Embodiment Construction

[0018] The identification method based on gait of the present invention comprises the following steps:

[0019] 1. Extract the gait contour;

[0020] 2. Detection of gait cycle;

[0021] 3. Extract effective gait features and process the gait features. Before extracting gait features, extract a periodic subsequence in the gait sequence;

[0022] Fourth, pattern classification, using classifiers to complete classification recognition.

[0023] Further, the process of extracting the gait contour in step 1 is:

[0024] a. Extract image background;

[0025] b. Fill holes and eliminate the influence of random noise through morphological processing;

[0026] c, The complete gait profile is extracted from the image based on single connectivity analysis.

[0027] Further, the second step is to detect the pedestrian's gait cycle according to the profile aspect ratio parameter or the leg closed area parameter.

[0028] Further, the extraction of gait features in step three include...

Abstract

The invention provides an identity identification method based on a gait and aims at solving the problem that in the prior art, no identity identification method based on the gait exists. The technical key point comprises the following steps of 1, extracting a gait outline; 2, detecting a gait period; 3, extracting a valid gait feature and processing the gait feature and extracting a sub-sequence from a gait sequence before the gait feature is extracted; and 4, classifying modes and finishing classification and identification through a classifier. Compared with a biological recognition technology, the method has the advantages that the method is simpler and more practical. The method has good adaptation to the low-quality side outline; the identity identification can be carried out rapidly; and the method has great help in arresting a criminal.

Description

Technical field: [0001] The invention relates to the field of recognition of body movement, in particular to a gait-based identity recognition method. Background technique: [0002] Biometric technology uses the characteristics of the human body for identity verification, these features include fingerprints, voice, face, iris, DNA, walking gait, etc. Unlike other biometric technologies, gait recognition can be performed at a long distance, at a certain distance Although the face is blurred, the gait is clearly visible. Gait recognition is also non-compulsive and does not require the recognized person to cooperate deliberately, making it difficult for the recognized person to detect, and has the characteristics of not being easy to hide and imitate. Therefore, the gait The research on recognition is helpful to apprehend criminals, but there is not much research on gait recognition at present, and there is no perfect gait-based identification method.
