection angle according to the condition information of the patient and the transverse rotation angle image, enabling the patient to transversely rotate at the optimal face deflection angle to obtain a side face image of the patient, and shielding the lesion position of the patient in the side face image of the patient; and correcting the side face image of the patient to obtain a healthy face image of the patient, and performing face recognition on the patient according to the healthy face image of the patient. According to the face recognition method, a face recognition technical scheme for the facial paralysis patient is provided, the influence of the lesion position of the facial paralysis patient on face recognition is eliminated, and face recognition can be accurately carried out on the facial paralysis patient.

Description

technical field [0001] This application relates to the field of artificial intelligence, in particular to an intelligent face recognition method and system suitable for patients with facial paralysis. Background technique [0002] Face recognition is a biometric technology for identification based on human facial feature information. It has developed rapidly in recent years and is used in various scenarios. In addition to security and financial fields, face recognition is also used in transportation, education, It has been widely used in medical, police, e-commerce and many other scenarios. The current face recognition often uses the currently collected face image to compare the similarity with the faces in the identity database, so as to perform face recognition. [0003] However, in practical applications, the face collected in real time is quite different from the face in the previous face database, and it is difficult to perform face recognition. If the recognition is ...
