Abstract

The invention is applicable to the field of image processing, and provides a feature point selection method, a terminal and a storage medium. The feature point selection method comprises the steps ofacquiring multiple first ear images, wherein the multiple first ear images are ear images of the same human ear; respectively identifying ear feature points in each first ear image, wherein the numberof the ear feature points in each first ear image is greater than 1; respectively calculating combined features of the ear feature points in each first ear image; and screening out a target ear imagefrom the plurality of first ear images according to the combined features, and obtaining target feature points according to the ear feature points of the target ear image. According to the embodimentof the invention, the reliability of the ear feature points can be improved.

Description

technical field [0001] The present application belongs to the field of image processing, and in particular relates to a feature point selection method, a terminal and a storage medium. Background technique [0002] Ear recognition is a new biometric recognition technology emerging in recent years. Ear feature points identified from ear images using ear recognition technology are an important part of biometric identification and ergonomic design of ear-wearing products. [0003] The results obtained by the existing ear feature point extraction methods have poor reliability, and the selected ear feature points are not conducive to the use in biometric identification or ergonomic design. Contents of the invention [0004] Embodiments of the present application provide a method for selecting feature points, a terminal, and a storage medium, which can solve the current problem of low reliability of ear feature points. [0005] The first aspect of the embodiment of the present...
