Summary:Disclosed are a method for establishing a feature tree structure of a digital image and an image object identification method, which are applied to establishment of a tree structure of feature point descriptors of the digital image and identification of the similarity of an image to be identified. The method for establishing a feature tree structure includes loading an original image, and performing image layer processing on the original image, and generating a plurality of sub-images; selecting one of the plurality of sub-images, and subjecting the selected sub-image to a Gaussian image difference processing and generating a plurality of sequential images; determining at least one feature point according to the sequential images, and generating feature point descriptor corresponding to the feature points; subjecting the feature point descriptors to group processing to generate a feature tree structure; generating feature points and feature point descriptors for an image to be identified; and loading the feat
