Embodiment 1

[0026] See figure 1 , figure 1 is a schematic flowchart of a method for generating an adversarial disturbance of an object detection model provided by an embodiment of the present invention. For the convenience of understanding and description, the embodiment of the present invention takes an object detection model in the field of image processing as an example to describe its anti-disturbance generation method in detail. The target object described in the embodiment of the present invention may be an object such as a person, an animal, or a building included in the image to be detected. It should be noted that the first, second, and i-th before the set of adversarial disturbances, adversarial samples, and target object confidences described in this embodiment are only used to distinguish the adversarial disturbances and countermeasures corresponding to different adversarial disturbance correction processes. Confidence sets of samples or target objects, without other restric...

Abstract

The embodiment of the invention discloses an anti-disturbance generation method and device for an object detection model. The method comprises the following steps: acquiring a first anti-disturbance and a first training sample set; And determining a first confrontation sample according to the first training sample and the first confrontation disturbance in the first training sample set, and performing first confrontation disturbance correction on the first confrontation disturbance based on a first target object confidence set corresponding to the first confrontation sample determined by the object detection model to obtain a second confrontation disturbance. After a new training sample is obtained from the first training sample set each time, new anti-disturbance is obtained through correction again based on the new training sample and the anti-disturbance obtained through last anti-disturbance correction. And when the N confrontation disturbances obtained by N times of correction areconverged, determining the (N + 1) th confrontation disturbance obtained by the Nth confrontation disturbance correction as the target confrontation disturbance corresponding to the object detectionmodel. By adopting the embodiment of the invention, the efficiency and the applicability of the anti-disturbance generation method can be improved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for generating an anti-disturbance of an object detection model. Background technique [0002] With the continuous development of computer technology and deep learning technology, as a basic and very important research focus in the field of artificial intelligence and computer vision, the development of object detection technology cannot be ignored. Under the existing environment, object detection technology can already be applied in some fields. For example, in automatic driving or intelligent video surveillance, object detection technology has great practical value. Moreover, it is foreseeable that the application field of object detection technology will continue to expand, so people are paying more and more attention to issues such as the stability and security of object detection algorithms used in object detection technology. [0003] In the prior art...
