Abstract

The invention relates to the technical field of behavior analysis, in particular to a method and device for labeling abnormal behaviors. The method comprises the steps of pre-training a neural networkbased on a current abnormal behavior data set to obtain a first neural network model; copying all network architectures and model parameters except the output layer in the first neural network model,and creating a second neural network model; adding an output layer of which the tensor size corresponds to the number of abnormal behavior detection categories into the second neural network model; training the second neural network model added with the output layer according to a target data set obtained by labeling in a PASCAL VOC labeling mode or a COCO labeling mode to obtain an abnormal behavior labeling model; inputting the to-be-annotated data set into the abnormal behavior annotation model, and annotating each piece of to-be-annotated data in the to-be-annotated data set to obtain anannotated data set; judging whether the labeled data set is correctly labeled or not; and inputting the data with wrong annotations into the abnormal behavior annotation model for re-annotation.

Description

technical field [0001] The invention relates to the technical field of behavior analysis, in particular to a method and device for marking abnormal behavior. Background technique [0002] Abnormal behavior detection is an important branch of human behavior recognition and an important research task in the field of computer vision. Abnormal behavior detection mainly refers to the classification and detection of specific behaviors. Specific behaviors can be fights and stampedes in public places. The abnormal behavior detection process mainly includes two parts: target feature extraction and feature classification. Target feature extraction refers to extracting features that can represent abnormal behaviors from video data. Feature classification refers to classifying the extracted features, for example, classifying the extracted feature vectors through a support vector machine (Support Vector Machine, SVM). [0003] With the development of deep learning in the field of comp...
