Abstract

The invention discloses an image processing method, a descriptor extraction method and device and electronic equipment. The image processing method comprises the steps that a first original image and a second original image are collected, the first original image is one of an original target image and a background image, and the second original image is the other one of the original target image and the background image; performing local brightness alignment processing on the first original image to obtain a first processed image; and obtaining a background-removed target image based on the first processing image and the second original image. The technical problem that a clear target image cannot be obtained by removing background textures in different environments in the prior art can be solved.

Description

technical field [0001] The present invention relates to an image processing technology, in particular, to an image processing method, a descriptor extraction method, a device thereof, and an electronic device. Background technique [0002] With the development of electronic technology and communication technology, electronic images are used more and more widely, but there are often background content that users do not want to appear in electronic images. For example, in the field of under-screen optical fingerprint recognition, the sensor is located below a specific area of ​​the screen. When the user's finger presses this area, the phone screen lights up, and the sensor receives the reflection from the surface of the user's finger to form a fingerprint image. Since the display screen is separated from the sensor and the finger, the imaging result contains not only the fingerprint information, but also the texture information of the display screen itself (that is, the backgr...
