Problems solved by technology

However, due to different identification devices, different identification algorithms, and certain similarities between fingerprints of different people, it is impossible to completely avoid fingerprint recognition (that is, false fingerprints are misidentified as real fingerprints)
Therefore, there are still fingerprint identification problems in the existing fingerprint identification technology, and after the fingerprint identification problem occurs, it is difficult to restore the identification scene to find the identification image in the fingerprint library. How to avoid the fingerprint identification problem becomes a problem that needs to be considered

Embodiment 1

[0031] First, refer to figure 1 An example electronic device 100 for implementing an image search method, apparatus and electronic device according to an embodiment of the present invention will be described.

[0032] Such as figure 1 Shown is a schematic structural diagram of an electronic device. The electronic device 100 includes one or more processors 102, one or more storage devices 104, an input device 106, an output device 108, and an image acquisition device 110. These components pass through a bus system 112 and / or other forms of connection mechanisms (not shown). It should be noted that figure 1 The components and structure of the electronic device 100 shown are only exemplary, not limiting, and the electronic device may also have other components and structures as required.

[0033] The processor 102 can be implemented in at least one hardware form of a digital signal processor (DSP), a field programmable gate array (FPGA), and a programmable logic array (PLA), and...

Embodiment 2

[0040] This embodiment provides an image search method, which can be executed by the aforementioned electronic device, see figure 2 The flow chart of the image search method is shown, the method mainly includes the following steps S202 to S204:

[0041] Step S202, acquiring the target template image features matching the image to be recognized from the pre-established template feature database, and determining the target template image identity of the target template image features.

[0042] Image features of multiple template images are stored in the above-mentioned template feature library. Since image features are irreversible, image features cannot be reversely converted into images. When there are target template image features that match the image to be recognized in the template feature library, that is, there are target template image features in the template feature library that are highly similar to the image features of the image to be recognized, in order to obtai...

Embodiment 3

[0068] On the basis of the above-mentioned embodiments, this embodiment provides an example of applying the above-mentioned image search method to perform image search for fingerprint identification. Specifically, it can be executed by referring to the following steps a to f:

[0069] Step a: collecting a preset number of fingerprint images, and registering a fingerprint template feature library according to the collected preset number of fingerprint images.

[0070] Use the mobile fingerprint module to collect the user's fingerprint image, use the collected preset number of fingerprint images as template images, extract image feature points from each template image, add the image features of each template image to the fingerprint template feature library, and Each template image is added to the fingerprint gallery. In practical applications, the image features of each template image may also be marked, for example, when the preset number is 20, the image features of each temp...

Abstract

The invention provides an image search method and device and electronic equipment, and relates to the technical field of image processing, and the method comprises the steps: obtaining a target template image feature matched with a to-be-recognized image from a pre-built template feature library, and determining a target template image identification of the target template image feature, wherein image features of a plurality of template images are stored in the template feature library and the object to which the to-be-identified image belongs is different from the object to which the target template image feature belongs; obtaining an image identifier of each image in a preset image library, determining a target image corresponding to the target template image identifier in the preset image library according to each image identifier, and taking the target image as a fake image, wherein the image identifier comprises a unique code of the image and wherein the image identifier of the target image is the same as the target template image identifier. According to the method and the device, a false recognition image which can cause the false recognition problem can be found from the preset image library, so that the fingerprint false recognition problem can be avoided to a certain extent.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to an image search method, device and electronic equipment. Background technique [0002] With the development and maturity of AI biotechnology, fingerprint recognition has been integrated into mobile devices by most major manufacturers and has become the first choice for mobile unlocking and security management. With the expansion of fingerprint application fields, the requirements for fingerprint security performance are getting higher and higher. However, due to different recognition devices, different recognition algorithms, and certain similarities between fingerprints of different people, it is impossible to completely avoid fingerprint recognition (that is, false fingerprints are mistakenly identified as true fingerprints). Therefore, the existing fingerprint identification technology still has the problem of fingerprint identification, and after the fingerprint iden...
