It should be noted that in the embodiments of the present application, the term "comprising" is used to indicate the presence of the features stated hereinafter, but does not exclude the addition of further features.
FIG. 1 is a block diagram of an image processing system of some embodiments of the present application. For example, the image processing system may be a platform for applications such as identity authentication, information registration, account activation, and the like.
The image processing system may include one or more of a server 110, a network 120, a terminal 130, and a database 140, and the server 110 may include a processor therein that performs operations of instructions.
In some embodiments, the server 110 may be a single server or a group of servers. The set of servers can be centralized or distributed (e.g., the servers 110 can be a distributed system). In some embodiments, the server 110 may be local or remote to the terminal. For example, server 110 may access information and/or data stored in terminal 130 or database 140, or any combination thereof, via network 120. As another example, server 110 may be directly connected to at least one of terminal 130 and database 140 to access stored information and/or data. In some embodiments, the server 110 may be implemented on a cloud platform; by way of example only, the cloud platform may include a private cloud, a public cloud, a hybrid cloud, a community cloud (community cloud), a distributed cloud, an inter-cloud, a multi-cloud, and the like, or any combination thereof. In some embodiments, the server 110 may be implemented on an electronic device 200 having one or more of the components shown in FIG. 2 in the present application.
In some embodiments, the server 110 may include a processor. In some embodiments, a processor may include one or more processing cores (e.g., a single-core processor (S) or a multi-core processor (S)). Merely by way of example, a Processor may include a Central Processing Unit (CPU), an Application Specific Integrated Circuit (ASIC), an Application Specific Instruction Set Processor (ASIP), a Graphics Processing Unit (GPU), a Physical Processing Unit (PPU), a Digital Signal Processor (DSP), a Field Programmable Gate Array (FPGA), a Programmable Logic Device (PLD), a controller, a microcontroller Unit, a Reduced Instruction Set computer (Reduced Instruction Set computer), a microprocessor, or the like, or any combination thereof.
In some embodiments, a database 140 may be connected to network 120 to communicate with one or more components in an image processing system (e.g., server 110, terminal 130, etc.). One or more components in the image processing system may access data or instructions stored in database 140 via network 120. In some embodiments, the database 140 may be directly connected to one or more components in the image processing system (e.g., the server 110, the terminal 130, etc.); alternatively, in some embodiments, database 140 may also be part of server 110.
Fig. 2 illustrates a schematic diagram of exemplary hardware and software components of an electronic device of some embodiments of the present application.
For example, a processor may be used on the electronic device 200 and to perform the functions herein.
The electronic device 200 may be a general purpose computer or a special purpose computer, both of which may be used to implement the resource handling methods of the present application. Although only a single computer is shown, for convenience, the functions described herein may be implemented in a distributed fashion across multiple similar platforms to balance processing loads.
For example, the electronic device 200 may include a network port 210 connected to a network, one or more processors 220 for executing program instructions, a communication bus 230, and a different form of storage medium 240, such as a disk, ROM, or RAM, or any combination thereof. Illustratively, the computer platform may also include program instructions stored in ROM, RAM, or other types of non-transitory storage media, or any combination thereof. The method of the present application may be implemented in accordance with these program instructions. The electronic device 200 also includes an Input/Output (I/O) interface 250 between the computer and other Input/Output devices (e.g., keyboard, display screen).
For ease of illustration, only one processor is depicted in the electronic device 200. However, it should be noted that the electronic device 200 in the present application may also comprise a plurality of processors, and thus the steps performed by one processor described in the present application may also be performed by a plurality of processors in combination or individually. For example, if the processor of the electronic device 200 executes steps a and B, it should be understood that steps a and B may also be executed by two different processors together or separately in one processor. For example, a first processor performs step a and a second processor performs step B, or the first processor and the second processor perform steps a and B together.
For convenience of description, in the embodiment of the present application, an example of a resource processing method based on a block chain is provided only by taking an application program sharing an automobile service as an example, and in practical applications, the embodiment of the present application does not limit the method.
