Abstract

The invention discloses a dynamic face database establishing method, which is characterized in that the method comprises the following steps: 1) carrying out real-time face image acquisition, and carrying out face interception on the collected images according to a set effective face standard to capture effective face images; 2) carrying out dynamic intelligent face algorithm processing on the effective face images to obtain face image feature points; and 3) keeping the obtained face image feature points in real time to form a dynamic face database. By capturing the effective face images in the collected images and judging the effective face images, a temporary target face database is established, and recognition rate and authentication efficiency can be improved.

Description

technical field [0001] The invention relates to a method for establishing a dynamic portrait database, in particular to a method for establishing a dynamic portrait database which can effectively improve the recognition rate. Background technique [0002] In recent years, the security industry has set off a wave of upsurge in portrait recognition, and many manufacturers have launched related products, making portrait recognition a hot technology direction in the industry. [0003] Although the existing portrait recognition technology has great functions, we still encounter many problems in practical applications. Among them, the image quality of the portrait has a high impact on the recognition rate. The image quality is poor, the recognition degree is low, and there are few effective features. Sometimes it is difficult to confirm the identity even with the naked eye. Image quality is affected by many factors, such as lighting, posture, expression, portrait size, clarity, e...
