Abstract

The embodiment of the invention discloses a fingerprint foreign matter detection method and device, electronic equipment and a storage medium. The method comprises the following steps: acquiring an image acquired by a fingerprint sensor; performing feature extraction on the image to obtain target feature information of the image; inputting the target feature information into a pre-trained network model, and obtaining a foreign matter detection result of an image output by the network model; and determining an image processing mode based on a foreign matter detection result. According to the method, the target feature information of the image is extracted, the target feature information is input into the pre-trained network model to perform foreign matter detection on the image, and the processing mode of the image is determined according to the foreign matter detection result, so that the accuracy of fingerprint detection is improved.

Description

technical field [0001] The present application relates to the technical field of fingerprint identification, and more specifically, to a method, device, electronic device and storage medium for detecting fingerprint foreign matter. Background technique [0002] With the development of terminal technology and image processing technology, fingerprint recognition technology has been widely used. It is a common security mechanism for identifying identities. It not only brings security protection to personal private devices, but also brings convenience to users. . The fingerprint identification technology requires the user to collect the user's fingerprint information by touching the surface of the fingerprint sensor of the terminal with a finger. However, in the process of collecting the user's fingerprint information, foreign matter such as water may be encountered on the surface of the fingerprint sensor itself or on the user's finger, so that the accuracy of fingerprint dete...
