Abstract

The invention discloses an object extraction method and device, and the method and device achieve the simple and effective obtaining of better local features, and better guarantee the subsequent recognition of an object.

Description

technical field [0001] This application relates to but is not limited to computer technology, especially an object extraction method and device. Background technique [0002] Feature extraction (FE, Feature Extraction) refers to the method and process of using a computer to extract characteristic information in an image. [0003] Global Feature refers to the overall attribute of the image and is a low-level visual feature at the pixel level. Common global features include color features, texture features, and shape features. Global features have the characteristics of good invariance, simple calculation, and intuitive representation, but the global feature description is not suitable for image aliasing and occlusion. Local Features are features extracted from local areas of the image, including edges, corners, lines, curves, and areas with special attributes. [0004] How to better obtain local features so as to ensure subsequent applications is an urgent problem to be sol...
