Problems solved by technology

As long as the similarity matching is successful, the matching is successful, which is prone to misidentification. For example, in voiceprint recognition, on the one hand, there is noise in the voiceprint, which is prone to recognition failure. On the other hand, the voiceprint is easy to be imitated, resulting in misidentification.

Embodiment

[0053] Please refer to figure 1 In the first aspect, the embodiment of the present invention provides an indisplicant application method for sounding identification and face recognition, including:

[0054] S1: In the early stage of the sound of the printed and controller rights, picking out a audio as an audio template;

[0055] In this step, the printer authority is a person who uses the princess of the princess, such as a legal representative, a high-management, etc. of the company. By collecting the sound of multi-segment indictant, a high-quality audio is selected as an audio template, such as picking a paragraph no noise, a clear voice as an audio template, the sound can be unified, such as "Open Indiator ""

[0056] S2: Collect the face image of the indection and controller rights, picking a representative image as a face image template;

[0057] In this step, the human face image of the printer is collected in advance, and the most representative image is selected as a fac...

Abstract

The invention provides a voiceprint recognition and face recognition combined seal control instrument application method and system, and relates to the field of seal safety use. The method comprises the following steps: acquiring an audio template and a face image template of a person authorized by a seal control instrument; when a seal control instrument user uses the seal control instrument, collecting audio of the user for audio authentication; after authentication, collecting a face image of a printing control instrument user, representing the image and a face image template by using sparse coding, and calculating the similarity between the face image of the user and the face image template; using a saliency detection method for carrying out saliency detection on a face image of a user and a face image template, carrying out sparse coding representation on a saliency region, and calculating the similarity of the saliency region of the face image and the face image template. A strategy of combining voiceprint recognition and face recognition is utilized, so that the identity recognition precision of a user of the printing control instrument is improved, and the safety coefficient of the printing control instrument is increased; the used method is classic and simple, does not need to consume more computing resources, and can reflect better real-time performance.

Description

Technical field [0001] Technical Field The present invention relates to the use of the security seal, in particular, the application relates to a printing apparatus control method and system for voiceprint recognition and face recognition in combination. Background technique [0002] As technology advances, more and more machine-stamped approach has replaced the artificial stamp mode, the Indian-controlled instrument can minimize the consumption of human resources at the same time precise stamped. At the same time, due to the stamp machine often requires significant contracts, legal documents, etc. stamp, stamp machine security has been more and more attention. [0003] At present, many research institutions, technology companies use the seal using face recognition technology to enhance the safety of the machine seal, the market a lot of Indian-controlled instrument also used this method. However, this method still has some errors can not be very precise control of the printing a...
