Abstract

Embodiments of the disclosure disclose an object recognition method and apparatus, an electronic device and a storage medium. The method comprises: determining a background area of a target object in an image to be identified, and determining a background pixel value according to pixel values of a plurality of pixels in the background area; cutting a target object area in the image to be identified, and identifying target image pixels belonging to the target object from the target object area according to the background pixel value.