In addition, it should be noted that the resource processing method based on the blockchain effectively utilizes the blockchain technology and the attribute that data on the blockchain is not changeable, and can effectively avoid the possibility that the pre-stored resources of the user are manually operated when the user uses the shared product, so that the user resource use is transparent, and the resource state can be checked at any time, thereby ensuring the benefit of the user and improving the user experience.
Fig. 3 shows a schematic flowchart of an image processing method provided in an embodiment of the present application, where an execution subject of the embodiment may be a terminal, or may be a device with a processing function, such as a server and a processor, as shown in fig. 3, the method includes:
s101, acquiring an image to be checked, wherein the image to be checked comprises information to be checked.
Generally, when a user registers software or applies for application access authorization, a portrait of the user or a related certificate photo of the user needs to be collected and matched with related information of the user stored in a background database of a server for identity verification.
Optionally, an image to be checked is obtained, where the image to be checked may be a user head portrait shot in real time, or an identification card image, a bank card image, or a driver license image of the user. The terminal can be used for carrying out image acquisition by the camera, or the terminal can be used for carrying out external camera, and image acquisition is carried out, and the terminal is not limited specifically.
The acquired image to be audited includes information to be audited, for example: when the collected image is a face image of a user, the corresponding information to be audited can be the characteristics of the five sense organs and the like; when the acquired identity card image is acquired, the corresponding information to be audited may include: identity card number, user name, identity card portrait page, identity card national emblem page, etc.; when the collected image is a bank card image, the corresponding information to be audited may include: bank card number, bank name, etc. Specifically, the acquired information to be audited is different according to different image types.
S102, verifying whether the image to be verified meets the verification condition by adopting at least one verification model corresponding to the preset verification rule, and obtaining a verification result.
In step S101, to-be-audited information of the to-be-audited image is acquired, where the to-be-audited information is also image feature information included in the to-be-audited image. The terminal can audit the acquired information to be audited according to an audit model which is trained in advance and packaged in the terminal, and whether the acquired image to be audited meets the requirements or not is verified.
It should be noted that, in the present application, different models need to be provided for different audit information, for example, a model for processing a human face is different from a model for processing a vehicle. Correspondingly, a uniform model call interface may be configured in the client, and the types of audit information that may be needed for different functions that are enabled by the user at the client are also different, for example: starting a user identity auditing function, wherein the corresponding acquired image to be audited can be a face image, an identity card image and the like; the client side can call one or more corresponding models in a self-adaptive mode through the model call interface to perform operations such as image detection and identification without additionally changing specific contents of the client side or the terminal.
Optionally, according to the information to be audited of different images to be audited, different audit models can be correspondingly selected for image auditing, for example: for the image text information, an image type classification model, a quality classification model or a text content classification model and the like can be adopted for auditing; for the audio and video images, a sound quality classification model, a video target detection model or a video fluency detection model and the like can be adopted for auditing.
In some embodiments, the audit models correspond to preset audit rules, and the preset audit rules of the audit models are adopted to audit the information to be audited. For example: for the identity card image, the image classification can be carried out according to the rules of the image position frame or the certificate number length and the like in the image type classification model. Usually, the number of the identification card is 18 bits, the number of the bank card is 19 bits, and then whether the type of the identification card is correct or not can be determined according to the length of the target number, in addition, the size of the identification card is different from that of the bank card, and auxiliary judgment and the like can be carried out according to the size of the set position frame.
S103, displaying the auditing result.
Optionally, the image review may be performed through a plurality of review models integrated on the terminal, and the terminal may obtain a review result and feed the review result back to the user. Optionally, the display may be performed through a terminal display screen, and the result display may also be performed through an indicator light, for example: and if the audit is passed, the terminal indicator light is green, and if the audit is not passed, the indicator light is red, and the like. The embodiment is not particularly limited with respect to the display manner of the result.
In summary, according to the image processing method provided by the embodiment of the application, the combination of the audit models is performed according to the preset rules and the information of the image to be audited through the multiple audit models on the terminal, the acquired image to be audited is audited, and the audit result is fed back to the user, so that the image audit time is greatly saved, and the image audit efficiency is improved to a certain extent.
