Low-Altitude Aerial Video Surveillance via One-Class SVM Anomaly Detection from Textural Features in UAV Images

Abstract: In recent years, small-scale Unmanned Aerial Vehicles (UAVs) have been used in many video surveillance applications, such as vehicle tracking, border control, dangerous object detection, and many others. Anomaly detection can represent a prerequisite of many of these applications thanks to its ability to identify areas and/or objects of interest without knowing them a priori. In this paper, a One-Class Support Vector Machine (OC-SVM) anomaly detector based on customized Haralick textural features for aerial vi… Show more

“…SVM is used to train and recognize the extracted HOG features. Since SVM has high recognition accuracy even for small sample training results, it avoids a large number of manually labeled image categories, and, the fast-training speed saves a lot of time and improves efficiency [11,12]. In addition, HOG is used as a training feature, and as a gradient feature, HOG features themselves have high discriminative properties [13,14].…”

“…Considering that the scene exhibits an evident distinction when a UAV is present, using abnormality detection for UAV identification is a novel approach. There has been research using abnormal detection to identify UAVs [ 23 ], but it is still relatively scarce. However, there is extensive research on abnormal detection and these results can be used as an important reference.…”

“…We adopted the classical support vector machine (SVM) method [30] and gradient boosting decision tree (GBDT) algorithm of XGBoost [31] and LightGBM [32] to construct prediction models, and finally compared and analyzed the prediction results of different models. Support vector regression (SVR) is an application of SVMs in regression analysis, which can perform regression analysis and prediction on time series and is widely used in time series prediction prob-lems such as change and anomaly detection from textural features [33], fake stereo audio identification [34], or drowsiness estimation [35]. XGBoost is an integrated decision tree algorithm in which new trees can correct the results of existing trees in the model so that the model can be made satisfactory by continuously adding decision trees.…”
