Embodiment 1

[0030] figure 1 It is a schematic flow chart of an image detection method provided by the embodiment of the present invention. This embodiment is applicable to the detection of tampered images. The method can be executed by an image detection device, which can be implemented by software and / or Realized in the form of hardware.

[0031] It should be noted that before explaining the technical solutions of the embodiments of the present invention, the application scenarios of the embodiments of the present invention will be illustrated first:

[0032] The image detection method in the embodiment of the present invention refers to detecting whether an image has been tampered with. Image tampering includes splicing and tampering of images, text tampering in images, etc. The image detection method in the embodiment of the present invention is mainly aimed at splicing and tampering of images. Image splicing and tampering refers to copying the content of one or more images in the i...

Embodiment 2

[0054] figure 2 It is a schematic flow chart of an image detection method provided by the embodiment of the present invention. The embodiment of the present invention refines step 140 and step 150 on the basis of the optional solutions of the above embodiments. The specific refinement process is described in the present invention Detailed elaboration is carried out in the embodiment. Wherein, technical terms that are the same as or similar to those in the foregoing embodiments will not be described in detail.

[0055] Such as figure 2 As mentioned above, the image detection method provided by the embodiment of the present invention specifically includes the following steps:

[0056] S210. Input the image to be detected into the feature map conversion model to obtain at least three feature maps.

[0057] S220. Input the at least three feature maps into corresponding target feature vector extraction models to obtain target feature vectors.

[0058] S230. Input the target f...

Embodiment 3

[0073] image 3 It is a schematic structural diagram of an image detection system provided in an embodiment of the present invention. The image detection system in the embodiment of the present invention can implement the image detection method in the above-mentioned embodiments.

[0074] It should be noted that the image detection system of the embodiment of the present invention includes a feature map conversion model (the feature map conversion model includes a constrained convolution sub-model, a heavy compression sub-model, and a noise sub-model), a target feature vector extraction model (with the same network structure Siamese network), feature processing model (long short-term memory network model) and target data processing model (attention sub-model and decision-making sub-model).

[0075] The input of the feature map conversion model is the image to be detected, and the output is three feature maps, including the constraint map corresponding to the constrained convol...

Abstract

The embodiment of the present invention discloses an image detection method, device, electronic equipment, and storage medium. The method includes: inputting the image to be detected into a feature map conversion model to obtain at least three feature maps; wherein, the feature map The conversion model includes a constrained convolution sub-model, a heavy compression sub-model and a noise sub-model; the at least three feature maps are respectively input into the corresponding target feature vector extraction model to obtain the target feature vector; the target feature vector includes Three feature sub-vectors; input the target feature vector into the feature processing model to obtain the target global feature vector; process the target global feature vector based on the target data processing model to obtain the image corresponding to the image to be detected An image classification result: based on the image classification result, determine a detection result corresponding to the image to be detected. The technical solutions of the embodiments of the present invention improve the accuracy of image detection.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of image detection, and in particular, to an image detection method, device, electronic equipment, and storage medium. Background technique [0002] With the development of face recognition technology, face recognition has become a common means of identity authentication. In the tax field, enterprise registered ticket collectors often need to upload real-name authentication avatar data for review and recording. However, an efficient and accurate intelligent detection method for real-name authentication avatars has not yet appeared in the industry. Therefore, there is an urgent need for an image detection method to achieve reliable and accurate detection of real-name authentication avatars. Contents of the invention [0003] Embodiments of the present invention provide an image detection method, device, electronic equipment, and storage medium, so as to detect tampered images and impr...
