Embodiment Construction

[0079] Below in conjunction with the accompanying drawings and specific embodiments, the present invention will be further clarified. It should be understood that these examples are only used to illustrate the present invention and not to limit the scope of the present invention. Modifications in the form of valence all fall within the scope defined by the appended claims of the present application.

[0080] A multi-graph matching method based on low-rank tensor recovery, the specific steps are as follows:

[0081] Step 1: Preprocess each frame of images and perform feature extraction, that is, extract features of interest points, and obtain position information of interest points.

[0082] SIFT (Scale Invariant Feature Transform) is often used to detect and describe local features in images. The description and detection of local image features can help identify objects. The SIFT algorithm finds feature points (key points) in different scale spaces. And calculate the specifi...

Abstract

The invention discloses a multi-image matching method based on low-rank tensor recovery, which includes the following steps: S1: preprocessing each frame of image and performing feature extraction, that is, extracting the feature of interest points; S2: interest of each frame of image Points are processed, and their high-order information features are extracted according to the topological relationship of the interest points; S3: Based on the multi-map cycle consistency, a multi-map high-order feature information tensor is constructed according to the global correspondence between the permutation matrix and image features; S4: Ranked Constraints as a standard, based on Alternating Direction Multiplier Method (ADMM) algorithm to solve the low-rank representation of multi-image high-order feature information tensor, can effectively calculate the corresponding optimal permutation matrix between multiple images, that is, the matching result matrix. The invention proposes a multi-image matching method based on low-rank tensor recovery, which realizes the consistency of image matching and improves the matching accuracy, and has important significance for image matching application research, target recognition and target tracking technology.

Description

technical field [0001] The invention relates to a multi-graph matching method based on low-rank tensor recovery, which can be used in the field of image processing, especially data analysis in the fields of images, graphics, genes and the like. Background technique [0002] As a hot issue in pattern recognition and computer vision research, image matching originated from research in the military field of the United States in the 1970s, and has received extensive attention and research. Image matching theory also plays a very important role in other research directions in the field of pattern recognition, such as image stitching technology, whose core is image matching; target tracking technology, which needs to rely on matching algorithms in the later stages; and for many detection and recognition algorithms, among which A large category is achieved by relying on matching technology. It can be seen that image matching has very important application value and theoretical res...
