An image feature point detection method, terminal device and storage medium

Abstract

This application is applicable to the technical field of image recognition, and provides an image feature point detection method terminal device and a computer-readable storage medium. The method includes: acquiring initial images of multiple categories of natural scenes, and targeting each category of natural scenes , lift the initial feature points from the initial image, according to the corresponding relationship of the initial feature points in the initial image of the current natural scene, use the initial feature points that meet the preset conditions as the target feature points of the current category, and include the initial feature points of the target feature points The image is used as the training image of the current category, through the training images in the training sample set, the deep neural network constructed is trained to obtain the trained deep neural network, and based on the trained deep neural network, the image to be detected is detected to obtain For the feature points in the image to be detected, the detection accuracy in scene detection can be improved through the present application.

Description

technical field [0001] The present application belongs to the technical field of image recognition, and in particular relates to an image feature point detection method, a terminal device, and a computer-readable storage medium. Background technique [0002] With the continuous development of computer vision and the continuous improvement of user needs, many image processing technologies have emerged. When performing various processing on images, in order to obtain better processing effects, sometimes it is necessary to identify the scene of the image, [0003] At present, most of the detection and recognition of image scenes is to calculate certain response values ​​of image pixels one by one in the image scale space, and obtain local extremum based on pixel position and scale to obtain feature point detection results. However, the detection accuracy of this image feature point detection method is low. Contents of the invention [0004] In view of this, embodiments of t...
