Embodiment Construction

[0061] The implementation of the present application will be described in detail below with reference to the accompanying drawings and examples, so as to fully understand and implement the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects.

[0062]With the rapid development of the mobile Internet, mobile intelligent terminal devices such as smartphones and tablet computers are becoming more and more popular, and images have become an indispensable information transmission medium for people's daily life. In image applications, such as image detection and image matching, it is necessary to use feature points to describe the image to achieve image retrieval and matching. The image can be an electronic product advertisement, or a content image such as a certain brand product. Therefore, in a large number of images with various categories and complex designs, the information provided by the images can...

Abstract

An embodiment of the present invention provides an image feature extraction method and device, the method comprising: acquiring an image to be processed, calculating the salient features of the image to be processed, obtaining a feature image, performing edge detection on the feature image, and obtaining the edge features of the feature image, extract local features of the image to be processed, and use the edge features to filter the local features to obtain image features of the image to be processed. The embodiments of the present invention improve the accuracy of image features.

Description

technical field [0001] The present application belongs to the technical field of image processing, and in particular relates to an image feature extraction method and device. Background technique [0002] Image feature extraction has a wide range of applications in the fields of computer vision and image processing. For example, in image retrieval, it is necessary to compare the input image with the image in the image library to find the retrieved image that matches the input image, and to compare the input image with the image library Comparing the images in the image is to compare the image features of the input image with the image features of the images in the image library. [0003] In the prior art, image feature extraction usually extracts local features of the image, such as SIFT (ScaleInvariantFeature Transform, scale-invariant feature transformation), but traditional local feature extraction will extract a lot of feature points, resulting in relatively large data v...
