Title:
IMAGE PROCESSING METHOD AND IMAGE DETECTION MODEL EVALUATION METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/071841
Kind Code:
A1
Abstract:
Disclosed in embodiments of the present application are an image processing method and an image detection model evaluation method and device. The image processing method comprises: obtaining a first image and a second image, the first image being superimposed on the second image to obtain a third image used for attacking an image detection model; determining a range of a pixel coordinate parameter and a range of an angle parameter on the basis of a partial region (i.e., a first region) in the second image, the range of the pixel coordinate parameter being a set of pixel coordinates of the first region in the second image; and determining a first pixel coordinate set and a first angle on the basis of the range of the pixel coordinate parameter and the range of the angle parameter, the first pixel coordinate set indicating a position of the first image being superimposed on the second image, and the first angle indicating a rotation angle of the first image superimposed on the second image. By using the embodiments of the present application, an adversarial sample having high aggressiveness and good practicability can be obtained for effectively evaluating the robustness of the image detection model.
